Kevin Diks, Mitchell Baker, Luke Vickery: Indonesia's Naturalization Gamble Ahead of the 2026 ASEAN Cup

On the afternoon of September 22, 2026, in the press room at Madya Gelora Bung Karno, Kevin Diks sat slightly to the left of the microphone. Watching the footage back later, I noticed something small: he placed both hands on the white plastic table, then withdrew his left, leaving the right resting still. For the better part of half an hour, that hand barely moved.

Asked about Mitchell Baker and Luke Vickery, Diks said the two players had sound ball skills and a strong mentality. He used the word "attitude" three times in a single answer. But the line that stopped me sat in the middle of the passage: the pair had trained with the Indonesia squad "before they could play for Indonesia". Diks said it in a flat tone, as if describing a morning session. Behind that sentence lay a closed paperwork file, a deadline already counted, and an armband that, by his own phrasing, does not belong to him.

Three days after that press conference, on September 25, 2026, Indonesia open the 2026 ASEAN Cup at home against Singapore.

Jay Idzes, Indonesia's actual captain, is absent through injury. The on-field leadership falls to Diks, a 29-year-old who plays for Borussia Mönchengladbach in the Bundesliga. Over the past four years, Indonesian football has run a systematic naturalization programme: finding players of Indonesian heritage raised in Europe, persuading them to represent the national team, and bringing them in during short international windows. Diks, Idzes, Baker and Vickery all sit inside that current.

One thing should be said plainly from the start: Diks's remarks contain not a single tactical detail. No formation, no pressing scheme, no defined role for Baker or Vickery in John Herdman's system. This was a pre-tournament media session, where a captain's job is to broadcast a message of unity. And that message, read closely, is about the speed of integration rather than the quality of the football.

The interesting layer sits in the cost structure underneath. Naturalization does not pass through the transfer channel. No fee is paid to any club. Resources shift from the transfer budget into administrative, legal and intermediary arrangements — items that barely register on any financial-control ledger. For a Southeast Asian federation, this is a way to compress national-team building without waiting for a generation of academy graduates. The price is not paid in money but in integration time, and time cannot be bought with any file.

Having followed Southeast Asian football from London for many years, I have noticed that federations in the region tend to choose one of two roads. The first is development: build academies, fund youth leagues, wait ten years. The second is naturalization: find players already formed elsewhere, cutting the timeline to three or four years. Vietnam has walked the first road fairly consistently, despite the occasional individual naturalization. Indonesia, under Herdman, has chosen the second with far greater concentration — and chosen it in a tournament staged at home.

The regional structure deserves to sit beside this story. In Southeast Asia, Indonesia, Thailand and Vietnam are usually placed in the leading group, with Malaysia and the Philippines behind. Indonesia is the only side in that leading group to make naturalization its spine rather than a supplement. That creates a difference in kind, beyond a difference in degree. When a team makes naturalized players its backbone, the way it plays, the way it speaks, and the way its audience sees it all shift accordingly.

Looking at the three times Diks said "attitude", a logic emerges. Speed of integration, not quality, is the decisive variable of the naturalization model. For a player born and raised in Europe, the problem is never technique — that has been verified in European league football. The problem is whether he will accept a different system, a different style, a different coach, inside a window of a few weeks. Diks said Baker and Vickery are "open to input", "humble", and that "adaptation to John Herdman's squad ran very smoothly". Those three adjectives say nothing about a left foot or a finishing touch. They speak about the capacity to listen.

And this is where the data goes quiet. No metric measures whether a player understands how his team-mates move when the ball is lost, or knows who will cover when a full-back pushes high. Those things only surface across real matches. The rhythm of a game can only be heard when you put your ear to the turf.

Tactically, there is a reasonable but unconfirmed inference. The phrase "new firepower" that Diks attached to the two newcomers suggests they are earmarked for advanced or creative roles. Meanwhile, Indonesia's defensive spine remains anchored by Europe-based players: Diks, and normally Idzes. If that inference holds, Indonesia's squad-building model has a clear shape — a European-standard defence, reinforced by new attacking inputs — and it places the organisational burden precisely on the axis that is currently short of men.

On the procedural side, FIFA's rules on international eligibility, covering nationality provisions and the one-time association switch, are the mechanism that allows cases like Baker and Vickery to exist. The line "before they could play for Indonesia" indicates the file is complete. That is a compliance signal, not a footballing one. It says the paperwork is done, not that the player is ready.

On September 25, the opponent is Singapore. An opening fixture at home, against a lower-rated rival, is the kind of match in which sides labelled title favourites routinely make life difficult for themselves. Diks seems aware of it: he spoke about keeping "both feet on the ground" and not underestimating Singapore. He also said the team's target is the title. Those two statements sit side by side in the same press conference, and the distance between them is the whole story.

Most reports will focus on the two new names. I keep thinking that the most important person in that room was the one who was not there. The loudest applause does not come from the stands, but from the empty seats.

There is a counter-intuitive reading. The arrival of Baker and Vickery does not say how much stronger Indonesia have become. It says Indonesia are accepting a specific risk: betting on the integration speed of men who have never played a competitive match for the national team, in a short tournament, at home, with a publicly declared title target. Luzhniki taught me that every move begins with a bad touch — and here, the first bad touch might be a cover run half a beat late, a pass into empty space.

The problem with the naturalization model is not level. It is latency. A player needs time to learn how his team-mates move when possession is lost, who drops to cover, what a shout in the dressing room actually means. Three weeks is not enough for any of it. What three weeks can buy is attitude — and attitude is exactly what Diks is selling to the media, using the personal credibility of a Bundesliga player.

A captain's praise at a press conference is the weakest form of evidence in any category. Football has a ritual: the captain protects the newcomer, the newcomer says nothing, the media repeats the compliment, and expectations are raised before a single minute has been played. If Baker and Vickery start slowly, those very compliments will return as the yardstick against which they are judged.

The empty months of stands taught me that football is a conversation, not a monologue. A press conference is the same. People only hear the answers, but the questions and the silences between answers are where the real information sits.

There is another layer to this story, an industry one. The naturalization wave creates a clear set of beneficiaries: intermediary networks and agents who connect players to federations and handle the paperwork. It also applies quiet pressure on domestic academies. When short-term results can be achieved by importing already-formed players, the incentive to invest in youth development weakens. That is a trade-off recorded in no contract, but it exists.

I still keep the habit from those empty months at Brentford: noting what supporters say, rather than only what the coaching staff say. With Indonesian football right now, supporters stand before two emotional roads. One is the belief that the national team has been upgraded and that the title is a reasonable target. The other is the worry that the team is slowly losing its identity and becoming an assembled collection of names. Both feelings have foundations, and both will be tested within weeks.

As for Diks, at 29 he is at his peak and simultaneously at the edge of the post-peak phase. In a short tournament, his role reaches beyond that of a defender. He is the man holding the defensive order, the spokesman, and the figure standing between the squad and outside pressure. That load is visible through a single detail: a right hand resting motionless on the table throughout the press conference.

The thing to watch against Singapore is whether an Indonesian defence missing its real captain can hold its distances and its order through the first twenty minutes. If it can, Indonesia's naturalization model has proven the hardest point of all: that it produces a team rather than a collection of good players. If it cannot, we will hear the word "attitude" again — and this time, not from a captain protecting a team-mate, but from a coach searching for an explanation.
