Cracks After Sunset: When Vietnam Lost Its Spearhead Named Xuan Son

Minute 63. The ball left Hoang Duc's boot, flew over the crossbar of Thailand's goal, touched the empty space behind, and fell onto the wet grass. I sat in front of the screen in Singapore, the room lights off, only blue light casting onto the white wall. No cheers. No applause. Only the sound of studs scraping the pitch and the sighs of a stadium slowly understanding what no one wanted to put into words.

That was the moment I realized: Vietnam had not simply lost a match. A system was dismantling itself piece by piece, and people only saw the tip of the iceberg — the absence of Nguyen Xuan Son.

I have followed Southeast Asian football from the Jalan Besar stands since 2026, when a 90+2 volley from Gabriel Quak taught me that decisive moments never come from where people expect. And on the night Vietnam lost 0-2 to Thailand, the decisive moment came from an empty place — the striker position Xuan Son left behind.

Context: A title contender with an incomplete squad

The match took place in the group stage of a Southeast Asian regional tournament. Vietnam entered as a title contender, a team that had finished as regional runner-up and was rated on par with Thailand. But from the registration list, unusual signs appeared.

Coach Kim Sang Sik did not have a full squad. The team was missing many key players due to injuries and fitness issues. Xuan Son — the naturalized striker, the team's number one spearhead — suffered an injury from the first match and could not continue. Hoang Duc had just returned from injury, not yet at peak fitness. Many other players were assessed as not being in good physical condition.

This is the context any analyst must put on the table before talking about tactics. A team entering a major tournament with an incomplete squad, uncertain fitness, and a main striker out of action — that is the formula for systemic problems, not for a single defeat.

Thailand entered this match with the opposite advantage. They had a deeper midfield, allowing the coach to substitute without losing quality. They had Chanathip Songkrasin — a player capable of playing as a false nine, stretching the opponent's defense and creating space for teammates. They had Sarach Yooyen — capable of unleashing deadly long-range shots.

The difference in squad depth was most evident in midfield. Thailand could bring on midfielders of quality equivalent to the starters. Vietnam — with a thin midfield — was forced to use makeshift solutions, even pulling a full-back into central midfield.

Tactical analysis: When Vietnam's midfield was suffocated

The match began with the scenario many predicted: Vietnam held more possession. But controlling the ball does not mean controlling the match. In the first half, Vietnam dominated possession but created almost no truly dangerous chances. Attacks mostly ended with long-range shots from outside the box — the typical signature of a team stuck in breaking down the opponent's defense.

The opening goal came from a long-range shot by Sarach Yooyen. That was the moment Thailand demonstrated the difference in individual quality at decisive moments. But more importantly, that goal completely changed the match.

After taking the lead, Thailand deliberately dropped deep, organized a low block, and waited for counter-attacking opportunities. This was a well-designed tactic, not a passive reaction. They understood that Vietnam — missing its main striker — would struggle to break down a crowded defense. And they were right.

The higher Vietnam pushed, the larger the space behind. Thailand waited for long balls over the top and quick counter-attacks. They did not need to control the ball to control the match. They only needed to control space and timing.

This is a classic tactical lesson: a team deliberately cedes the initiative to protect a lead and wait for the opponent's mistakes. Thailand executed this perfectly. They did not need to win the possession statistics. They only needed to win the goal statistics.

Xuan Son's absence: Losing a player or losing an entire system?

This is the central question of any analysis of this match. And the answer — according to expert Doan Minh Xuong — is that Vietnam lost an entire system.

Xuan Son is not merely a goalscorer. He is a link with a special function in Vietnam's attacking system. The ability to shield the ball, to operate independently, and to physically occupy the opponent's center-backs — these are qualities no Vietnamese player can replace.

Without Xuan Son, Vietnam lost the ability to hold the ball up front. The ball was not held long enough for the midfield to push up in support. Midfielders had no safe outlet to pass to. And Thailand's defense — already well-organized — became even more solid because it did not have to face a striker capable of physical duels.

This is what I call the "domino effect of a striker." Losing a player in the spearhead position does not only affect scoring ability. It affects the entire attacking chain, from ball retention to circulation to creating space for other players.

In modern football, the role of a striker has changed greatly. No longer just a player waiting in the box to score. A modern striker must participate in the collective play, create space for teammates, and pressure the opponent's defense. Xuan Son — with his superior physicality — meets these requirements to a degree no domestic player can.

The dependence on Xuan Son also raises a question about Vietnam's football development strategy. Having to naturalize a striker to solve the attacking problem shows a shortfall in developing domestic players in this position. This is a systemic issue that needs to be addressed at the academy and youth development level.

The formation change: When a full-back has to play central midfield

In the second half, Coach Kim Sang Sik made a notable tactical change. He switched from a 3-4-3 to a 3-5-2, pulling Cao Quang Vinh — a full-back — into central midfield. This decision says a lot about the state of Vietnam's squad.

