Vietnam without Xuan Son before the decisive clash: Thai fans split into two camps

The pre-match technical press conference in Bandung was unusually heavy. Head coach Kim Sang Sik sat in front of the microphones, eyes fixed on the table, slowly rotating a pen in his hand. Those in the know do not say much; they just rotate the pen. But the question every Thai journalist cared about that evening was not about tactics or specific personnel. All eyes were on one absent name: Nguyen Xuan Son. The injury of the Brazilian-born naturalized striker had just been confirmed as serious, forcing him to leave the tournament right before the direct showdown with Thailand at 19:30 on September 29 at Si Jalak Harupat Stadium. The match is being treated as an early final of Group B. And in the wave of comments flooding Thai social media, one thing came as a surprise: Thai supporters have split into two clearly opposed camps. The first camp, the opportunity camp, rallies around the Kiran Buriram fanpage. They believe Xuan Son's absence is a gift Thailand cannot afford to waste. The second, cautious camp, pulls out a historical memory that makes many pause. They recall the 2026 ASEAN Cup final, where Thailand lost to Vietnam even when Xuan Son could not play. This contradiction between a golden chance and a dangerous trap has created a fascinating psychological picture ahead of the decisive match. In terms of context, Vietnam entered the tournament as defending Southeast Asian champions. They had just played their opening match against the Philippines, where Xuan Son was still on the pitch before suffering an injury in a later training session. This loss not only affects attacking power but also changes how opponents view the group dynamics. In Kim Sang Sik's system, Xuan Son is not simply a goalscoring striker. He is the tactical focal point, the target for long balls, the one who holds up play and creates space for those around him. When you lose a centre-forward with his physique, strength and ability to turn with his back to goal, the red-shirted team is forced to find a new approach. The most mentioned replacements are Ngo Dang Khoa and Williams Minh Hoang, two players of Vietnamese descent naturalized under the homecoming model. They have technique and pace, but none of them has been tested in a high-pressure match like this one against Thailand in an official tournament. This is the biggest data gap I have encountered when trying to measure Vietnam's true strength right now. I have no expected goals numbers, no pressing statistics, no data on shot counts from recent training sessions. All I have are emotional assessments from fans, and for an investigator, that is not enough to reach any firm conclusion. A technical detail also needs to be addressed: the name FIFA ASEAN Cup 2026 widely used by Thai fanpages is institutionally inaccurate. The Southeast Asian championship is not run by FIFA. This detail reminds me that not everything circulating on social media before a match is reliable. It also reflects a larger problem: the level of information accuracy in an age where anyone can become a journalist. Over the past five years, clashes between Vietnam and Thailand have always been intense and decisive in regional tournaments. The 2026 ASEAN Cup final remains the most cited milestone: even without Xuan Son in the starting lineup, Vietnam still had enough composure to lift the trophy in front of tens of thousands of Thai supporters at Rajamangala Stadium. This detail alone makes claims that Thailand will definitely beat a Xuan Son-less Vietnam far less convincing. The most interesting thing from Thai forums is not uniform confidence but strong polarization. The optimistic side keeps calling this match a golden opportunity. Accounts like Gugun, Mammo Oonhak and Ucup Kangkung repeat that Vietnam has just lost its main scorer, a loss compared to losing half the attack. They argue that if Thailand cannot beat a Vietnam without Xuan Son in such an important match, a better chance will never come. The cautious side, by contrast, uses history as a shield. Kotcharat Chinbut, Rungsak Sitthiprasert, Sudswingringo and Pon Phithik all stress that Vietnam won the 2026 ASEAN Cup even though Xuan Son did not play in the final. That memory makes them unwilling to bet on an easy victory. They understand that Vietnam is not a collection of one individual, and losing a star does not mean losing collective identity. Between the two camps, one tactical observation stands out from the account Witayanon Sinlapasiriwat. He argues that Vietnam without Xuan Son will become more unpredictable, because the attack will be more mobile, more expansive, and harder to mark than a target man who simply waits in the box. This assessment has a clear tactical basis. A team used to playing with a focal-point striker is often easy to read. But when shifting to a smaller, more