Bae Ji-won and the Warning Bell: Vietnam Lost Its Weapon Against Thailand

In the tenth minute, Sarach Yooyen dropped back to receive the ball roughly twenty-five metres from Van Lam's goal. Not a single Vietnamese midfielder stepped out in time. The shot travelled like a drawn line, cutting through the red shirts and burying itself in the top corner. I sat in front of the screen, pen in hand, and wrote a single line in my notebook: this goal did not come from an individual error, it came from a designed gap.

The Si Jalak Harupat Stadium in Bandung, Indonesia, has never been a place Vietnamese fans dream about. But it was where the FIFA ASEAN Cup 2026 placed the match between two teams that have built the fiercest rivalry in Southeast Asian football. Exactly thirty-four days earlier, Vietnam under coach Kim Sang-sik had been crowned champions. That night I wrote, sleepless, that Vietnamese football had reached a new height. Tonight I have to write again, in a different voice.

The score was 0-2. Not heavy. But enough for analyst Bae Ji-won, who spent two decades in the coaching setups of several Korean clubs and has tracked Asian football ever since, to say something that made many sit up. Vietnam revealed many problems.

I spent three days rewatching the footage of this match, pausing on every passage Bae mentioned. Drawing on my years of watching matches, here is what I saw.

Thirty-four days between two peaks

To understand why this defeat means more than one match, we need to place it in the exact time frame in which it occurred.

On the twenty-sixth of August, Vietnam and Thailand drew 2-2 in the ASEAN Cup final. Vietnam took the title. A historic night, with throats torn raw from Hanoi to Saigon, with status updates shared tens of thousands of times. I sat in a small cafe in Guangzhou, listening to the cheers echoing through the phone from a friend in Hai Phong.

Thirty-four days later, the two teams met again. It was the first reunion since the final, and it came too soon. There was no real time to rest. No time to digest the victory.

On the touchline, Kim Sang-sik faced Anthony Hudson, who had just reshaped the Thai national team in a more pragmatic direction. While Thai public opinion was still debating Hudson's style, Hudson himself had understood one thing clearly: in Southeast Asian football, results matter more than beauty.

On Vietnam's side, the injury list read like a verdict. Nguyen Thanh Chung, Nguyen Quang Hai, Nguyen Xuan Son and Nguyen Hoang Duc, four pillars, were all struggling with injuries caused by a dense schedule over a short period. Hoang Duc still played and still produced notable bursts, but he was clearly not himself.

This is the context any analysis must respect. A team that had just reached a mental and physical peak, missing four pillars through overload, facing an opponent hungry for revenge. Those three factors combined into a puzzle with almost no perfect solution.

Is possession an advantage

Bae Ji-won used a phrase I believe is the key to the whole problem: imposing football.

It is a phrase Vietnamese football has heard for years but has never truly mastered. Imposing does not mean holding the ball a lot. Imposing means holding the ball in a way that forces the opponent to react, to break structure, to make mistakes.

In this match, Vietnam held more of the ball. But there is a detail that the stat sheet never shows: in the first half, there was a long stretch in which Thailand's back line stood almost perfectly still. Their central midfield trio, names with hundreds of international caps, moved as one block. They sealed the central corridors, the very lanes Hoang Duc's through balls usually travel through.

Bae said that holding a lot of the ball is not an advantage for Vietnam's current players. I agree, but I want to push that one step further. The problem is not that Vietnamese players cannot hold the ball. The problem is that when they have to hold it against an already-organised defence, they do not have enough options to create chaos.

Take Ngo Dang Khoa. This fast player is a sharp knife, but a knife is only useful when there is space to run into. When Thailand parked the bus in front of goal, Dang Khoa's speed became a weapon locked in its sheath. He needs space behind the defence, and Thailand gave none.

What is interesting is that Thailand chose this approach deliberately. They scored early in the tenth minute and immediately shifted their mentality: from a team wanting to attack to a team wanting to defend. This was a match-level tactical decision, and it showed that Hudson and his players understood the state of the game very clearly.

An early goal, a deep defensive line, and an opponent desperate to equalise. Those three factors combined into a trap that Vietnam walked into with full confidence.

I once witnessed a similar trap, in a different context. In 2026, at the Russia World Cup, I sat in the studio of a simulation programme and mispronounced Kylian Mbappe's name three times. The lesson I took was not about pronunciation. It was this: when you are not prepared enough for a situation, you react one beat late. One beat. And in football, one beat is enough to lose.

Vietnam reacted one beat late in this match. Not as individuals, but as a collective.

Individual moments and their limits

Bae mentioned what he called potential attacking solutions. In the thirty-seventh minute, Nguyen Tai Loc put the ball in the net, but the assistant referee raised the offside flag. In the fifty-eighth minute, Hoang Duc made a penetrating run through Thailand's midfield. Two moments. Only two. In ninety minutes.

