Indonesia Opens FIFA ASEAN Cup 2026: Herdman Bets a Patched-Up Defense on a Debutant

On opening night I sat in row twelve of the east stand at Gelora Bung Karno. My eyes were not on Agnes Monica or Isyana Sarasvati. Before the referee blew his whistle I had already spotted John Herdman on the touchline, team sheet in hand, eyes fixed on his back line. Four names: Kevin Diks, Elkan Baggott, Justin Hubner — and Luke Vickery. No Jay Idzes. That was the detail that made me sit up. Matches are decided where the crowd is not looking, and tonight that place was the gap beside Baggott. FIFA ASEAN Cup 2026 opened in Jakarta. A new name, a new structure — Group A Division 1 — and an elaborate ceremony. FIFA Secretary General Mattias Grafström was present. PSSI Chairman Erick Thohir stood beside him. Former internationals Kurniawan Dwi Yulianto and Ponaryo Astaman of Indonesia, Safiq Rahim of Malaysia and Baihakki Khaizan of Singapore sat in a row. The stage was built as a miniature echo of the World Cup opening ceremony. I understand why Indonesia wants that — they want the world to see them as more than just a Southeast Asian football nation. The trophy was handed over under the lights, and applause filled the stadium. Behind the ceremony sat a question nobody asked on stage: does a FIFA-badged competition actually change the quality of Southeast Asian football, or only the way it is sold? But I came to the stadium to watch football, not fireworks. What I saw when Herdman announced his line-up was a gamble. Maarten Paes in goal. Ahead of him Diks, Baggott, Hubner, Vickery. Above them Mitchell Baker, Ole Romeny, Ragnar Oratmangoen. Read the list and the model is obvious: almost entirely diaspora players — men born or raised in Europe, recruited by Indonesia through its naturalisation programme. This is not a national team built from the domestic league. This is a globalisation project. The problem lies elsewhere. With Idzes absent, Herdman did not replace one centre-back with another. He replaced one with a debutant who has never played a competitive match at this level. Luke Vickery stepped in, and the whole back line had to reorganise around him. That is a detail capable of ruining an opening match. Football is not a game of pretty names on paper. It is a game of the distances between passes, of the footfall rhythm of the man beside you. A new centre-back needs three or four matches to learn how his partner moves when the ball is on the left, when the opposition counter-attacks. Vickery does not have those three matches. He has one evening in front of eighty thousand home fans. Eighty thousand people in the stands did not see that. They watched the ball. I watched the gap between Baggott and Vickery. Southeast Asian football is shifting. Ten years ago a team like Indonesia was built from players raised in the domestic league, and their ceiling was the ceiling of that league. Now they have a talent pipeline from the Netherlands, Belgium and England. That is a genuine structural step forward. But a pipeline does not automatically produce a team. It only produces raw material. I have followed Indonesia long enough to know how the diaspora model works. It brings squad depth, pace and individual technique at European level. Data takes me to the stadium gate, my eyes take me into the dressing room — and in the dressing room what decides is not a passport but understanding. A team with eleven good players who have trained together for only a few days is a team that a more modest opponent can drag into a tight, suffocating contest. Singapore understands that. They did not come to Jakarta to perform. Baihakki Khaizan sat in the stands, but the spirit of his generation lives in the way this team chooses to play: a deep defensive block, closing the space behind, waiting for a mistake. If there is one position most prone to error in a patched-up back line, it is a new centre-back beside a partner out of sync. Baggott and Hubner are both physically strong, but neither has played alongside the other long enough to form a settled international pairing. Herdman is betting that individual quality will compensate for a lack of cohesion. In the first half, if Singapore plays long balls into the space between the two centre-backs, Herdman will have to adjust from the bench. And sometimes an adjustment comes too late. I am not sure that happens in an opening match. This is where I have to say what many in Jakarta will not want to hear. The story of an Indonesia side full of diaspora stars, backed by FIFA, opening a regional tournament with a lavish ceremony — that story is beautiful. But it can hide a structural weakness: this team is built to win, not yet built to endure. A shocking opinion is only worth something when it stands on a detail others overlook. The detail I nearly overlooked all evening was Singapore being described as a known quantity. That familiarity is a trap. When you think you know your opponent, you prepare for the match you imagine is coming, not the match that actually comes. Herdman's Indonesia does not yet have enough competitive data to know how it reacts when it falls behind in the fifteenth minute — entirely possible if Vickery is one beat out of step. Another angle, perhaps a hotter one: the name FIFA ASEAN Cup and the Division 1 structure are new. I checked the schedule and found a contradiction — the opening ceremony is listed on the 25th, while the Indonesia versus Singapore match is listed on the 26th. Both cannot be the same Friday. A small detail, but for someone in my trade it says this tournament is still taking shape, and the numbers around it are not yet worth blind trust. People laughed at me for three months, but laughter never scores a goal. Indonesia will beat Singapore. The individual quality of Baker, Romeny and Oratmangoen is enough to produce at least two goals. But I also believe they will concede at least once, and that goal will come from the area Herdman is betting on: a patched-up defence around a debutant. The thing to watch is not the final score. It is whether Jay Idzes returns before the knockout rounds. If he is out longer than expected, Indonesia can go far on the strength of its attack — but that road will be far steeper than the glitter of opening night suggests.