mobile front line, opposing defenders must deal with constant movement, positional exchanges and unexpected through balls. Still, I maintain a methodical scepticism. Based on my experience watching matches, moving from a target man to a fluid attack is never easy in a short tournament. Players need time to adapt, matches to find rhythm, and chemistry that only forms through months of training. Ngo Dang Khoa and Williams Minh Hoang may have talent, but they have never faced pressure in a match of this magnitude. In football, there is a huge gap between talent and the ability to perform under pressure. From a media perspective, I see an interesting paradox. An empty stadium still echoes louder than a closed meeting room. Years in this profession have taught me that public opinion can create pressure but cannot score goals. A penalty missed in the 88th minute is less about crowd emotion and more about technique, preparation and a touch of coldness. Vietnam's experienced players know better than anyone that every social media comment becomes meaningless once the referee blows the whistle. Vietnam still possesses a seasoned core. The names in midfield and defence have played together across many tournaments, survived do-or-die matches and know how to overcome crises. The problem is not whether they have enough quality, but whether they can maintain their connection in a system forced to rebuild its attack at the last minute. In the training sessions I have observed, there is a quiet determination, an internal message being passed around: share the burden, no one is irreplaceable, and victory is the product of the whole team. Thailand, on the other hand, has its own issues. Excessive confidence is sometimes the most dangerous enemy in football. A team entering a big match with the mentality that the opponent has lost a key player and we have the advantage can easily fall into complacency. That state usually comes at the cost of conceded goals. The history of ASEAN Cups has seen many favourites lose because of complacency at the decisive moment. If you look at the bench, Thailand appears more varied in attacking options, but that does not mean they are superior. Recent meetings show that the decisive factor often lies in the ability to handle pressure and composure in the box, not the number of stars on the pitch. In this regard, Vietnam under Kim Sang Sik has shown impressive maturity. I also called a friend who works as an agent in Bangkok. He said many Thai players in the current squad are still haunted by the 2026 defeat. They do not say it out loud, but it lingers in conversations. A team carrying fear will never take full advantage of an opportunity. If you look only at Xuan Son's absence, the story seems clear: Thailand has the advantage. But I believe the blind spot lies elsewhere. One Thai fan account mentioned that Vietnam almost lost to the Philippines in the opening match. If that is true, then Vietnam's problem is not attack but defence. And when the defence has issues, losing the main striker only masks a deeper flaw. Thai fans are so focused on the Xuan Son story that they are missing a vital signal: the real form of the whole red-shirted team in recent weeks. Guangzhou taught me to sit still, listen, and let the truth crawl out on its own. In football, as in life, the most serious problems are often hidden behind the most sensational stories. The loss of a starting centre-forward is a big story, but the holes behind remain, quietly waiting. Thailand can attack the space Xuan Son left, but they can also attack a defence that is said to be fragile. And that is the real question of this match. Moreover, the golden chance narrative ignores a very specific historical fact: Thailand lost the most recent final to Vietnam in a context where Xuan Son was absent. That memory is not accidental. It shows that Vietnam, even without its biggest star, still possesses a collective foundation strong enough to compete for titles. It also shows that Thai players, no matter how confident, will have to face a tactically disciplined opponent and a South Korean coach known for meticulous preparation. The match at 19:30 on September 29 at Si Jalak Harupat Stadium will not only decide the top spot in Group B; it will also reveal how strong Vietnam truly is without its biggest focal point. Thais can believe in the opportunity, Vietnamese can worry about the loss, but football is not decided by social media posts. Russia 2026 had no bench for those who guessed wrong. And in Bandung, when the ball rolls, only those who keep a cool head will advance. Will this be a glorious night for Thailand, or a lesson in arrogance? Will Vietnam prove they depend on no individual, or realise they have lost an irreplaceable piece? No one can answer before the final whistle. And that, perhaps, is the only beauty football offers to those who love predictions.
