Morocco and PPDA 25.1: When Sitting Deep Is a Choice, Not a Concession

On December 10, 2026, at Al Thumama Stadium in Doha, Youssef En-Nesyri rose one beat higher than the Portugal defender and headed the ball into the net. The stands erupted. I was sitting in front of a screen in Busan, my hand resting on the keyboard, my eyes fixed on the metrics table I had built before kick-off. Among dozens of flickering lines, one made me pause longer than all the rest: PPDA 25.1. That number said Morocco allowed their opponents to pass the ball freely across roughly the final third, and barely reacted in the harmless zones. The media called it defending. I called it a plan designed down to the last square metre.

That night I finished my first draft at nearly three in the morning. But it took me two more days, after cross-checking all three knockout matches, before I dared to assert what I believed: Morocco were not being pinned back. Morocco were choosing to sit deep. The gap between those two phrases is far larger than it appears, and this entire article exists to explain why.

To understand PPDA 25.1, you have to place it inside the frame that produced it. In August 2026, only three months before the World Cup began, the Moroccan football federation appointed Walid Regragui as head coach, replacing Vahid Halilhodzic. Most Asian media at the time read it as a late gamble: a national team that had reached the knockout rounds but never passed the quarter-finals, handed a domestic coach just months before the biggest stage. Regragui had no time to build an attacking system from scratch. He had time to do exactly one thing: reshape how his team defended.

Morocco were drawn in Group F with Croatia, Belgium and Canada. They topped the group: a 0-0 draw with Croatia, a 2-0 win over Belgium, a 2-1 win over Canada. In the knockout rounds, their opponents were Spain, then Portugal, then France in the semi-final. Three teams whose combined squad transfer value dwarfed that of a North African nation. And that was precisely the context that turned the PPDA metric into the centre of everything I wrote afterwards.

PPDA stands for Passes Allowed Per Defensive Action. It measures how many passes a team allows its opponent to make before that team performs a defensive action — a tackle, an interception, a foul, or a pressure. The lower the number, the higher and more aggressive the press. The higher the number, the deeper the team sits and the more space it concedes. The tournament average at the 2026 World Cup was around 13.2. Morocco's figure across the three knockout matches was 25.1 — nearly double the baseline. That number was not a statistical accident. It was the fingerprint of a system.

What I want to say right from here, before going into the detail, is a principle I remind myself of every time I open a data table: sitting deep does not mean being passive; it is a way of stretching the pitch in order to punish at the right moment. When people read a match through possession share, they easily forget that possession only measures time on the ball, not control of space. Across the three knockout matches, Morocco conceded an average of 71.6% possession — meaning the ball sat in their opponents' feet for almost three-quarters of the time. Yet across those three matches they conceded only one goal, while their opponents' combined xG reached just 4.02. When a team concedes nearly 72% possession and still keeps its goals-against at one, the thing that needs explaining is not luck. It is structure.

I spent many evenings redrawing Morocco's positional map across the knockout matches. Regragui's system operated as a mid-to-low defensive block, usually compacting around the middle third and the penalty area, with two lines of four that barely moved in terms of horizontal distance. Sofyan Amrabat played the anchor role in front of the back line, the man who swept up every pass that tried to pierce the gap between centre-back and full-back. Romain Saïss and Nayef Aguerd covered each other in a way where neither left his position before the other had locked down his zone. Achraf Hakimi and Noussair Mazraoui did not push up on impulse; they pushed up at the right moment, and dropped back at the right moment. It was a machine running on the discipline of distance.

What made that system different from an ordinary defensive block was that Morocco did not defend to survive. They defended to invite. When the opponent passed the ball around the middle third, the high PPDA was not because Morocco could not press, but because they chose not to press. They let Spain pass, and pass, and pass, until the ball was forced into a zone Morocco had already prepared. Every sideways pass in a harmless area was a pass with which the opponent was burning its own time. And for a team that knew it could not win a pure foot race, time running out was part of the victory.

The round-of-16 match against Spain is the clearest example. Morocco conceded around 77% possession; the opponent completed thousands of passes and controlled the game on paper. But Spain's total xG in that match reached only a modest level, because most of their passing happened in front of a closed defence. The match went to penalties, where Yassine Bounou became the hero, and Achraf Hakimi, a player born in Madrid, scored the decisive spot-kick with a cold panenka against the goal of the team he had once dreamed of playing for. Some symbols cannot be measured by data, but data can at least point to the conditions that let a symbol appear: Morocco dragged the match into exactly the window of time they wanted.

