Thailand may continue to 'hide A-team' at FIFA ASEAN Cup 2026

Southeast Asian football is entering a new era with the FIFA ASEAN Cup 2026, the first tournament directly organized by FIFA instead of the AFF. In this context, the story of Thailand possibly continuing to 'hide their cards' – not calling up their strongest squad – is becoming a focal point, especially ahead of the crucial clash with Vietnam on September 29.

Back in January 2026, Thailand reached the ASEAN Cup final with a squad widely considered a 'B-team' – missing many key stars. They lost to Vietnam 2-4 on aggregate over two legs, but according to experts, the Thai team caused a lot of difficulties for Vietnam's strongest lineup. Will Thailand repeat this scenario at the FIFA ASEAN Cup 2026?

The power of Thai clubs – the biggest obstacle

One of the core factors preventing Thailand from fielding their strongest squad is the overwhelming power of domestic clubs. According to analysis, big Thai clubs 'have far more power than the national team'. They often give 'hundreds of reasons' to keep players at their clubs instead of releasing them for national duty. This creates a paradox: theoretically, clubs are obliged to release players during FIFA Days, but in practice, they find ways to circumvent the rules.

Why do Thai clubs have such power? The main reason lies in the financial structure. Thai clubs pay high salaries, comparable to many regional leagues, and they do not want to lose players during critical periods of the season. The FIFA ASEAN Cup 2026 takes place from September 24 to October 5, which falls in the peak period of the Thai League. Clubs competing for the title or avoiding relegation will be reluctant to lose their key players.

FAT's promise – is it strong enough?

Facing public pressure, the Football Association of Thailand (FAT) has declared it will 'do its utmost' to have the strongest squad for the FIFA ASEAN Cup 2026. However, expert analysis suggests this promise may be merely 'performative'. Without real enforcement mechanisms, FAT will struggle to change the power dynamics deeply embedded in Thai football.

In fact, FAT's public commitment is also a way to put pressure on clubs. If the national team fails, public opinion will criticize the clubs, and FAT can use this promise to shift blame. But in the short term, the likelihood of Thailand having their strongest squad remains uncertain.

Vietnam – advantage from stability

In contrast to Thailand, Vietnam does not face similar problems. At the ASEAN Cup 2026, Vietnam fielded their strongest squad and won the championship. The stable relationship between the VFF and domestic clubs is a strategic advantage. This allows coach Kim Sang-sik full freedom in personnel selection and thorough preparation for important matches.

However, being labeled the 'strongest team' also creates reverse pressure. If Vietnam fails at the FIFA ASEAN Cup 2026, public criticism will be harsher. Especially in the group stage format where only the group winner advances to the final, a draw or loss against Thailand on September 29 could eliminate Vietnam from the competition.

Tactical analysis – surprise from Thailand's B-team

A notable point: Thailand using a B-team at the ASEAN Cup 2026 was not an absolute weakness. In fact, they reached the final and caused difficulties for Vietnam. This shows that Thai football has impressive squad depth. Even without their brightest stars, they can still compete strongly.

From a tactical perspective, the uncertainty about Thailand's squad is a psychological weapon. Vietnam cannot know in advance who they will face, forcing them to prepare multiple plans. This could dilute focus and disrupt tactical preparation.

Prize money – new motivation from FIFA

The FIFA ASEAN Cup 2026 has a total prize fund of over $4 million, with the Division 1 champion receiving up to $1 million. This is a significant amount compared to previous regional tournaments. Additionally, FIFA has introduced match-based prize money for wins and draws. This creates a clear financial incentive for national teams and could give FAT more reasons to persuade clubs to release players.

However, for Thai clubs, this prize money may not be enough to compensate for the risk of losing players during the decisive phase of the season. The financial power of big clubs remains the biggest obstacle.

What scenario for the September 29 clash?

The match between Vietnam and Thailand in Group B is considered an 'early final' of the tournament. With only the group winner advancing to the final, the result of this match will almost decide the ticket to the next round. There are three main scenarios:

1. Thailand calls up their strongest squad: This is the ideal scenario for fans, promising a top-class match. Vietnam will face the biggest challenge.

1. Thailand still uses a B-team: Similar to the ASEAN Cup 2026, Thailand will continue to 'hide their cards'. Vietnam has a squad advantage but must be wary of the difficult opponent with deep squad depth.

1. Mixed scenario: FAT only persuades some clubs to release players, Thailand has a stronger squad than before but not the strongest. This is the most likely scenario.

Expert analysis

From a tactical analyst's perspective, Thailand 'hiding their cards' is not just a personnel issue but also a media strategy. The 'B-team' narrative becomes a shield: if they lose, they have an excuse; if they win, they are even more celebrated. But if Thailand loses with their strongest squad, the pressure on FAT and the head coach will be immense.

For Vietnam, winning the ASEAN Cup 2026 has placed them in the favorite's position. But football is not just about reputation. Vietnam needs to prepare for every scenario, from Thailand having Chanathip Songkrasin, Theerathon Bunmathan, to them fielding a young, unpredictable lineup.

Conclusion

The FIFA ASEAN Cup 2026 is not just a new tournament; it is a test of the strength of Southeast Asian football systems. Thailand may continue to 'hide their cards', but that does not diminish the intensity of the clash with Vietnam. On the contrary, it makes the match on September 29 even more intriguing. Can Vietnam defeat Thailand once again, regardless of what squad they bring? The answer will be decided on the pitch.
