Vietnam national team faces major challenge at FIFA ASEAN Cup 2026: Only two training sessions before opening match

The Vietnam national team enters the FIFA ASEAN Cup 2026 as defending champions, but their title defense immediately faces a major logistical and tactical obstacle. According to coaching staff sources, the team will have only two official training sessions before the opening match against the Philippines on September 26. This raises serious questions about head coach Kim Sang Sik's ability to implement his tactical system with such limited preparation time. Vietnam is placed in Group B alongside Thailand, the Philippines, and Pakistan. The stated goal is to top the group and reach the final. However, the team's assembly schedule is tight: players gather on September 21, depart for Indonesia on September 23, and have only two training days before the first match. The match against Thailand follows just three days later, on September 29, creating a physically and mentally demanding sequence. Attention is focused on the rematch with Thailand, seen as the main rival for the title. This match carries psychological weight: winning reinforces Vietnam's champion status, while losing invites narratives of a fortunate previous victory. However, the compressed schedule makes peak performance in both matches nearly impossible with the available training time. The key tactical decision is squad continuity. The coaching staff has retained most of the title-winning core, betting on existing tactical memory within the group to compensate for the short camp. However, the midfield is a clear weak point. Midfielder Nguyen Van Vi is ruled out through injury, while the return of Nguyen Hoang Duc remains uncertain. If Hoang Duc is unavailable, Vietnam loses a crucial link between defense and attack, forcing a more wide-oriented or transition-based approach. Physical conditioning, not tactics, is the binding constraint. A high-pressing system or complex formation cannot be assimilated in two sessions. Coach Kim Sang Sik will likely adopt a safer, lower-risk approach, controlling tempo rather than pushing for high intensity. This is a clear disadvantage compared to opponents with longer preparation. A structural factor is the V-League calendar. The squad is drawn mainly from LPBank V-League 2026/27 clubs, and the squad announcement comes only after the second round of the domestic league. This means clubs prioritize their commercial schedules over national team preparation, leading to the late release of players and the compressed camp. Is the Vietnam-Thailand match truly decisive? Media and fans consider it an early final, but both teams are in Group B, and multiple slots may be available for advancement (group winners and runners-up). Thailand also faces its own fitness and personnel challenges. A draw or narrow defeat does not necessarily eliminate Vietnam. The psychological pressure may be overstated; in tactical reality, preserving energy for subsequent matches (against Pakistan on October 2) is key for a long tournament run. Additionally, the competition named 'FIFA ASEAN Cup 2026' features a tiered structure (Division 1) with a third-place playoff. Pakistan's presence—a South Asian team—adds diversity but complicates relative strength assessments. With only two training sessions, Vietnam will not show an optimal tactical face against the Philippines. Instead, they will play pragmatically, prioritizing not losing before thinking about winning. The Thailand match will be the real test of Kim Sang Sik's nerve and adaptability. Whether he risks a new system or sticks to the winning formula will be answered within a week. Regardless of results, the lesson is clear: adequate preparation time is a prerequisite for regional competition. Without resolving the calendar conflict between national team and clubs, underwhelming performances will continue.
