Vietnam face their biggest test: a 27-match unbeaten run meets Thailand

There was a moment in the press conference in Bandung that few noticed: Kim Sang Sik placed his hand on the table, looked directly at the Thai journalists, and said something that silenced the room for a few seconds. Essentially, that Thailand are strong in midfield, and that Vietnam have prepared for it. No promises, no challenges. Just a confirmation. That is how a coach tells an opponent he has read them, without needing to boast that he has read them. The match between Vietnam and Thailand in Group B will take place in a few days, and it is no longer merely a group-stage fixture. In the history of Southeast Asian football, Vietnam–Thailand confrontations have always carried a weight of their own. But this time, that weight is multiplied by a single number: 27 matches unbeaten. Twenty-three wins, four draws. A run so long it is no longer an achievement — it has become an identity. People now speak about Vietnam's national team by mentioning that record before mentioning anything else. And that is precisely when the danger begins. Vietnam's opening match at this tournament ended only 1-0 against the Philippines. A win, but a narrow one. Nobody says this aloud, because next to a 27-match unbeaten run, a 1-0 looks like an ordinary step. But look at how the match unfolded and you see a Vietnam that was not dominating — it was controlling. Those are two entirely different things. A dominating team creates chances; a controlling team creates silence. And Vietnam, under Kim Sang Sik, have become very good at creating silence. That is also the foundation for Kim's approach against Thailand. He speaks of a two-phase plan: the first half locking the shape, holding distances, keeping the door shut; the second half accelerating, pushing the line higher, exploiting the space behind the opposition defence. It sounds simple. But it is a heavily risk-managed approach. It trades early aggression for late control. And it depends on two things nobody can guarantee before kickoff: fitness, and the quality of those coming off the bench. The problem is that phase two — the phase Kim calls exploiting the space behind — is missing exactly the players capable of executing it. Nguyen Xuan Son is out for four to six weeks with injury. Quang Hai is absent. Van Vi and Thanh Chung are also missing from the squad. Hoang Duc remains doubtful. Four national-team pillars, plus a major question mark in central midfield, removed from the equation within days. In other words, Kim is drawing an attacking plan without his main pen. There is one small but telling detail in how Kim handled this shock. He publicly apologised to Vietnam's fans, and specifically to Thep Xanh Nam Dinh, for letting Xuan Son leave in national-team colours and return injured. This is something few national-team coaches would do, because it acknowledges an uncomfortable truth: in the Vietnamese football system, a V.League club losing its starting forward to national duty is a recurring risk, and the club receives nothing to offset that risk. That is not a national-team financial problem. It is a structural problem of an entire football ecosystem. But back to the match. Vietnam's opponent is Thailand, who just beat Pakistan 4-0 and rested Chanathip Songkrasin specifically for this game. That detail matters more than it appears. For a team to rest its most creative player in another fixture, saving him for one specific match, is a tactical statement. It means: we know which match matters most. And it means: we are aiming at you. The Thailand Vietnam are about to face is not the Thailand of the ASEAN Cup final reportedly played a month ago. That is the assessment of commentator Quang Huy, and it is sharp enough to remember. He says the current Thailand are more formidable than the side that lost to Vietnam in that final. A remark that both warns and respects. If Thailand lost the decisive match, and now return stronger, the question is not whether Vietnam can win — it is what price Vietnam will have to pay to win. What Thailand bring to this match is variation in how they score. They can win in different ways. That is a sentence worth reading slowly. In football, a team that knows only one way to win is easily decoded. A team that knows three ways is very hard to prepare for. And lessons from recent meetings show Thailand remain the side with the highest individual-creation capacity in the region, thanks to their technical midfield. That is precisely why Kim speaks about Thailand's midfield before anything else. What is interesting is how Kim responds to that threat. He does not talk about imposing the game. He talks about enduring it. That is a subtle shift in language. A team that imposes talks about controlling the ball, controlling tempo, controlling territory. A team that endures talks about holding distances, holding shape, and waiting for the moment. Quang Huy calls it quick transitions and tactical flexibility. I call it accepting a difficult first half. But this is where I want to pause a little longer. Because there is another way to read the 27-match unbeaten story, and that reading does not get much airtime in the press. A 27-match unbeaten run at national-team level is extraordinary. It does not just require a good team. It requires a good team over a long period, against many types of opponents, in many circumstances. No trophy is awarded for such a run, but it creates something more valuable than a trophy: it creates expectation. And expectation, in football, is a debt. When you are unbeaten in 27, every next match is no longer an opportunity to win. It becomes a risk of losing something you have painstakingly built. That psychology seeps into players, coaches, and fans alike. It turns a draw into a defeat, and a defeat into a crisis. This is why long runs often end not at the hardest place, but at the most unexpected one. Because the burden of sustaining is not about the quality of the opponent, but about the weight of the expectation itself. There were seventeen passes strung together before a goal that the whole world missed, and I learned that football's collective memory only records the final ball. We remember the shooter, not