In the quarter-final against Portugal, the script repeated but with finer tuning. Morocco conceded around 73% possession. En-Nesyri scored with a leap in the 42nd minute, and what followed was nearly fifty minutes of defending with both heart and structure. Portugal poured the ball forward, Cristiano Ronaldo came off the bench, but every final ball ran into a wall that had been built in advance. Portugal's total xG in that match did not reflect the pressure the eye felt. That was when I learned an old lesson that is new every time: the feeling of pressure and the reality of pressure are two different things.

The turning point that made me trust my argument came from a smaller detail. In the semi-final against France, Morocco lost 0-2, and it was the only match in the knockout run in which they conceded two goals. But what stood out was that in the second half, Morocco pushed higher, held more of the ball, and created genuine chances — including one moment where, had the ball been a few centimetres lower, the picture might have changed. That shift itself showed me that Regragui's deep system was a conditional choice, not a helplessness. When the team needed to retreat, they retreated. When the team needed to push up, they pushed up. A team genuinely pinned back cannot freely change its posture at will. Morocco could.

There was another moment in that World Cup that I still keep in my head as a marker. In the match where Morocco were forced to push up in search of an equaliser, a shot hit the post. As the ball struck the woodwork and bounced out, I understood why I have always believed that moments like that should not be read as mere regret. Every shot that hits the post is a world not yet born. It reminds me that football operates on a thin line between system and luck, and the job of the data writer is to point out where that line lies, not to attribute to luck what belongs to structure.

Before going deeper into the data, I want to tell an older story to explain why I never begin an analysis with a feeling. In 2026, I was nineteen, a second-year student in Busan. On World Cup night, I entered all 23 of Germany's shots against South Korea into an xG model I had written in Python. The result appeared: Germany generated 1.32 xG but scored 0, and lost 0-2. Cross-referencing with the highlights, I realised the naked eye had been fooled: 18 of the 23 shots, or 78%, came from outside the box. On that night in Russia, I saw a number feel pain for the first time. But the bigger lesson lay elsewhere: a team can look like it is attacking relentlessly while in reality firing from hopeless distances.

That lesson came back intact when I analysed Morocco. If you look only at possession share, Morocco look like a team hemmed in for three matches. If you look at the xG map and PPDA, an entirely different picture appears. I asked myself the question I always ask before writing anything: where does this data come from, and how many matches is the sample? Three knockout matches is a small sample. I have to say that clearly. But three knockout matches at a World Cup, against three top opponents, is a sample with its own weight, because it is not a single anomalous match. It is a sequence.

Another year taught me that you must verify the foundation before building the upper floors. In 2026, K League 1 became one of the first leagues in the world to resume in empty stadiums. The xG model I had written in 2026 began to drift. I collected 152 matches and found the home win rate had fallen from 46.2% in the 2026 season to 31.6%. I completed a forty-page report concluding that every 10,000 spectators was worth roughly 0.08 expected goals for the home team. Nobody asked for that report. But I knew that if I did not fix the foundation, every later analysis would be wrong. The 0.08 coefficient does not measure the silence; it measures what we lost.

That very report led me to Morocco. In 2026, I was twenty-three, a new staff member at a newsroom. Thanks to the 2026 dossier, I was assigned to analyse the first African team to reach a World Cup semi-final. At the time, Korean media — the market I serve — viewed Morocco as an interesting but fragile phenomenon. I saw a system. And I wrote a sentence many people disputed: defending does not mean being passive.

To prove that, I had to do something I encourage every data analyst to do: publish the limitations of the model. PPDA has inherent weaknesses. It measures defensive actions, but does not distinguish a decisive tackle from a stray touch. It cannot measure the quality of the space left open, only the quantity of passes allowed. A team can achieve a low PPDA through a fiery press, or through an opponent that simply passes poorly. Conversely, a team can achieve a high PPDA because it chooses to concede, or because it simply cannot keep up. To distinguish those cases, I had to combine PPDA with the positional map and the quality-of-chance metric. Only when all three layers agreed would I let myself conclude.

At Morocco, the three layers agreed. PPDA 25.1 showed they did not press high. The positional map showed their defensive block kept near-perfect distances and was not stretched horizontally. And the quality of opponents' chances showed that most shots came from outside dangerous areas or under pressure. All three data layers pointed the same way. That was when I dared to write that Morocco were not being pinned back.

There is a sentence I always remind myself of: before talking about win or loss, I must ask the numbers first. But asking the numbers does not mean worshipping them. This is where I want to pause a little longer, because this is where most data analyses fail. They take one pretty metric, build it into a truth, and end the article with an assertion that cannot be wrong. I try to go the other way. Morocco's PPDA 25.1 is not a truth. It is one piece of evidence in a chain of evidence, and that chain only has value when I say clearly where it might break.