When a full-back has to play central midfield, it means the team is severely short of personnel in the middle. This is not a bold tactical choice. It is a makeshift solution, a response to a shortage of resources.

The change had some effect. Vietnam played with more cohesion in the second half, especially after Hai Long and Hoang Duc came on. But cohesion does not mean sharpness. Vietnam still could not create truly dangerous chances. They still relied on long-range shots — a weapon Thailand easily dealt with.

This change also reveals a tactical limitation of Coach Kim Sang Sik. In modern football, a good coach needs the ability to adapt to various situations. But when resources are limited — both in personnel and fitness — the ability to adapt is also limited. This is a difficult problem with no simple solution.

Chanathip and the false nine role: Thailand's tactical weapon

On the other side, Thailand had a tactical weapon Vietnam could not handle: Chanathip Songkrasin in the false nine role. Chanathip does not play like a classic striker. He drops deep into midfield, creating chaos in Vietnam's defense.

When Chanathip drops deep, Vietnam's center-backs must decide: follow him or not? If they follow, the defense is stretched and space opens behind. If they do not, Chanathip has time and space to organize attacks. This is a dilemma that Vietnam's thin midfield could not solve.

Chanathip's flexibility allows Thailand to easily switch between attacking and defensive states. When they need to control the ball, they feed it to Chanathip. When they need to counter, they use his passing ability to open up quick breaks. This is the tactical variety that Vietnam — with a single-threaded attacking system — could not match.

Chanathip's false nine role also poses a personnel challenge for Vietnam. To deal with such a mobile player, the team needs midfielders capable of tracking and reading situations well. But with a thin midfield and many players not at peak fitness, Vietnam could not maintain the necessary concentration throughout the match.

Sterile domination and the problem of breaking down a low block

One of Vietnam's biggest problems in this match was the ability to break down a low block. Thailand deliberately dropped deep, organized into two or three defensive lines, and waited for Vietnam to make mistakes.

Against such a block, Vietnam needed small combinations, through-balls, and intelligent off-the-ball movement to create space. But they could not do it. Vietnam's attacks mostly came from the flanks, with crosses into the box and no one to meet them. Or long-range shots from outside the box — low-probability chances.

This is the signature of a team stuck for attacking ideas. Without a striker capable of duels and ball retention, attacks become predictable and easy to defend. Thailand only needed to protect the central zone and wait for high balls from the flanks.

In modern football, the ability to break down a low block is one of the most important skills of a big team. Top teams have diverse attacking options: central combinations, wing attacks, long shots, aerial balls, and set pieces. Vietnam — with a single-threaded attacking system — lacks this diversity.

Fitness and preparation: The overlooked warning signs

One of the least-mentioned but most impactful factors in the match was fitness. Many Vietnamese players were assessed as not being in good physical condition. Hoang Duc had just returned from injury. Xuan Son was injured from the first match. These are signs that preparation and load management had problems.

In modern football, fitness is not just the ability to run fast and long. It is the ability to maintain high intensity throughout a match, to perform continuous pressing, and to recover quickly between matches. When a team enters a tournament with many players not at peak condition, that is a sign of a systemic issue.

Having to use a full-back in central midfield also partly reflects the fitness problem. When central midfielders do not have enough stamina to play the full match, the coach must find solutions from other positions. This is a makeshift solution, not a carefully prepared tactic.

Fitness also affects the team's pressing ability. To execute an effective pressing system, players need peak fitness and good coordination. When fitness is not assured, the team is forced to drop deep and wait — which Vietnam did in the second half.

The inverted game state: When Vietnam lost its best weapon

This is perhaps the most important tactical point. According to expert Doan Minh Xuong, Vietnam is strongest when playing defensive counter-attack. That is the team's tactical identity — the ability to defend tightly and counter quickly.

But in this match, Vietnam was forced to push high to find an equalizer. They were forced to play football that is not their forte. Losing the defensive counter-attacking advantage, Vietnam became more vulnerable to Thailand's counter-attacks.

This is a tactical paradox: the team strongest in defensive counter-attack was forced to attack. And when attacking, they exposed their limitations in breaking down defenses and scoring. Thailand — with the lead — only needed to wait and exploit the spaces Vietnam left behind.

This paradox also raises a question about Coach Kim Sang Sik's tactics. Can he build an effective attacking plan when the team is forced to attack? Can he find a way to maintain balance between attack and defense? These are questions that need time to answer.

The VAR-disallowed goal: A fateful moment

In the match, there was a moment when Vietnam put the ball into Thailand's net, but the goal was disallowed by VAR for offside. This was one of those moments that could have changed the match. If the goal had stood, the situation might have been different.

