Vietnam win the 2026 ASEAN Cup: Kim Sang-sik, Nguyễn Xuân Son, and the V.League's unanswered question

On January 5, 2026, at Rajamangala Stadium in Bangkok, I sat in front of a screen with a cup of coffee that had gone cold long before. Nguyễn Xuân Son had just put Vietnam ahead, and then he went down. Not from a malicious tackle. Just a running step, the kind a striker takes hundreds of times a match. Fibula and tibia. He tried to stand. He could not. The stretcher came, and the whole stadium went quiet — the kind of quiet I had heard once before, on a June night in Busan in 2026, when South Korea beat Germany. I bring up that moment not to make it more tragic. I bring it up because it is the strange intersection of everything Vietnamese football is carrying on its shoulders: a naturalized star, a Korean head coach, a regional tournament, and a football nation trying to find its footing — trying to find a sense of belonging. Vietnam won that match 3-2, won the tie 5-3 on aggregate, and lifted the trophy. But behind the floodlights of Rajamangala, there are questions still lying exactly where they were, waiting to be asked. To understand why this title carries weight, you have to go back to the spring of 2026. At that time, Vietnam under French coach Philippe Troussier had endured a dismal run in the second round of AFC qualifying for the 2026 World Cup. Two defeats to Indonesia — including a heavy loss on Jakarta soil — cost Troussier his job in March 2026. The larger consequence lay in the standings: Vietnam failed to get through the second round, failed to reach the third round — a stage the team had touched during the 2026 World Cup campaign. That was a shock in the truest sense. For more than a decade, Vietnamese football had built an identity: no longer a whipping boy in Southeast Asia, but a genuine force — a 2026 Asian Cup quarterfinalist, a 2026 AFF Cup champion under Park Hang-seo, a 2026 World Cup third-round qualifier. Then, suddenly, all those foundations shook at once. In May 2026, the Vietnam Football Federation appointed Kim Sang-sik. He is Korean, a former Jeonbuk Hyundai Motors coach, a name familiar to Asian football but one who had never worked in Southeast Asia. Choosing a Korean coach once again — after Park Hang-seo — showed that the VFF believes in a model: discipline, fitness, organization, and tactical humility. That belief has its reasons, because Park Hang-seo himself proved it here. But football does not repeat itself mechanically. Kim Sang-sik inherited a team losing its faith, with a misfiring attack, a defense that repeatedly made positional errors, and a golden generation — Nguyễn Quang Hải, Nguyễn Công Phượng, Nguyễn Tuấn Anh — moving down the far slope of its career. He had very little time before the 2026 ASEAN Cup kicked off in December. The regional picture was also shifting fast. Indonesia, under coach Shin Tae-yong, had pushed an ambitious naturalization strategy, bringing in a wave of Dutch-born players of Indonesian descent for the 2026 World Cup qualifiers. Thailand remained loyal to domestic development and academies. Vietnam, caught between those two paths, was searching for its own — and the 2026 ASEAN Cup was its first interim answer. Vietnam's run through the tournament unfolded almost perfectly: topping the group, then overcoming Singapore in the semifinal and Thailand in the final. But what stood out was not the results; it was how the team controlled its emotions. In matches that should have been nerve-wracking, they were strangely calm. And that calm, in my view, is the hardest thing to teach in football. The first thing Kim Sang-sik did was not on the tactics board. It was in how he spoke to his players. I was not in the dressing room; I only watched what happened on the pitch and read back the press conferences, but one change was unmistakable: Vietnam played like a team that knew what it wanted, instead of a team trying to do too many things at once. Under Troussier, the team tried to play a possession game it was not good enough to execute. Under Kim Sang-sik, the team accepted who it really was. Organizationally, he rebuilt the defense around three center-backs. This allowed the wing-backs to push high, turning the shape into a flexible block of three or five at the back. When they lost the ball, Vietnam quickly collapsed into a flat four, willingly conceding possession in harmless areas. When they had the ball, they looked to move it forward quickly to a target striker, letting the attacking midfielders follow. This is what I call football of organized endurance. It is not beautiful in the sense of one-touch passing, but it is effective in the sense of results. In Southeast Asia, where matches are usually decided by fitness, set pieces and cold-blooded finishing, effectiveness usually beats beauty. From what I recorded throughout the tournament, a pattern kept repeating: Vietnam tended to score in the second half, after wearing the opponent down. That is no accident. It is the product of a carefully prepared fitness plan, and of a team willing to start slowly and then accelerate at the right moment. I cannot be sure whether this was a deliberate philosophy or simply a consequence of the team not being confident enough to attack from the start, but the result was the same. At the center of that plan was a man few in Europe have ever heard of: Nguyễn Xuân Son. He was born in Brazil as Rafaelson Bezerra Fernandes, came to Vietnam to play, wore the shirt of Thép Xanh Nam Định, and became one of the best goalscorers in V.League 1. Then he was naturalized, becoming Vietnamese on paper, and becoming Vietnamese on