the one before him. We remember the scoreline, not how it was made. And in Vietnam's case, we remember 27 without remembering that many of those were narrow wins, matches in which the team had to patiently endure before finding the goal. A 1-0 is no less valuable than a 4-0. But it tells a different story about the team. It tells of a team that knows how to win without standing out. That is a rare skill. But it is also a skill easily misread. And this is where I want to offer another angle — one I think we should consider before entering this match. Usually, people read an unbeaten run as an advantage. The team is used to not losing, so it does not fear losing. Players trust the system, so they do not panic when behind. That is the positive reading, and it is partly right. But there is an inverse reading: an unbeaten run turns every match into a defence of honour rather than an attack on opportunity. The team walks onto the pitch with the goal of not losing before the goal of winning. And when you walk out with the goal of not losing, you choose safer options, lower-risk passes, less ambitious forward surges. You do not play to win. You play not to lose. And in a match against an equal opponent, that is a huge difference. This is the crux I think the press has not explored enough. Vietnam enter the Thailand game with an attack missing players, an unbeaten run creating pressure, and an opponent who is fully rested plus motivated by revenge. Those three factors combined do not produce a favourable picture. They produce a picture in which luck and individual character will have to carry more than the system. And in football, when the system must give way to individual character, results become far harder to predict. There is one thing I have always believed while watching matches at this level: a mistake is not a full stop, it is only a comma, and the story continues on the next page. That is true for both sides. For Vietnam, a defeat to Thailand would not erase 27 unbeaten matches, nor a regional title. It would simply move the story to another chapter — one about how this team responds when, for the first time in a long while, they face the truth that they can lose. For Thailand, another defeat to Vietnam would be a deeper cut, because it would confirm something Thai football is trying to deny: that their regional number-one status has been challenged systematically, not incidentally. Before kickoff, people often ask me who I think will win. And I usually avoid the question, not because I have no opinion, but because I think it is a less interesting question than another one. What is worth watching in this match is not which team scores more. What is worth watching is which team forces the opponent to play their way. Vietnam want Thailand to push high so there is space behind. Thailand want Vietnam to drop deep so their midfield has time and space. Whoever imposes their tempo in the first twenty minutes of the second half controls the match. And those twenty minutes, to me, are the most worth-watching stretch of the whole game. As for the young players who will be given a chance, this is a bright spot I think deserves more mention. Williams Minh Hoang, nineteen, an overseas-Vietnamese player, came on and assisted a goal for Dinh Bac. It was a small moment but with large meaning. It shows that while the national team loses pillars, the door is opening for the young, and at least one of them has walked through it. Nothing guarantees Minh Hoang will shine against Thailand. But his emergence, alongside names like Hoang Hen, Patrik Le Giang, Adou Minh, Cao Quang Vinh, and Ngo Dang Khoa, shows something notable about Vietnamese football: the resource base is widening. No longer only players developed domestically, but an entire layer of overseas-Vietnamese and naturalized players, scouted from all over the world. This is a structural change, not a stopgap. And it carries implications deeper than what is usually discussed. When a national team widens its resource base beyond national borders, it does not just increase squad depth. It changes how the team must manage the dressing room, how the coach must balance groups of players with different starting points, and how fans must redefine their sense of belonging to the national team. Those seeing an overseas-Vietnamese player in national colours for the first time may feel something unfamiliar. But modern football has proven this is the path most countries with large diaspora populations must walk. The question is not whether to do it. It is how to do it while keeping an identity intact as you expand the resource base. And this is where I think Vietnamese football is a step ahead of the region. The fact that overseas-Vietnamese and naturalized players are not just called up but used in important matches shows confidence in a scouting system that has been established, not an improvised reaction to an injury crisis. That is a sign of maturity. People do not remember a match for its scoreline. They remember it for how a team stood up. And what I want to see in this match is not a pretty score. What I want to see is how Vietnam respond when Thailand make it hard, when their midfield controls the ball, when Chanathip appears in a space that seemed non-existent, when Vietnam's defence has to endure a quick counter. Those moments will say more than any number about what Vietnam currently are as a team. A team that lives on the memory of past wins, or a team that lives on the ability to adapt to matches that have never happened before. There is a sound of silence in a crowded stadium, and it rings louder than any roar. I go to the ground to listen, not just to watch. And I will listen to this match very carefully. Not to find out who wins. But to understand whether, after 27 unbeaten matches, this Vietnam team still keeps the share of a team hungry to win — and how much of a team afraid of losing what it has. The match will end after ninety minutes, perhaps one hundred and twenty, perhaps a penalty shootout. But the poem about this team is still unfinished, and the next chapter will be written by how they walk into the Thailand match — not by the result, but by the attitude. That is what is worth waiting for.