It might break here: three knockout matches is a small sample, and a penalty shootout can reverse the entire story within minutes. If Bounou had saved nothing in the shootout against Spain, Morocco would have left the tournament in the round of 16, and nobody would be writing about PPDA 25.1 at all. That is an uncomfortable truth every data analyst must admit: data describes probability, not destiny. Morocco's system raised their chances of going far, but did not guarantee it. And I will never write an analysis in which the final result is presented as inevitable.

This is also where I want to separate myself from a common habit in sports analysis: using data to retell a story whose ending is already known. When Morocco reached the semi-final, a wave of articles explained that they got there because of courage, because of spirit, because of the fire of an African team. Those articles are not wrong emotionally, but they explain nothing. Courage does not keep three clean sheets against three top teams. A correctly designed defensive system can. I chose to write about the second.

There is another dimension of the Morocco story I always want to include, and it concerns how data operates in the dressing room. In recent years, data analysts have been penetrating ever deeper into the space of coaches and players. They bring models, tables, and recommendations about standing positions, passing directions, pressing timing. That has value. But there is a trap: their conclusions are often detached from the actual rhythm of the match. A model can say you should press in the 60th minute, but it cannot feel the legs of a player who has run eleven kilometres. It can say you should keep your distances, but it cannot hear the breathing of the man beside you.

That is why I always try, in every article, to leave a place for what data cannot measure. With Morocco, that place is the story of a team from a country that had never passed the quarter-finals, under a domestic coach who was underestimated, playing the football the whole world calls defending, and reaching the seventh match of a World Cup. Data explains how they did it. Data cannot explain why it mattered. And a decent article needs both.

Now back to the number. What does PPDA 25.1 against a tournament average of 13.2 mean? It means that in a match, Morocco allowed their opponent nearly twice as many passes before performing a defensive action as an average team. In other words, they accepted letting the opponent hold the ball longer, pass more, and advance closer to the danger zone before intervening. This is a calculated choice, because a high press has a price: if you push up to win the ball, you leave behind you a space a long pass can exploit. Morocco did not have a back line fast enough to race against elite forwards. So they chose not to race.

Instead, they pulled the opponent into a spatial trap. By keeping the defensive block low and narrow, they turned the middle third into a corridor the ball could pass through but not stop in. The opponent was forced to choose between two bad options: a harmless sideways pass, or a forward pass into a zone where someone was waiting. And when the opponent chose the second, Morocco reacted. That is why their PPDA was high in harmless zones but low in dangerous ones. The aggregate metric cannot see that difference, but the positional map can.

This is the point I want to emphasise with a single image, because I believe each analysis should contain only one image that carries heat. Picture Morocco's defensive block as a fishing net. When the opponent passes the ball in the middle third, the net lets the water through. When the opponent tries to thread a ball into the box, the net closes. The water still flows, but the fish does not get through. That is Regragui's entire system, wrapped in one image.

Of course, a net only works if the threads are woven correctly. And those threads are people. Sofyan Amrabat was the central thread, the man who ran the most in the team, the man always present where the ball was about to arrive. Yassine Bounou in goal was the final thread, the man who turned a good system into an almost impenetrable one. Achraf Hakimi was the flexible thread, the man who could both defend and produce the decisive attacking moment. A tactical system, in the end, is just a way of organising people. Without the right people, it is only a diagram on a board.

There is another facet of the data I want to include, and it concerns timing. Across the three knockout matches, Morocco conceded one goal. That goal did not come from a beautiful combination by the opponent, but from a situation where the structure broke for an instant. This matters, because it shows Morocco's system was not an impregnable wall. It was a wall that could be breached if the opponent was patient enough and precise enough. And that is exactly what France did in the semi-final, scoring early and forcing Morocco to leave their comfort zone.

In other words, the weakness of a deep system is not in defence. It is in scoring. A deep team can hold out for a long time, but if it does not score, it depends on a single moment or on penalties. Morocco scored at exactly the moments they needed: a leap against Portugal, a shootout against Spain. But against France, when they fell behind, they were forced to push up, and in pushing up, their structure lost its greatest advantage. That is the structural tragedy of every deep team: they are strongest when they do not need to score, and weakest when they must.

This is where I want to offer the counter-intuitive angle of this article. Most people, looking at the 71.6% possession tilted toward the opponent, will conclude that Morocco were weaker. I think that conclusion is right in terms of resources but wrong in terms of tactics. In football, possession is a resource, not a goal. If you have more resources but do not know how to convert them into quality chances, having more resources does not help you win. Spain held 77% of the ball against Morocco and went home. Portugal held 73% and went home. Those are two examples of owning a resource without converting it into a result.