the pitch in a way only goals can prove. There is a line I have always believed: some stars burn brightest only where they are loved, not where the lights are brightest. Nguyễn Xuân Son is an almost perfect example of that. In Brazil he was an ordinary player. In Vietnam he is a star. Not because he suddenly got better, but because he was placed exactly where he was needed. But it is here that the story opens a crack. That a national team must lean on a naturalized striker to solve its scoring problem is a confession. It confesses that the domestic youth system — after many years — still has not produced a striker of sufficient caliber. The Hoàng Anh Gia Lai academy, the PVF center, youth projects invested with millions of dollars, have produced many technical midfielders, but very few goalscorers of international standard. That is a paradox Vietnamese football has not solved. And this is where we must talk about V.League 1, the cradle that should be feeding the national team. The league runs on a model I have observed in many parts of Asia: dependence on benefactors. Some clubs live off one individual's pocketbook, rather than ticket sales, broadcast rights or commercial revenue. When the benefactor is enthusiastic, the club lives. When the benefactor tires, the club can vanish. This is a model that delivers short-term success but sows long-term instability. That model also shapes how clubs buy players. The transfer market is a stage where people buy stars and sell patience. V.League clubs tend to buy cheap foreign strikers — usually Brazilian or African — rather than patiently develop a Vietnamese striker for five years. It is a rational decision in the short term, but a disastrous one in the long term. And it explains why the national team, at the decisive moment, had to call on a naturalized man. The second paradox lies in the player-export pathway. In recent years, several Vietnamese players have tested themselves abroad: Nguyễn Công Phượng wore the shirt of Mito HollyHock in Japan, Nguyễn Tuấn Anh played for Yokohama FC, Nguyễn Văn Toàn went to Seoul E-Land in South Korea, Nguyễn Quang Hải tried his luck at Pau FC in France, Đoàn Văn Hậu went to SC Heerenveen in the Netherlands. Most of those journeys were brief and left little mark. Based on my experience watching matches, there is a tactical reason behind those failures. Vietnamese players are trained to shine in an environment where they are the center of the team — where the ball is delivered to their feet, where they are allowed to make mistakes. When they go to Europe or Japan, they become supporting actors, who must run off the ball, must duel, must wait for a chance. It is a role change many cannot survive. Not because they lack talent, but because they were never taught how to become part of a machine, rather than the center of it. I have watched a great many matches in Asia, and one thing always makes me stop: the way Vietnamese people love their national team. In a country where I — an exile — always ask myself where I belong, I see in them something I long for: the sense that a collective can represent something larger than itself. When the team wins, a whole country wins with it. When the team loses, a whole country grieves with it. That is football money cannot buy, and it is also something a regional title can temporarily mend. Back to the 2026 ASEAN Cup. Vietnam won, and no one can take that away. But read closely, and you see that victory was built on three pillars: a foreign coach who organizes well, a naturalized striker who scores, and a collective willing to play unglamorous football. All three pillars are stopgap solutions, not foundations. And that is what makes me think. Now comes the part where I might be wrong. There is another reading, far more optimistic. Perhaps the 2026 ASEAN Cup was not a stopgap but a turning point. A young team learned how to win, learned how to withstand pressure in a final, and, most importantly, learned that it can be champions without playing perfect football. That belief — a belief money cannot buy — could be the foundation for years to come. I may also be too pessimistic about the export pathway. A few Vietnamese players going to Japan, Korea or Europe, even in failure, still plant seeds: experience, professionalism, and a new standard in which going abroad is normal. Later generations will walk a road the earlier ones opened. And perhaps, most importantly, reliance on a naturalized striker is not a sign of weakness, but a sign of maturity. The strongest football nations all naturalize players. If Vietnam learns to integrate naturalized players without losing its identity, that is a step forward, not a step back. But I still cannot shake one question. When Nguyễn Xuân Son went down at Rajamangala, Vietnam lost its main scorer — and he will be out for a long time. If tomorrow another naturalized striker goes down, or is no longer there, then who will score? That is a question a title cannot answer. It is a question that lives in the V.League, in the academies, in the twelve-year-olds practising their shooting on some village pitch. I write against the wind, but my heart is never against football. Kim Sang-sik did what the very best coaches can do: he made a team believe in itself. But belief is a beginning, not an ending. The 2026 ASEAN Cup is a beautiful moment, and I do not want to diminish it. I only want to ask: if one day Vietnam were to win without a naturalized striker, without a foreign coach, and without having to play defensive football to survive — then what would we call that? I cannot be sure. But I want to live long enough to see that day.