That is a worrying signal. A team that wants to impose a match needs to create dozens of such moments, not two. And more importantly: those moments must become automatic behavioural patterns, repeated, trained until they become instinct. In Vietnam today, they remain isolated sparks that depend on individual inspiration.

This is the point I want to stress most in this article. Vietnam's problem is not a shortage of good players. The problem is the absence of an automatic attacking system that can be repeated against deep-defending opponents. When the system has not taken shape, the team must rely on individual moments. And individual moments cannot be predicted, cannot be controlled, cannot serve as the foundation of a long campaign.

Bae Ji-won also mentioned the speed of ball circulation, the ability to sustain pressure, and diversity in attacking options. Those three qualities are tightly linked. If the ball circulates slowly, the opposing defence has time to shift. If pressure is not sustained, the opponent has time to counter. If the attacking options are monotonous, the opposing defence only needs to learn once to neutralise the whole match.

Thailand did exactly that. They learned, and they neutralised.

There is one more detail I want to spend time on. Thailand used Chanathip Songkrasin as a false number nine. Bae observed that this approach did not work as intended. But I think that matters less than its consequence. The mere presence of Chanathip forced Vietnam's centre-backs to push higher to track him, or to worry about his ability to hold up play. That worry created space behind the defensive line.

Thailand did not fully exploit that space. They had an early goal, and they chose to manage the game cautiously. But with a different team, with a faster striker, the story could have been different. This is a warning Vietnam needs to remember.

A comparison with the final on the twenty-sixth of August

There is a way to understand Vietnam's problem more clearly: place two matches against the same opponent side by side.

In the final, Vietnam scored two goals against Thailand. The way those goals came was very different: quick transitions, attacks into the space behind the defensive line, situations where speed and surprise were the main weapons. Back then, Thailand played more openly, they wanted to win, they pushed up. And that very push created space for Vietnam.

This match was the reverse. Thailand did not need to win beautifully. They only needed not to lose. After the tenth-minute goal, they dropped deep and shut the door. They took away the very weapon Vietnam uses most effectively, and forced Vietnam to play in a way it is not good at.

This difference is not about talent. It is about the ability to adapt to the state of the match. A team that wants to win at regional level needs at least two tactical faces: one for matches where it is the hunter, and one for matches where it must break down a wall.

Vietnam currently has the first face at a decent level. The second is still raw.

Squad depth, a problem of an entire system

There is a dimension I want to analyse more deeply, because it is rarely mentioned but decisive.

Bae Ji-won said Vietnam lacks equivalent replacement options. It is a painful but accurate observation.

Look at Thailand's central midfield. It is a trio of players with hundreds of international caps. They understand each other so well they can move without looking. When one pushes up, another drops. When one is pulled wide, another seals the centre. That understanding was built over years and cannot be bought.

Vietnam also has good midfielders. But when Hoang Duc is not at his best, who replaces him? When Quang Hai is injured, who fills the creative gap? The answer in this match was: no one of sufficient calibre.

This is a problem of an entire development system, not of one coach. When you build a national team around a few stars, you are always fragile. When a star gets injured or loses form, the whole building shakes.

Bae suggested that Pham Gia Hung, a player with good aerial ability, should have been sent on late to create chaos in the box. It is a smart suggestion, but it also reveals something worrying: Vietnam lacks all-round replacements and must rely on specialised players for specific situations.

A big team needs both: all-round players who can substitute directly, and specialised players who can change a match in the final ten minutes. Vietnam currently has the second but lacks the first.

This leads me to a thought about the limits of the star model. For years, Vietnamese football has taken pride in producing outstanding players. But a strong football nation is not measured by the number of stars. It is measured by the quality of its eleventh substitute.

In Thailand, when a pillar is injured, they have a replacement. In Vietnam, when a pillar is injured, the whole team must change how it plays. That is the difference between a team and a collection of talented individuals.

The substitution decisions

Bae Ji-won also questioned Kim Sang-sik's substitutions. This is a sensitive topic, but it needs to be analysed frankly.

In a match where the opponent drops deep and shuts up shop, what you need is not another midfielder who can pass safely. What you need is a change in the attacking shape: another striker who can contest aerial balls, a player who can create a spark at the edge of the box, or a structural change to stretch the opposing defence.

The failure to send on Pham Gia Hung, while Williams Minh Hoang was already on the pitch, showed hesitation. It may be a question of trust in substitutes. It may be a question of tactical philosophy. But whatever the cause, the consequence was clear: Vietnam did not create enough pressure in the box in the closing minutes.

This is what I call rigidity in match management. A good coach does not only prepare for how the match begins. He must also prepare for how the match ends, in every possible scenario.