Here lies a logical trap I am always wary of: correlation is not causation. Morocco conceding a lot of possession and winning does not mean conceding a lot of possession causes winning. If a weak team concedes a lot of possession, they usually lose heavily, because they concede because they cannot do anything else. Morocco conceded because they chose to, and that is a difference of substance. To distinguish the two cases, I have to look at the quality of the defensive structure, not just the possession share. And Morocco's structural quality, measured by distance, by the number of quality chances they allowed, was on an entirely different level.

This leads me to a thought about how we read major tournaments. During a World Cup, national emotion runs high, and fans tend to look for simple heroic stories. They want to believe their team wins because of courage and loses because of bad luck. Data does not deny those things, but it forces us to put them in their place. Courage is part of the story, but courage does not build a defensive block that keeps its distances for ninety minutes. What builds that is hundreds of training sessions, video analysis sessions, a coach willing to choose a style that is unpopular with the majority.

And this is where I want to tell another story, a transfer-market story, because it shows how data operates in an entirely different environment. In 2026, I was twenty-five. The Morocco article helped me connect with a sports data company in Lisbon. From this source, I discovered a Korean midfielder at a mid-table club who had played only 564 minutes the previous season, far below the 1,200 minutes written into his contract. I sent his agent a six-page metrics report. On June 8, 2026, I was the first to reveal the loan deal with a 2.8 million euro buy option. The agent shared that they trusted me because I brought numerical evidence, not emotional judgement.

That story taught me that data can operate in two very different ways. On the pitch, it describes a tactical system. In the transfer market, it describes an asset. And in both cases, the principle holds: a transfer fee does not measure talent, it measures the buyer's desire. A player who has played 564 minutes can be undervalued not because he is poor, but because people have not looked closely enough. That is also what happened to Morocco: an undervalued team not because they were poor, but because people had not read their structure closely enough.

There is an intersection between these two stories I always want to write out. Both involve looking at what others overlook. With Morocco, it was PPDA 25.1 and the positional map. With that Korean player, it was the actual minutes played versus the minutes written into the contract. In both cases, the truth was not in the flashy numbers but in the forgotten ones. And the job of a data writer is to go find those forgotten numbers, and tell their story.

Now let me return to Morocco one last time, to draw something applicable to the future. Regragui's deep system is not a new invention. It is an old tradition, refined. The greatest teams in history have all used it at certain moments: counter-attacking defence, a low block, disciplined distances. What Morocco did differently was execute it at a rare level of organisation, in a tournament where most teams wanted to attack. And they did it while carrying the expectations of a whole continent that had never had a team reach a World Cup semi-final.

For me, the most memorable thing about that World Cup was not a goal, but a way of reading. That way of reading says that when a team concedes nearly three-quarters of possession, we should not rush to conclude they are being pinned back. We should open the data table, and ask where they are letting the opponent hold the ball. Because not every pass has the same value, and not every concession is a surrender.

I do not write about football. I write about the light that data illuminates. And that light, in Morocco's case, shines straight onto a truth modern football often forgets: defending, when executed with enough intelligence, can be a form of attack.

Before I finish, I want to be clear about my limits. Three knockout matches is a small sample. A penalty shootout can reverse any conclusion. I do not have access to Morocco's internal GPS data, to their training sessions, to the conversations in the dressing room. I only have what is public: pass counts, shot counts, positional maps, and metrics anyone can recalculate. That is a narrow foundation. But on that narrow foundation, one thing emerges fairly clearly: Regragui's system turned an underestimated team into one of the hardest teams to beat in the tournament. And that did not come from luck.

The next major tournament is coming. When it does, there will again be teams underestimated because of their possession share. There will again be articles calling them teams being pinned back. And there will again be data writers, sitting in front of a screen at three in the morning, opening the metrics table, and finding a number waiting to be explained. What I hope, after everything Morocco did, is that next time we will slow down one beat before branding a team passive. Because sometimes, the smartest way to defend is not to chase the ball. It is to let the ball come to where you want it to go.

When the final whistle of the semi-final blew and the Moroccan players sank to the turf in exhaustion, I closed the data table and sat still for a while. On the screen, the line PPDA 25.1 was still there. It would not change after this match. But the way I read it had changed. For the first time, I understood that a metric does not only measure a team. It measures the distance between what our eyes see and what is actually happening. And the job of the data writer, from start to finish, is to narrow that distance, one match at a time.
