Losing Xuan Son, Vietnam National Team Enters 'Final' of Group B Against Thailand

During the afternoon training session on September 28 in Bandung, while Indonesian television cameras were still recording from the corner of the pitch, Coach Kim Sang Sik called the captain aside for a private conversation lasting nearly ten minutes. No whistle sounded, but that moment marked a shift in how Vietnam prepared for the match against Thailand. Xuan Son had left the national team in the early morning of September 28 after being diagnosed with a hamstring injury, with an expected recovery period of 4 to 6 weeks. A match described as the final of Group B, and the main striker is no longer there. Coach Kim Sang Sik did not avoid responsibility. Speaking to the media, he said: "I agreed to let Xuan Son leave the national team. He will return to Vietnam early tomorrow morning. As head coach, I personally feel heartbroken, and this is a big loss for the whole team. I want to send my apologies to Vietnam's football fans and to Nam Dinh Club regarding this incident." A coach willing to apologize to the media at a sensitive moment is not common in regional football, and the way he handled this crisis reflects a notable match-management philosophy. Before this crucial match, losing the main striker forces Vietnam to restructure its attack. In the last three matches with Xuan Son on the pitch, Vietnam averaged 14.3 shots per game, with 41% coming from attempts inside the box. Without him in the lineup, this number drops to 9.2 shots per game, and the rate of shots inside the box falls to 28%. This is not just a personnel issue but an attacking structural issue: without a pivot to hold the ball up front, midfielders are forced to play longer balls or circulate more slowly, reducing the ability to exploit space behind the opposing defense. Notably, Coach Kim Sang Sik still maintains necessary confidence. He assessed: "This is a good and important opportunity for Vietnam to achieve first place in the group. We will devote all our energy and strive to win this second match." Regarding the opponent, he said: "Through video clips, I studied the opponent. In fact, at ASEAN Cup 2026, Vietnam and Thailand met in the final, so we know their strengths and weaknesses to exploit, and accordingly have a plan to respond." Assessing Thailand more specifically, the Korean coach commented: "Their players all have individual skills and technical ability among the best in Southeast Asia, their midfielders play creatively, so Vietnam's defense will face difficulties. However, as I said, the whole team has the best preparation, analyzed the opponent carefully, so we can stop them. The whole team is ready for tomorrow's match." The absence of Xuan Son raises a larger tactical question: will Vietnam play purely counter-attacking defense, or try to control the ball from the start? Recent head-to-head history shows Thailand is a good ball-control team but fragile when countered. In the two legs of the ASEAN Cup 2026 final, Vietnam exploited the space behind Thailand's defense to win with an aggregate score of 4-2. In the last four meetings with Thailand, the "Golden Star Warriors" won three. And according to statistics, Vietnam achieved a win rate of up to 87% under Coach Kim Sang Sik. Indonesian media assess this will be an intense and dramatic match. Bola newspaper commented: "Both Vietnam and Thailand won their first matches. Thailand had a convincing performance beating Pakistan 4-0, while Vietnam defeated the Philippines 1-0. This match also recreates the recent ASEAN Cup 2026 final." The newspaper predicted: "Thailand plays possession football but is quite fragile in counter-attacking defense. This caused them to fail in both legs of the ASEAN Cup 2026 final against Vietnam. Meanwhile, Coach Kim Sang Sik's squad will try to exploit the space behind Thailand's defense." ASEAN Football, a page specializing in Southeast Asian football, also spoke up: "The biggest confrontation in regional football is about to be recreated. Will Thailand win, or will Vietnam extend their unbeaten streak against Thailand? This is a match for the pride of both sides." CNN Indonesia shared information: "There are two matches today at FIFA ASEAN Cup 2026. Both belong to Group B Division 1. Notably, the clash between Vietnam and Thailand at 19:30. Both teams won all three points on opening day. Both want to qualify for the final, and the winner will get the ticket to the aforementioned final." From a referee's perspective, this match will depend heavily on how fast counter-attacks are handled on both flanks. When Vietnam no longer has a striker strong in aerial duels and ball retention, counter-attacking situations will shift to overlapping wing play and one-touch combinations in central areas. This requires the referee to control fierce tackles in the midfield zone, where both teams will contest every meter of the ball. A timely whistle can extinguish the risk of widespread conflict; a wrong whistle can turn the match into a card battle. The match between Vietnam and Thailand will take place at 19:30 tonight (September 29), at Si Jalak Harupat Stadium (Bandung, Indonesia). This is the pairing that the football world and regional media are very interested in, and is the match most likely to directly decide the top of Group B along with the ticket to the final. There is a detail rarely mentioned by the media: the last time Vietnam had to play a decisive match without its main striker, they won thanks to a goal by a fullback from a set-piece situation. That is something both teams should keep in mind, because when gaps open in the attack, football is often decided by plays no one expects. Data does not blow the whistle, but it illuminates the angles the naked eye misses. In a match where emotions can overwhelm reason, the one who keeps a cool head is usually the one who lifts the trophy.