Thailand and the pragmatic winning model

There is a bigger lesson on Thailand's side, and it is worth the whole region reflecting on it.

Anthony Hudson is building a Thai national team different from the traditional image. This team no longer tries to play the beautiful football based on the individual technique of stars like Chanathip. They play more pragmatically, more disciplined, and they know how to accept an ugly match if it delivers three points.

This is causing a debate in Thailand. Part of the fanbase and the experts argue the team is losing its identity. Thai expert Be Bangkapong responded with a very thought-provoking line: looking at the final result is enough.

I do not fully agree with Be Bangkapong, but I understand his logic. In elite football, results are the final measure. Beauty is a value, but it cannot replace winning.

For Vietnam, Thailand's transformation is a warning. If rivals in the region increasingly play pragmatically and disciplined, then relying only on individual moments will become ever more fragile. Southeast Asian football is evolving toward a higher demand for tactical thinking, and teams that do not adapt will be left behind.

Are we overreacting

At this point, I want to turn in another direction. Because there is something public opinion is overlooking, and it matters no less than the tactical analysis.

After the defeat, I read dozens of articles, hundreds of comments. Most said Vietnam revealed many problems, that Kim Sang-sik was wrong, that the national team is in crisis. I understand that feeling. Vietnamese fans love the national team with a fierce love, and when it loses, the pain turns into a need to find someone to blame.

But I want to ask a different question. Are we overreacting?

The whole picture needs to be revisited. Thirty-four days earlier, this team won the title. Four pillars are injured. The opponent scored in the tenth minute and immediately switched to a defensive mode. Those are three compounding disadvantages, and any team in the world would struggle in a similar situation.

I am not saying this defeat is normal. I am saying that drawing quick conclusions from a single match is an analytical mistake. This is exactly the trap I remind myself to avoid: snap judgement before enough sources have been cross-checked.

Bae Ji-won is a respected analyst. But his opinion is that of an outside observer, based on one match. To conclude that the Vietnamese national team has a systemic problem, we need a larger sample. We need to look at a whole cycle, not one night.

What worries me more, in my view, is not tactics. It is the calendar.

Four pillars injured because they had to play continuously over a short period. This is a systemic problem, not an excuse. When Vietnamese football builds its domestic calendar without accounting for the national team's rhythm, when players must grind both at club and national level in narrow time windows, injuries stop being accidents. They become an inevitable consequence.

If we want to talk about the problem of Vietnamese football, this is the biggest one. Not the fact that the team holds the ball a lot without scoring. But the fact that we are burning our best players because we lack a proper load-management system.

And here is another paradox I want to mention. While Vietnamese public opinion criticises its own team, in Thailand coach Anthony Hudson is also being criticised. Not for losing, but for winning without beauty.

Two public opinions, two reactions, one match. The Vietnamese worry because their team cannot attack. The Thais worry because their team attacks without beauty. Both are reacting to the same phenomenon: Southeast Asian football is transforming, and no one is entirely satisfied with its new shape.

This is when I think about something I have learned after many years in this profession. When a football nation is transforming, defeats and victories are both temporary. What endures is the system. And a system only changes when enough people dare to look straight at uncomfortable problems.

What next for Vietnamese football

I want to close with a few forward-looking thoughts, because football does not stop after one defeat.

First, Vietnam needs to build a repeatable attacking system. This does not mean abandoning individual moments, but complementing them with a collective skeleton. Drills on fast ball circulation, off-ball movement, and creating space in tight areas must become a fixed part of the training curriculum.

Second, Vietnam needs a proper load-management programme. Four pillars injured at once is an alarm signal. The medical and fitness staff must have a louder voice in deciding who plays and who rests.

Third, Vietnam needs to invest in squad depth. This requires change at the level of the development system, not just the national team. Academies must produce all-round players, not only specialists for one position.

Fourth, and perhaps most importantly, Vietnam needs to learn to adapt to different match states. A big team does not only know how to attack. It knows how to attack when behind, how to defend when ahead, and how to break down an already-organised defence.

Takeaway

I spent three days rewatching this match, and what I carry away is not disappointment. It is clarity.

The defeat to Thailand is not a full stop. It is a mirror. And this mirror shows us more clearly than any victory.

Southeast Asian football is changing. Teams that know how to defend, how to manage match states, and how to accept the beauty of pragmatism are gradually gaining the upper hand. Vietnam has enough talent to adapt, but talent alone is not enough.

What is needed now is not to find someone to blame. What is needed is to build a repeatable attacking system, a sensible load-management programme, and a generation of substitutes deep enough that no one is irreplaceable.

The match in Bandung is over. But the story of the Vietnamese national team has only just begun a new chapter. And as I wrote thirty-four days ago, sleepless after the championship night: football never lets you rest. It only gives you a moment to breathe, then pushes you into the next match.
