Pumas UNAM and the Guadalajara Nightmare: When 36 Years of History Weigh on an Unfinished Project

From the balcony of an old press box, I hear the derby echo through layers of memory. Every time Pumas UNAM prepares to march to Guadalajara, Juan Ignacio Dinenno lying on the pitch in the 2026 Liga MX semifinal flashes before my eyes. That is the moment I call "the geology of collapse" - not the fall that decides fate, but the sediment that had been paved long before.

Pumas are about to play two consecutive away matches against Chivas and then Atlas. Two trips, two opponents, one city. And a history long enough to make anyone who loves this club hold their breath.

36 years - a number that is not just a number

In 2026, Pumas beat Chivas at Estadio Akron. It was the first time in 36 years they had done so away against this opponent. I still remember how Mexican media reported it that day - as if a curse had been lifted. But the point is: one win does not erase 36 years. It only proves that 36 years is a fact, not a myth.

What does that number mean? For a big club like Pumas - a former champion, a producer of generations of excellent Mexican players - it means a kind of collective wound. Not the wound of losing, but the wound of never being allowed to believe you can win. When a team walks into an away stadium with 36 years of failure already embedded in its subconscious, every play takes on a different color.

And Atlas? Pumas have not beaten Atlas since 2026. That year, precisely, was the year of the controversial semifinal. There is a red thread linking these two numbers: both revolve around one city, one land where Pumas cannot find their way home.

What is striking is that the 36-year figure is no secret to anyone inside Pumas. Players know it. The coaching staff knows it. Opponents know it. When a statistic becomes common knowledge, it stops being a statistic - it becomes expectation, prejudice, a kind of invisible pressure that cannot be measured in xG or PPDA.

Context: two clubs building, one club dreaming

Chivas and Atlas - as Mexican media describes them - are two clubs competing for the title. They have squads and projects built to aim for the top. Atlas recently added Elías Montiel and Kevin Zenón, signings that signal clear ambition. Montiel - a young midfielder - and Zenón - a winger - are not random additions. They are pieces for a possession-based game, attacking down both flanks, creating chances through deliberate combinations.

Meanwhile, Pumas enter this trip with a project described as "under construction" under coach Esteban Solari. The phrase "under construction" in football usually carries a double meaning: on one hand, it acknowledges that short-term results are not an absolute priority; on the other, it is an excuse with an expiration date. No project is allowed to be "under construction" forever.

Solari - Argentine, younger brother of Santiago Solari - took over Pumas with the club needing a rebuild. He does not have a mandate to win the title immediately, but he needs to show progress. And Guadalajara is one of the harshest measuring sticks any Pumas coach must face.

Before this trip, Pumas beat León. That is a positive signal, a dose of psychological dopamine before entering hell. But as I often told colleagues in the old newsroom: a win makes you forget the problem, it does not solve the problem. Pumas's problem in Guadalajara was never form - it is structure.

Where is that structure? It lies in the fact that Pumas, in terms of squad quality, do not have enough to face directly two clubs built to win titles on their own turf. In transfer market terms, Pumas is a "selling club" - where young talents are nurtured and then transferred to clubs able to pay more. Chivas and Atlas are "buying clubs", ready to invest to close quality gaps. Those are two different business models, and the difference shows most clearly on the road.

I once wrote about how player agents become the biggest hidden cost in the transfer market - the noise they create distorts the true value of players. But in Pumas's case, the problem is not the agents. The problem is building a project on land where opponents have already finished their buildings. That is uncompetitive.

The absent name and the tactical gap

César Huerta will not play against Chivas. He may return for the Atlas match. That is the most important information before this trip, and it is not simply "a player absent".

Huerta is Pumas's most dangerous attacking player. He is the creator of moments - something in modern football sometimes more precious than a system. Without Huerta, Pumas lose their ability to transition. Without a reliable counter-attacking trigger, the team is forced deeper, the defensive block gets heavier, and the chances created from transitions drop to near zero.

Tactically, this means Solari may have to abandon the familiar 4-3-3 for a lower, more compact 4-4-2. But here is the trap: when you defend deep against a team like Chivas - capable of dominating possession and attacking down both flanks - you put yourself in a passive position. The ball will come, and it will come a lot.

People call that tactics; I call it the team's breathing rhythm on the pitch. Pumas's breathing rhythm without Huerta is the rhythm of a long-distance runner trying to swim. They know how to survive, but they do not know how to create.

Álvaro Angulo may also return for the Atlas match. That is good news, but it arrives too late for the more important first match. In football, the timing of a return is sometimes as important as the quality of the return.

As for the opponent's squad in the Atlas match, the additions of Montiel and Zenón pose a specific challenge for Pumas's flanks. Montiel can move the ball quickly in midfield, stretching the opponent's shape and creating space for wide attackers. Zenón, with pace and 1v1 dribbling, can put Pumas's full-backs in uncomfortable situations. If Pumas defend by compacting, they will face crosses from both flanks - where Mexican teams are always dangerous in set pieces. And set pieces, as all Mexican football statistics show, are where away teams suffer disproportionate losses.

The 2026 wound: when memory weighs more than points

The 2026 Liga MX semifinal between Pumas and Atlas is one of the most painful memories for Pumas fans of the past decade. Dinenno fell in the box. The referee did not award a penalty. If that penalty had been given, Pumas could have reached the final. Could have. Could have. Those two words are always the most toxic in football.

