Kim Sang Sik and the Challenge of Escaping the 'Champion's Trap' at the FIFA ASEAN Cup 2026

I have followed Southeast Asian football for 35 years, and I have never witnessed a moment as strange as this: a national team that has just been crowned regional champions, yet instead of enjoying the glory, is facing the biggest question about itself. Coach Kim Sang Sik's Vietnam team is facing a paradox: they are Southeast Asian champions, but that very title is masking weaknesses that have never been tested at the continental level. When FIFA decided to directly sponsor the Southeast Asian championship and name it the FIFA ASEAN Cup 2026, to be held in Indonesia from September 24 to October 5, 2026, they created a completely new playground. This is the first time the regional tournament has been organized directly by FIFA, bringing with it substantial prize money and the opportunity to improve FIFA rankings. But for Vietnam specifically, this tournament carries a much deeper meaning than just another regional title. After winning the ASEAN Cup 2026, Vietnam has proven their status as the number one team in Southeast Asia. But this very dominance creates a subtle problem: over the past two years, when Vietnam entered most matches as heavy favorites, their strengths and weaknesses have not always been easy to identify. Regional opponents often play with deep defensive blocks, meaning Vietnam's defensive transition is rarely truly tested. Victories against weaker opponents may be masking structural vulnerabilities that only emerge when facing much stronger teams like Japan, South Korea, Iran, or Australia. Kim Sang Sik, the South Korean coach, understands this well. He does not view the FIFA ASEAN Cup as an opportunity to defend a title, but as a controlled tactical laboratory. The immediate target is reaching the final, but his real goal is much bigger: reassessing the team's strength, from the quality and depth of the squad to how effectively his system operates. He needs to experiment and carefully assess different options, to have more solutions when facing stronger opposition at the 2027 Asian Cup and World Cup qualifiers. The 12-day tournament with a dense match schedule, with each match only 3-4 days apart, creates a high-intensity competitive environment. This is the perfect test for squad depth – one of the potential weaknesses Kim needs to evaluate. Rotating the squad and testing different personnel combinations will not just be tactical, but a practical necessity in a context where fitness is constantly challenged. But there is an inevitable tension between these two goals. If Kim prioritizes experimentation and Vietnam performs poorly in the group stage, the reaction from public opinion could be severe. The expectation of a final appearance will create significant psychological pressure, especially since Vietnam are the reigning champions. This is a classic 'process vs. results' conflict in football management – and Kim is walking a tightrope between these two objectives. Indonesia, as hosts, represents the biggest threat. Home advantage with the passion of their fans, combined with the rapid development of their football in recent years, creates a perfect storm for an upset. If the two teams meet in the knockout stage, it could be the tournament's most dangerous fixture for Vietnam. I once stood before data tables and felt like I was witnessing a miracle at Anfield, but here, the data tells a different story. Vietnam has dominated the region, but that dominance has never been tested at a higher level. The question is not whether Vietnam will win the FIFA ASEAN Cup, but whether they dare to accept the risk of experimentation to prepare for the bigger challenges ahead. Those who are right before their time always pay the price of solitude, and Kim Sang Sik may be paying that price right now. But if he succeeds, Vietnam will not just have another trophy – they will have a team truly ready for the continental stage. The FIFA ASEAN Cup 2026 is not just a tournament – it is a turning point that will shape the future of Vietnamese football.
