Beyond the trophy: Kim Sang Sik's FIFA ASEAN Cup mission

On a January night in 2026, My Dinh National Stadium erupted in a sea of red and yellow. Vietnam had just defeated Thailand in the ASEAN Cup final, clinching their third Southeast Asian title. Tears, embraces, fireworks – all painted a perfect picture of victory. But behind that euphoria, a big question loomed: does this trophy truly reflect Vietnam's footballing strength, or is it merely a veil hiding unexamined weaknesses? Entering the FIFA ASEAN Cup 2026, held for the first time in Indonesia from September 24 to October 5, coach Kim Sang Sik is not simply chasing another title. The South Korean tactician faces a far bigger mission: turning this tournament into a comprehensive test for Vietnam's continental ambitions. Over the past two years, Vietnam have entered most matches as overwhelming favorites. Regional dominance has made the team's strengths and weaknesses difficult to identify. As I often say: "A shining ASEAN Cup can obscure a dossier full of doubts." Beating weaker opponents does not confirm true class. The real question is whether Kim's tactical system can function smoothly against stronger, faster, and more disciplined opponents at the continental level. Kim understands this better than anyone. In recent press conferences, he has repeatedly stressed the need to "experiment and carefully assess different options, giving Vietnam more solutions when facing stronger opposition." That is an admission that the current squad lacks Plan B and Plan C when encountering deadlock. In matches against other Southeast Asian teams, Vietnam usually dominate possession, but when facing physically superior and faster Asian sides, the high-pressing and quick-counterattacking puzzles remain unsolved. The FIFA ASEAN Cup 2026 is the perfect laboratory to solve that puzzle. With 12 days of intense competition, playing every 3-4 days, the tournament will rigorously test squad depth – an aspect Kim has repeatedly expressed concern about. Moreover, playing away in Indonesia, with one of the most passionate crowds in Southeast Asia, will be an important psychological test for young players. I come to the stadium to watch the game, but I stay to read the numbers. And the most telling number here is the gap between expectation and reality: a team touted as having "little left to prove at regional level" yet never having advanced past the group stage of the Asian Cup in modern history. Kim's biggest challenge lies not in opponents, but in the pressure from public opinion. Vietnamese fans are accustomed to winning. They expect the team to reach the final, even win the title. But if Kim uses this tournament to experiment with new personnel and different tactical formations, results may not meet expectations. This is a classic football paradox: when you are champions, every defeat is seen as a disaster, even if the real goal is long-term development. As I have said: "Titles on paper are a story; progress in reality is a verdict." Kim is facing that verdict. However, from another perspective, accepting the risk of experimentation in a regional tournament is entirely reasonable. If not now, then when? The 2027 Asian Cup, the most immediate major objective, will take place just months later. Kim needs real-match data to make final personnel decisions. A semi-final loss at the FIFA ASEAN Cup that uncovers a new central midfielder capable of controlling the game's tempo is far more valuable than a meaningless victory over a weaker side. That is why I appreciate Kim's approach: he is not swayed by the glamour of titles but focuses on building a team capable of competing at the continental level. Indonesia, as hosts, will be Vietnam's most dangerous opponent in this tournament. The fervor of home fans, combined with the country's remarkable football progress in recent years, presents a genuine challenge. But such challenges are exactly what reveal hidden weaknesses. If Vietnam can overcome away pressure and handle quick counterattacks well, that would be a positive signal for continental ambitions. Conversely, if the team crumbles under psychological pressure, Kim will have a clear answer about what needs improvement. Tactically, I expect Kim to experiment with various formations, from 3-4-3 to 4-2-3-1, and give opportunities to young players in key positions. What matters is not the result of each match, but how the team operates in different situations: when trailing, when playing with ten men, when facing high pressing. These scenarios rarely occur in regional matches where Vietnam usually control the game, but they will be common at the Asian Cup. Another point to note: the FIFA ASEAN Cup 2026 is scheduled within the FIFA international window, ensuring clubs release players. This means Kim will have the strongest squad, including overseas-based players. This is a rare opportunity to assess the combination of domestic and foreign-based players, a crucial element for the upcoming Asian Cup campaign. Ultimately, I want to emphasize that the FIFA ASEAN Cup 2026 is not just a tournament to defend a title. It is a comprehensive examination of Vietnam football's managerial, tactical, and psychological capabilities. Kim Sang Sik is leading the team through a crucial transitional phase: from a regional powerhouse to a continental aspirant. His success will not be measured by a championship trophy, but by whether the team can demonstrate its character and identity when facing bigger challenges. And as I often say: "I come to the stadium to watch the game, but I stay to read the numbers." For Kim, those numbers are not on the scoreboard, but in the progress of each player, the flexibility of each tactical setup, and the adaptability of the entire collective under different pressures. That is the true measure of his mission beyond the trophy.
