Thai Fans Split Over Vietnam Without Xuan Son: Golden Chance or Trap?

Less than 24 hours after news that Nguyen Xuan Son suffered a serious injury and would leave the tournament, Thai football forums exploded. Fanpage Kiran Buriram quickly posted: “This is the time Thailand must seize.” Below it, user Witayanon Sinlapasiriwat pushed back: “Vietnam without Xuan Son can be even more annoying.” In one night, two opposing camps took shape. One saw a historic opportunity; the other saw a dangerous trap. According to the schedule circulated by Thai fan pages, Vietnam will meet Thailand on September 29 at Si Jalak Harupat Stadium in Bandung. The match is treated as a six-pointer: the winner almost certainly takes top spot in Group B and a place in the final. One detail, however, needs attention. Several accounts call the tournament “FIFA ASEAN Cup 2026,” but that name is unverified. The Southeast Asian championship is run by the ASEAN Football Federation (AFF), not by FIFA. The schedule, venue, and even the competition name need official verification before being treated as fact. On personnel, the most discussed point is Xuan Son's injury. Coach Kim Sang Sik loses his main striker and his biggest attacking reference point. Two names, Ngo Dang Khoa and Williams Minh Hoang, are mentioned by Thai fans as replacements. But no official confirmation has come from the Vietnam Football Federation about the final squad or the exact severity of Xuan Son's injury. This is a major blind spot: current analysis rests on rumors and emotional comments. Thai fans are split into two opposite camps. The first, the “opportunity” camp, believes Xuan Son's absence opens the title door wider than ever. User Gugun wrote: “Without Xuan Son, Vietnam loses at least 70% of the pressure on goal. If we do not win this match, forget about the title.” Mammo Oonhak said bluntly: “This is a wrapped gift. Thailand just needs to go to Bandung, play well, and take three points.” Ucup Kangkung added: “Xuan Son is a player who can turn, shield the ball, absorb contact, and finish with both feet. He is the only striker in Southeast Asia who forces defenders to double-mark him. With him gone, Thailand's back line only needs to play as it did in the group stage.” The second, cautious camp argues the opposite. Kotcharat Chinbut cited history: “In the 2026 ASEAN Cup final, Xuan Son was injured and Thailand still lost to Vietnam. Are you sure they will collapse just because they lack one striker?” Rungsak Sitthiprasert added a worrying signal: “I watched Vietnam against the Philippines. They almost lost. If a team almost loses to the Philippines, the problem is not the attack but the defense.” Sudswingringo agreed: “Do not look only at Xuan Son. Vietnam still has Ngo Dang Khoa and Williams Minh Hoang. These naturalized players are not nobodies. They may not be as good as Xuan Son, but Thailand should not treat them as unknown names.” Pon Phithik warned: “When a team faces a big chance, it tends to become overconfident. Overconfidence is the beginning of defeat.” From a tactical perspective, both camps have a point, but the answer lies in how Kim Sang Sik handles the personnel problem. Xuan Son is a target man. He does not only score; he is also the destination for long passes and the wall who enables midfielders to push up. When such a reference point is lost, a team must shift from concentrated attacking to distributed attacking. That may make Vietnam's attack harder to read. Witayanon saw this correctly when he said Vietnam becomes “more flexible.” Instead of one fixed central striker, players like Ngo Dang Khoa or Williams Minh Hoang can constantly swap positions, drop deep, and create spaces behind the midfield line. In modern football, the number 10 does not die; it just learns to run faster. Vietnam may use a “false number 10” — a player who drops deep and is not marked by a fixed defender — to stretch Thailand's defense. But the cost is also huge. Without a target man, Vietnam loses aerial pressure and direct physical penetration. Thailand's defense no longer has one fixed “target” to mark, but it can push higher because Vietnam will rely less on crosses and headers. If Kim Sang Sik chooses counter-attacking football, he needs wingers with pace and composure in tight spaces. This is the moment for the naturalized players to prove their value, and also the moment the tactical system faces its harshest test. There is another key blind spot. People see Xuan Son absent; I see a crack in the defensive line. If the claim that Vietnam “almost lost to the Philippines” is accurate, Vietnam