What Thai Fans Think About Vietnam Without Xuan Son

Kiran Buriram, a Thai football fan page focusing on Southeast Asian football, did not hide its excitement when confirming that Nguyen Xuan Son had to leave the tournament due to injury. The status update, shared hundreds of times that evening, read: “Vietnam just lost their most dangerous weapon. Thailand's window has opened.” But in the comments below, a major argument broke out. It was not Vietnamese fans responding, but Thai fans themselves splitting into two clear camps. One side called it a golden opportunity, while the other pointed to the 2026 ASEAN Cup final and warned that Vietnam had won even when Xuan Son could not play the full match. The event in question is the serious injury of the naturalized Brazilian-born striker, considered Vietnam's main attacking anchor under coach Kim Sang Sik. Before the tournament, almost every tactical analysis in Southeast Asia focused on how to stop Xuan Son. He was not just a scorer; he was the final destination of every attacking move, the player who held up the ball, created space and served as a reference point. His absence forces the coaching staff to rebuild the entire attacking approach. A Thai fan account claimed Vietnam “almost lost” to the Philippines in their most recent match, only getting a favorable result thanks to a late moment of luck. This information has not been verified with official match data, but it was enough to convince one group of Thai fans that now is the time to strike. The context became even more tense with Vietnam facing Thailand on September 29 at Si Jalak Harupat Stadium in Bandung, a match widely seen as deciding first place in Group B and a ticket to the final. Thai comments quickly split into two opposing camps. The first camp, the “golden opportunity” group, believes Xuan Son's absence removes Vietnam's greatest strength. Gugun wrote: “Without Xuan Son, Vietnam will have no one to meet those crosses. This is the time for Thailand to attack straight through the middle.” Mammo Oonhak said: “The game against the Philippines showed Vietnam's defense is fragile. If Thailand plays to its potential, we will win.” Ucup Kangkung even suggested that Thailand's coach should use the strongest lineup from the start to “finish the opponent before they regain their rhythm.” Kotcharat Chinbut recalled the final defeat: “We lost to Vietnam because they had a center-forward who could score. Now that striker is not on the pitch.” Rungsak Sitthiprasert asked: “If not now, then when? Thailand should exploit the absence of the biggest star on the other side.” The second camp argues the opposite. Witayanon Sinlapasiriwat offered a tactical insight: “Vietnam without Xuan Son will not become weaker, but more unpredictable. They no longer have to pass to a fixed point; they can move more and switch positions more.” This counter-intuitive view has real merit. A team used to playing with a target man often becomes too predictable. Without him, they are forced to become more flexible. Thailand's defense will no longer have one fixed man to mark, but instead face a front line that constantly rotates. Pon Phithik reminded everyone of the 2026 ASEAN Cup final: “We lost the final even though Xuan Son was not fully fit. Vietnam still lifted the trophy. So why do we think they will collapse just because they lack one player?” This comment points to the biggest blind spot of the “golden opportunity” camp. Recent head-to-head history does not support the idea of an easy Thai victory. The split among Thai fans is itself a sign of uncertainty, not absolute confidence. The key tactical point is that losing a target man can be offset by a more distributed attacking system. Vietnam still has other naturalized players such as Ngo Dang Khoa and Williams Minh Hoang. They are not copies of Xuan Son, but their presence shows that Vietnam's squad-building process is not dependent on one individual. The question is whether they can prove themselves in a high-stakes match against Thailand. The biggest issue Thai fans are ignoring might not be Vietnam's attack, but Vietnam's defense. If the claim about “almost losing to the Philippines” is accurate, then Vietnam's defensive problems existed long before Xuan Son was injured. The debate about the absent striker may be distracting everyone from a deeper issue. If Vietnam pushes too many players forward to compensate, the defense will leave even more space, and Thailand's fast wingers are exactly the kind of players who can punish that. Psychologically, losing a star can sometimes free a team. Without Xuan Son, the pressure of “winning through one individual” disappears. Vietnam no longer has any reason to play predictable passes into the striker. They can play more direct, faster football. A team without a fixed number nine but with speed and mobility can be harder to handle than a team relying on a static center-forward. Thai fans in the “golden opportunity” camp may be creating pressure on their own team. When a team is placed in a “must win” position, impatience can take over. Players may push too high, leave space behind, and allow Vietnam to counter-attack. The match will be decided not just by individual quality, but by emotional control. The original article we analyzed did not provide tactical data such as xG, pressing numbers, or possession. It was based entirely on fan reactions. That makes it more of a sentiment snapshot than a factual report. Based on my experience following Southeast Asian football, matches between Vietnam and Thailand are usually decided by which team makes fewer mistakes at key moments. Xuan Son may be the scorer, but before the goal there must be a system delivering the ball to the right place. If the system breaks down, no striker can save the result. Vietnam and Thailand remain the two dominant forces in Southeast Asian football. Recent history gives Vietnam a psychological edge as the reigning regional champion. In the 2026 ASEAN Cup final, Vietnam still beat Thailand even with Xuan Son not fully fit. That detail is the strongest weapon of the cautious Thai fans. They understand that football does not work like a simple addition and subtraction problem. The passionate arguments among Thai fans prove they are not sure about their own team's true strength. Real confidence is quiet. If they truly believed in a “golden opportunity,” they would not need to convince each other so intensely. Vietnam, by contrast, is in the position of “wounded but not finished.” Lowered expectations may actually help the players play with less pressure. The pitch never lies. Only the way we read the game can be wrong. The match on September 29 will not only decide first place in Group B; it will also be a test of character for both footballing nations. If Thailand wins, the “golden opportunity” talk will be praised. If Vietnam wins, it will be the strongest answer to those who believe Kim Sang Sik's team depends only on one player. The open question is not whether Vietnam is strong or weak without Xuan Son, but whether Southeast Asian football is ready to see Vietnam as a collective team rather than a team obsessed with one name. When the noise from social media fades, only the actions on the pitch can answer.
