Vietnam face new test at FIFA ASEAN Cup 2026: Coach Kim's time puzzle

Late at night at the training center, I received a call from an assistant of Coach Kim Sang-sik. He didn't talk about tactics, but simply asked me: "Do you think seven days is enough to build a team?" I was silent. In three decades of following Southeast Asian football, I have never seen a national team enter a major tournament with such a tight schedule. The context of this story begins with a congested fixture list. Cong An Ha Noi (CAHN) - the club that has supplied most of the national team's key players - still has two important matches before the training camp begins: a Champions League Elite match against Osaka on September 15, and a V-League match against Dong Nai on September 20. Meanwhile, the Vietnam national team will play their Group B opener against the Philippines on September 26. This means CAHN players like Quang Hai, Dinh Bac, Nguyen Filip, Van Hau, Van Do, Thanh Long, Quang Vinh will only have about five or six days to integrate with the full squad before departing for Indonesia. Theoretically, Coach Kim has about two weeks to work with the entire squad. But in reality, with seven CAHN players arriving late, the actual time for complete preparation is significantly compressed. This is a major departure from previous ASEAN Cup cycles, when Kim had more favorable conditions and more time. The challenge is not just tactical, but also about the coach's adaptability when he no longer has the luxury of ideal preparation. From a professional perspective, the core challenge is not in tactical design. Kim's system - possibly a 3-4-3 or 4-3-3 with quick transitions - has been shaped over time. The problem lies in execution. Set pieces, pressing coordination, and positional discipline all require time to perfect. With CAHN players having only a few days of training, the team's cohesion in the match against the Philippines will almost certainly not be optimal. I remember the night of the 2026 World Cup in Russia, when I learned to listen from a goalkeeper who couldn't speak. Kasper Schmeichel, after saving three penalties but still losing, stood silently in the mixed zone. I didn't ask about tactics, but simply said: "Danish fans need to hear something to be proud of." He later told the press: "We didn't lose because of a lack of courage." That moment taught me that when a team falls apart, the writer's job is not to judge anyone, but to find the thread connecting players to their community. Now, with the Vietnam national team, I see a similar situation. Not a collapse, but a shortage of time. CAHN players come from a congested schedule: Champions League Elite with Osaka, then V-League with Dong Nai. They carry physical fatigue, while other players who have been in camp longer may have different fitness peaks. This asymmetry in physical readiness makes implementing a high-intensity pressing system risky. There's a detail few people notice: the original article emphasizes that Vietnam still has "several technical issues to improve following the ASEAN Cup 2026." This suggests pre-existing deficiencies, and with reduced preparation time, they are unlikely to be systematically addressed before the opener. This is a compounding risk: existing shortcomings plus new integration challenges. However, I want to offer a counter-intuitive perspective. Is the lack of time truly an absolute disadvantage? In modern football, sometimes tactical simplification is the key. When there isn't enough time to practice complex combinations, Coach Kim might be forced to shift to a more direct, transition-based approach, leveraging the speed of wingers. This could create a tactical surprise for opponents who have prepared for a possession-based Vietnam. Moreover, CAHN players come from a high-level competitive environment - Champions League Elite - where they have been tested at high intensity. This might give them a match sharpness that players who have only trained for a long period may lack. The issue isn't that they lack fitness, but that they need time to synchronize with new teammates. I remember the 2 AM call from Mino Raiola about Paul Pogba's transfer. He never talked about money; he always talked about power. Similarly, here, the story isn't just about training time, but about the power in scheduling. The Vietnam Football Federation (VFF) may have had to concede to CAHN's continental schedule, and the national team bears the consequences. This leads to a bigger question: does FIFA truly protect international windows? With FIFA's involvement in the ASEAN Cup, one might expect stricter enforcement of international match calendar regulations. But reality shows that clubs with commercial interests in continental competitions can still exert pressure on schedules. This is a structural issue that not only Vietnam faces. Returning to the match against the Philippines. This opponent is not a top Southeast Asian team, but they are expected to field their strongest squad. A poor opening match against a lower-ranked opponent would put enormous pressure on Coach Kim and the players. Conversely, a convincing victory would create positive momentum for the entire tournament. I believe Coach Kim will have to make a strategic choice: either prioritize defensive solidity or accept risks to attack. With limited training time, building an organized defense is usually easier than implementing complex attacking patterns. Set pieces and pressing coordination require the most rehearsal time, so Kim might prioritize stability over flair. But there's something I learned from the goalkeeper who couldn't speak: sometimes, silence and patience are the strongest weapons. Vietnam has a talented generation of players, and they proved it by winning the previous ASEAN Cup. The issue isn't whether they have the ability, but whether they have the time to show it. I remember the summer when football stopped breathing, when I drew maps to keep the small workers from being forgotten. In this context, the small workers are the CAHN players - those who have to carry both club and national team schedules. They are not celebrated heroes, but silent laborers, dedicating themselves to both jerseys. The signature dries, but the story of a deal lives on in phone calls. Similarly, the story of Vietnam's preparation will not only be written on the pitch, but also in closed meetings, phone calls between Coach Kim and CAHN's management, between VFF and clubs. That's where real power operates. When I look at the fixture list, I see an irony. CAHN plays in the Champions League Elite - a prestigious arena that brings money and fame to Vietnamese football. But that very arena creates a gap in the national team's preparation. This is a trade-off no one wants, but it's the reality of modern football. There's a question I always ask myself: are we being too harsh on Coach Kim? He won the ASEAN Cup, but now he faces a completely different challenge - the challenge of adaptation. Not everyone can build a winning team under non-ideal conditions. And that's exactly what this tournament will test. I don't belong to the coaching bench; I belong to the darkness between two offers. I can only observe, analyze, and tell the story. But I believe that, regardless of the outcome, the lessons about adaptation and time management will stay with Vietnamese football long after the tournament ends. Mino calls at midnight because he knows: the one standing in the middle of the market must be most alert when the market closes. Coach Kim is standing in the middle of the preparation market, and he needs to stay alert to make the right decisions in difficult circumstances. Can he do it? I don't have the answer, but I will watch. The map of influence that summer didn't save the world, but it kept a roof. Similarly, careful preparation, even if short, can maintain the faith of fans. And that's the most important thing in football - not winning or losing, but how we face challenges. When Vietnam steps onto the pitch against the Philippines on September 26, I will not just look at the score, but at how they move, how they coordinate, and how they handle difficult situations. That will be the true measure of their adaptation. And regardless of the result, I believe the small workers - the CAHN players, the logistics staff, the preparation personnel - will not be forgotten. Because in the end, football is not just about the stars on the pitch, but about the silent people behind them. And that's the story I want to tell.