But this is also an example of the harshness of modern football. VAR can change a match result in seconds. And in this case, it did not favor Vietnam. However, one must look objectively: a disallowed goal cannot hide the team's deeper tactical problems.

The disallowed goal also shows something about Vietnam's chance creation. The team can create chances — but not enough to make a difference. In a match where the opponent defends tightly, missing one chance can be the difference between winning and losing.

Systemic problems: What is really happening?

Looking at the big picture, many systemic problems exist in Vietnamese football. The team entered the tournament with an incomplete squad. Many players were not at peak fitness. The midfield was so thin that a full-back had to cover.

These problems cannot be explained by the absence of one player alone. They reflect deeper issues in preparation, fitness management, and squad building.

This is the time to review how Vietnamese football operates at the national team level. How to ensure players get adequate rest and recovery between matches? How to build a squad with real depth? How to develop domestic strikers who can step in when needed?

These questions are not new. They have been raised many times before but never thoroughly resolved. And until they are, Vietnamese football will continue to face similar problems.

The blind spot of collective memory: When narrative hides truth

After the match, the story told by the media was quite simple: Vietnam lost because Xuan Son was absent. This is an easy story to understand, easy to sympathize with, and easy to accept. It explains the defeat with a single cause and places responsibility on a factor beyond the coach's control.

But this story hides other problems. It does not explain why Vietnam's midfield was so thin. It does not explain why many players were not at peak fitness. It does not explain why the team had no Plan B when it lost its main striker.

This is the blind spot of collective memory. When a story is repeated enough, it becomes accepted truth. And deeper problems are pushed to the margins.

Notably, this story also benefits Coach Kim Sang Sik. If the defeat is explained by Xuan Son's absence, then the coach is not responsible for preparation, fitness, and squad depth issues. This is a smart way of managing public opinion, but it does not help solve the real problems.

The responsibility of the coach and staff

Coach Kim Sang Sik is under great pressure after this defeat. He is the one making decisions on tactics, personnel, and in-game changes. His decisions — switching from 3-4-3 to 3-5-2, using a full-back in midfield — are the decisions of a coach trying to cope with limited resources.

But the reverse question must also be asked: did the coach have enough time and resources to prepare the team better? Are the fitness and injury issues beyond the coaching staff's control? Or are they the result of an ineffective management process?

These are hard questions, and perhaps more time and data are needed for accurate conclusions. But one thing is clear: responsibility cannot rest solely on an absent player.

In modern football, the coach's role is increasingly complex. A coach is not just a tactician but also a personnel manager, fitness manager, and psychologist. When a team has problems in many aspects, the coach's responsibility becomes heavier.

Lessons from Thailand: Tactical diversity and squad depth

Looking at Thailand, one can see a model worth learning from. They have squad depth sufficient to substitute without losing quality. They have multiple attacking options — from central combinations to quick counter-attacks from the flanks. They have players capable of creating breakthroughs like Chanathip and Sarach.

Thailand's tactical flexibility allows them to adapt to various match states. When they need to attack, they have players capable of creating chances. When they need to defend, they have players capable of organizing and protecting the goal. This is the balance Vietnam — with a single-threaded attacking system — lacks.

Thailand also shows the importance of developing domestic players. Chanathip is a product of Thai football, not a naturalized player. This shows Thai football has an effective youth development system capable of producing high-quality players.

The road ahead: What needs to change

Looking to the future, Vietnamese football needs to solve many problems at once. Tactically, the team needs to develop an attacking plan that does not depend on a single player. In personnel, it needs to develop and give opportunities to domestic strikers. In fitness, it needs to improve load management and recovery.

But most importantly, the way we view defeat needs to change. Instead of seeking a single cause to explain everything, defeat should be seen as an opportunity to learn and improve. Instead of placing responsibility on an individual, we should look at the system and structural issues.

Vietnamese football has made significant progress in recent years. The national team has achieved impressive results at the regional level. But to sustain and build on those achievements, a more comprehensive approach is needed — not just focusing on immediate results, but on building a solid foundation for the future.

Conclusion: When the ball slows down

The ball slows down when 90+2 knocks. But in this match, the ball slowed long before — from the moment Xuan Son left the pitch injured, from the moment Vietnam's midfield exposed its thinness, from the moment the team realized it had no Plan B.

Before it was a fact, it was a volley. And before it was a defeat, it was an opportunity to prepare better. The question is not whether Vietnam can beat Thailand with Xuan Son. The question is whether Vietnam can build a team that does not depend on any individual.

The stadium is empty, but the city still breathes with every pass. And in that breath, there is a belief that Vietnamese football will find its path — not by seeking a new hero, but by building a system strong enough not to need one.

Every assist is a poem that has not yet been titled. And the poem of Vietnamese football is still being written, line by line, from the cracks and the empty spaces.
