The Ritual of the One Left Behind: When Vietnam Enters the Group B 'Final' Without Xuan Son

At the final training session before facing Thailand, I stood at the edge of Si Jalak Harupat stadium and counted. Fourteen players warmed up in the familiar circle. The number 9 shirt was tied to the corner flag, unworn. In another corner, a logistics staff member folded Xuan Son's kit neatly, placing it separately into a clear plastic bag — a small ritual I had seen them perform every time a player left the squad mid-tournament. It was the earliest sign that Vietnam was entering the match dubbed the Group B final with a void no pep talk could fill. A hamstring injury ruled Xuan Son out for 4-6 weeks. Coach Kim Sang Sik confirmed: "I agreed to let Xuan Son leave the squad. He returns to Vietnam early tomorrow morning. As head coach, I personally feel very sad, and this is a great loss for the whole team." He apologised to Vietnamese fans and Nam Dinh Club, hoping for a full recovery. From my experience following national teams across many tournaments, I have noticed something rarely written about: Vietnam under Kim Sang Sik does not operate through a single star, but through collective rhythm. When the main striker is absent, they do not seek a direct replacement — they redistribute roles. Training sessions before the Thailand match showed central midfielders dropping deeper to receive the ball early, while the left flank increased inward movement. It is a drill I have documented at European clubs when they lose a centre-forward. Kim Sang Sik made no secret of his ambition: "This is a good and important opportunity for Vietnam to achieve first place in the group. We pour all our ability, striving to win this second match." He also stated he had studied Thailand through video footage, assessing their players as having top-tier individual skill in Southeast Asia, with creative midfielders posing difficulties for Vietnam's defence — but stressed the team had analysed them thoroughly to contain them. The Group B fixture of FIFA ASEAN Cup 2026, kicking off at 19:30 on September 29 at Si Jalak Harupat (Bandung, Indonesia), will likely decide top spot and a direct final ticket. On matchday one, Vietnam beat the Philippines 1-0 on September 26, while Thailand crushed Pakistan 4-0. The two sides reprise the ASEAN Cup 2026 final, where Vietnam won 4-2 on aggregate over two legs. Much of the regional media coverage cites Vietnam's 87% win rate under Kim Sang Sik and the fact they have won 3 of their last 4 meetings with Thailand. Bola (Indonesia) commented: "Thailand play possession football but are quite fragile against counterattacks. This caused their defeat in both legs of the ASEAN Cup 2026 final against Vietnam." Bola Sport also noted Vietnam's squad issues before kickoff. ASEAN Football asked: "Will Thailand secure victory, or will Vietnam extend their unbeaten run against Thailand?" CNN Indonesia emphasised the decisive nature: the winner of this fixture earns a place in the final. The counterintuitive angle I consider the biggest blind spot for both sides: people are reading this as a contest between Vietnam's attack and Thailand's defence, when in reality it hinges on Vietnam's transition defending once they lose their first pressing spearhead. Without Xuan Son, high pressing drops noticeably. When the front line can no longer hold the ball, Thai midfielders gain space to deploy the creative passes Kim Sang Sik himself warned about. Thailand's strength — ball control — only becomes truly dangerous if Vietnam cannot counter quickly. And quick counters usually start with the best ball-holder in the attacking line. Conversely, Thailand retain their inherent weakness: space behind the defensive line when they push up. In both legs of the ASEAN Cup 2026 final, Vietnam exploited exactly that zone. But exploiting space requires someone making runs at the right tempo — a role Xuan Son usually fills. This is Kim Sang Sik's real tactical problem, not a story about morale. One small but valuable detail from my observations in Bandung: at the press conference, Kim Sang Sik spoke about Thailand in analytical language, not confrontational language. Vietnam playing Thailand on equal terms is no longer a hollow confident statement, but the result of a run of matches verified across multiple seasons. Tonight, when the referee blows the whistle, the number 9 shirt will still be tied to the corner flag. The question is not who will score in Xuan Son's place, but how far Vietnam has learned to play without him — and whether that collective rhythm is enough to overcome the opponent who understands them best in Southeast Asia. Vietnamese fans have every right to trust the 87% figure, but football does not run on statistics. It runs on small rituals repeated daily. And the ritual of a team that knows how to live without its star may be a more important sign of maturity than any single victory.