already had problems before the striker got injured. Losing a striker reduces attacking power, but a distracted defense will cost the team dearly against Thailand. Public discussion is focused on the number 9 position, but perhaps “Brazil do not lose in the 90th minute; they lose when they choose the wrong question.” If Vietnam only patches the attack without checking its ability to cope with counter-attacks, the risk of failure is very real. At a deeper level, this story reflects the naturalization revolution happening across Southeast Asia. Vietnam is not the only team using naturalized players; Thailand, Indonesia, and the Philippines are also following a similar model. But relying too heavily on these players makes a team vulnerable when a key pillar is injured. For Vietnam, adding Ngo Dang Khoa and Williams Minh Hoang is a depth investment, but that depth has not been tested in a big match. A naturalized player may suit his club environment, but the pressure of the national jersey in front of a huge crowd is a completely different story. From my experience watching matches, naturalized players usually need at least one tournament to adapt to the dressing-room culture. If Kim Sang Sik rushes them into the Thailand match, the risk of mistimed integration is real. Pressure is now on coach Kim Sang Sik. He will be judged by how quickly he rebuilds the attack. If Vietnam play well, he is a strategist; if they fail, the “dependence on Xuan Son” narrative will haunt them for years. But football is not mathematics. A team can change its identity with small positional tweaks. Kim Sang Sik could put Ngo Dang Khoa at the highest point, Williams Minh Hoang behind him as the playmaker, and widen the two wings. In that setup, Vietnam's attack is no longer a single spearhead but a network of constant movement. This is exactly what the cautious Thai fans fear. Thailand, for their part, have reasons to believe in themselves. This generation presses at high tempo, counter-attacks quickly, and controls possession well. If they push high from the start, they can exploit Vietnam's defensive uncertainty. But if they get dragged into a slow rhythm, they will become the ones chasing the ball. The match could be decided in the first ten minutes. The team that controls the tempo first will have the big advantage. Ironically, Xuan Son's absence may make Vietnam more proactive in choosing how to approach the game. They no longer need to obsess over serving one central striker. Recent history does not favor the “opportunity” camp. In the 2026 ASEAN Cup final, Vietnam beat Thailand even though Xuan Son was not fully fit. That shows this squad has its own resilience. But football is only judged in the present. The match in Bandung brings away-day pressure, weather conditions, a short preparation window, and a Thailand side with hungry young players. Vietnam may use squad depth, but depth only matters when the machine runs smoothly. Football does not accept calculations based on reputation. A strong team on paper can collapse if it lacks cohesion for ninety minutes. The interesting part is that Thai fans are creating a parallel psychological battle. One side sees an unmissable chance; the other sees a trap of arrogance. This split reflects the true nature of the match: no one knows the real balance of power. If Thailand enter with the mindset that “not winning is failure,” they will put enormous pressure on themselves. Conversely, if Vietnam choose negative defending because Xuan Son is missing, they will lose their identity. Vietnamese supporters want to see an active team, one that dares to press, attacks down the wings, and controls the rhythm. Statistically, no xG, xGA, or PPDA numbers have been published for this match. The circulating information is mostly fan sentiment, not official data. That means claims like “Vietnam are stronger” or “Thailand will win” lack quantitative support. Southeast Asian football depends heavily on mental state, and the mood of fans cannot replace the form of players on the pitch. The September 29 match will answer everything. I do not buy the “golden chance” story or the “collapse” scenario. I believe in a more precise question: without Xuan Son, which tactical approach will Vietnam use to score, and will Thailand's defense dare to push high and exploit the space behind Vietnam's defenders? Small details — aerial duels, wing play, pressing intensity — will decide everything. Vietnam lost a striker, but not necessarily a way of playing. As long as they ask themselves the right question before kickoff, everything remains within reach.