I have sat in press boxes that no longer exist, to write about matches that never grow old. And that 2026 semifinal, with all the injustice Pumas fans felt, will never grow old. It lives in collective memory, in coffee-table conversations, in midnight tweets. It lives in Dinenno's head.

This creates a complex psychological layer for the upcoming Atlas match. This is no longer a three-point match. This is a chance to repair something that cannot be repaired. And in football, when you walk onto the pitch intending to repair the past, you usually lose in the present.

Dinenno is a good striker. But he is also a human being. And humans, when haunted by a memory, often make emotional decisions. A reckless tackle, an unnecessary yellow card, a shot when a teammate is in a better position. Those small things can shape an entire match.

Solari will have to manage Dinenno's psychology no less than the team's tactics. Sometimes, a coach's job is not to draw up a formation, but to tell a player: "Forget it. This match owes you nothing."

I once witnessed something similar in a Merseyside derby at Anfield. An elderly supporter in the third row cried like a child over a goal that was not his. I understood that football does not only happen on the pitch. It happens in the minds of those who believe a single match can erase years of pain. That belief can be fuel, or poison.

A different angle: is the "nightmare" really a nightmare?

I want to ask a question. Are we being too generous with the story that "Pumas fear Guadalajara"?

36 years without beating Chivas away is a frightening number. But 36 years is long enough for many generations of players, many coaching cycles, many presidential eras. The current Pumas players did not live in those 36 years. They are not victims of history. They are those who write history forward.

Pumas's problem in Guadalajara, the way I see it, is not fear. It is a relative squad quality problem. When you face a team of higher quality, built to be champions, and you play in their stadium, losing is not strange. It is logic.

If we call it a "nightmare", we place Pumas in the victim position. But Pumas are not victims. They are a club trying to build something new. And sometimes, to build, you must accept that you will lose during the building process.

I do not believe Pumas enter this trip with fear. I believe they enter with humility. Humility is not knowing you are wrong, but learning the correct name of another. And in this case, humility is understanding that Chivas and Atlas deserve respect for what they are building, not for what Pumas has not yet achieved.

What I want to emphasize here is the difference between the media story and tactical reality. Media wants a story - and the story of a club haunted by history is always more attractive than the story of a club simply weaker in squad. But the truth, based on my match-watching experience, is usually the latter. Pumas do not fear Guadalajara. Pumas are simply not strong enough to go there and win comfortably. Framing a quality gap as psychological fear is a simplification that football does not deserve.

Opportunity in disadvantage

If I were Solari, I would tell my players one simple thing: "No one expects us to win here. So let us play like people with nothing to lose."

When there is no expectation, pressure disappears. And when pressure disappears, football becomes simpler. Pumas can play disciplined defense, exploit set pieces, and hope for a moment of luck. This style is not beautiful, but it is practical. And in football, practicality sometimes matters more than beauty.

I once followed Southport FC - a semi-professional club in the Merseyside area - during the days of empty stadiums due to the pandemic. I learned one thing: small clubs do not live by winning. They live by surviving. And in survival, there is a kind of dignity that winning sometimes does not have.

Pumas are not a small club. But in these two matches, they are David against two Goliaths. And like every David, they need a strategy, a belief, and a bit of luck.

There is another undermentioned aspect: this trip may be an opportunity for Solari to explore new tactical options without heavy result pressure. When you are not expected to win, you can try things you have never tried. A new formation, a young player, a different pressing approach. In football, experiments are sometimes the seeds of future success.

On the future of the Solari project

The most important thing in the Guadalajara trip is not the points. The most important thing is evidence of progress.

If Pumas lose both matches but show a clear tactical structure - organized defending, a small counter-attacking signal, collective cohesion - then Solari's project still has a chance. If Pumas lose both matches and look like a team with no ideas, then questions about Solari's future will begin to be asked.

In modern football, a coach is not judged only by results. He is judged by process. And Pumas's process under Solari is still an unfinished story.

The difference between Chivas, Atlas and Pumas lies in resources. Chivas and Atlas can buy top players. Pumas must develop them. Pumas's academy has a tradition of producing great talents, but retaining them is another story. In the model of a selling club, success is measured by youth development and transfer value, not only by points in the table.

That means, in the long term, the Guadalajara trip may matter more for Pumas's young players than the immediate result. A 20-year-old defender playing 90 minutes against Chivas at Estadio Akron will learn more than any training session. That is a value that cannot be measured in points.

What awaits ahead

This trip may shape Pumas's season. Two matches, six maximum points, but more realistically zero or one. In that context, every point gained is a small victory. And every point not gained is a lesson - if you know how to learn.

What I care about is not the result. What I care about is how Pumas face the challenge. Will they play with resignation or determination? Will they let history decide the match, or will they write a new chapter?

The ball rolls through time, but derby night memories roll through the heart. And in the heart of every Pumas fan right now, perhaps two parallel emotions coexist: the fear of the past and the hope of the future.

Every dynasty has a moment of leaving the pitch that no one notices; the perceptive will record that moment. If Pumas can find that moment in the two Guadalajara matches - a moment not of victory, but of progress - then this trip will not be a nightmare. It will be a milestone.

If not, they will return home with 36 years still on their shoulders, and a bigger question: is Solari's project heading in the right direction, or just trying to build a tower on already cracked ground?

That is a question no statistic can answer for them. And that is also why we sit here, waiting for two matches in Guadalajara - not to see who wins, but to see who will be the first to change the story.
