Beyond the Trophy: Kim Sang Sik's FIFA ASEAN Cup Mission and Vietnam Football's Unsolved Equation

Busan, a July afternoon, I sat in my usual coffee shop near the harbor, my phone buzzing with notifications from the Vietnamese fan community group in Korea. They were animatedly discussing the draw, the opponents, and Kim Sang Sik's chances. One thing caught my attention: no one mentioned defending the title. Everyone talked about something further — about how the team would present itself before a tournament bearing the FIFA brand, before the eyes of the continent watching. I took a sip of coffee and recalled my own words from years ago: "Some lessons come not from victory, but from the jeers in the stands." Perhaps it was time for an entire football nation to listen to something deeper than the roar of victory. When Kim Sang Sik and his players set foot in Indonesia at the end of September, they will not just be playing for a trophy. The 2026 ASEAN Championship, the first tournament to carry the FIFA brand, running from September 24 to October 5 on Indonesian soil, is a watershed test. The ASEAN Cup victory earlier this year affirmed their status as the region's number one, but as the in-depth analysis I have in hand points out, that very dominance is concealing gaps yet to be filled. Over the past two years, Vietnam entered most matches as favorites, and that has made both weaknesses and strengths difficult to identify. This is the favorite's dilemma — dominant regional results obscure structural vulnerabilities that only emerge against superior opposition. "Three times I mispronounced a defender's name, and I learned to listen before writing." My words, forged during the 2026 World Cup, have never been more poignant. When I listen to what Kim Sang Sik shares, I realize: he is not talking about maintaining the crown, but about finding "more solutions." That is the clearest signal that the Korean coach is facing a much bigger equation than defending a title. The current tactical system may operate smoothly in a possession-dominant regional context, but can it withstand transition-heavy, high-pressing opponents like Japan, South Korea, or Iran at the 2027 Asian Cup? The answer, as Kim himself implies, is not yet. And this FIFA ASEAN Cup is precisely the controlled laboratory to find that answer. The 12-day tournament with its dense match schedule — a match every three to four days — will be a real test of squad depth. This is not my speculation, but the natural logic of a cup tournament. Kim Sang Sik has clearly stated he wants to "reassess his team's strength, from the quality and depth of the squad to how effectively his system operates." In such a tournament, squad rotation is not a choice but a necessity. Injuries, suspensions, fatigue — all will surface in a truly competitive environment where there is no room for leniency. Thus, this tournament is not only an opportunity to test the squad, but also a chance to see whether young players have the mettle to step up when given the opportunity. But there is a deeper story the analysis reveals, and I believe this is something not every fan sees. It is the potential contradiction between Kim Sang Sik's experimentation agenda and the fans' expectation of a final appearance. On one hand, he needs to use this tournament to experiment and evaluate — a process that may cause the team to perform less smoothly in the group stage. On the other hand, as defending champions, anything other than reaching the final will be deemed a failure. This is the champion's trap — having to win to save face while needing to experiment to grow. And in football, these two goals rarely go hand in hand smoothly. I remember the summer of 2026, when I wrote a profile for Park Min-jun, a young midfielder at Busan IPark. He was struggling under the weight of expectation after Leeds United came calling. Instead of just reporting, I organized an online Q&A for 500 fans, who sent personal video messages of encouragement. By season's end, Park signed a 4-year contract with Club Brugge. The lesson I drew from that story: the pressure of expectation can kill talent if not managed properly. And that is exactly the challenge Kim Sang Sik faces with the Vietnam national team right now. He needs to manage not just tactics, but the psychology of an entire collective expected to win. Indonesia, as hosts, poses the greatest threat. Not just because of home advantage, but because Indonesian football is on a rapid rise with quality naturalized players and well-invested infrastructure. For a rising team, playing at home before tens of thousands of passionate fans, beating defending champions Vietnam would be a statement. This is a perfect storm scenario for an upset. I have witnessed too many matches where favorites fell because they underestimated opponents in a hostile atmosphere. And I believe, if there is one team that can spring a surprise at this tournament, it is Indonesia. However, the most interesting thing the analysis reveals — and what resonates most with me — is that Kim Sang Sik is trying to shift the reference point of an entire football nation. When the article states Vietnam has "relatively little left to prove at regional level," that is not just an observation; it is a strategic declaration. Vietnam is transitioning from the mentality of a Southeast Asian team to that of an Asian team. This demands not just tactical changes, but a shift in psychology, in self-perception, and in how to prepare for greater challenges. And this FIFA ASEAN Cup, with the FIFA brand presence, is the opportunity for the team to begin acclimating to the pressure of a bigger stage. "92 days of diary away from the pitch, to know where one belongs." During the 92 days of the pandemic in 2026, I learned that distance is not a barrier but an opportunity to look back. And perhaps, for Kim Sang Sik, this tournament is also such a distance — a pause between two Asian Cups, to review where his team stands on the continental football map. Not at the position of Southeast Asia's number one, but at the position of a team seeking its place among Asia's mid-tier. And the biggest question is not whether Vietnam will win the FIFA ASEAN Cup, but whether after this tournament, the team will truly be stronger, have new solutions, and be ready for the bigger challenge at the 2027 Asian Cup. I still remember the image of Busan IPark players passing the ball to each other in the rain during the first match after the pandemic, in an empty stadium. That was the moment I understood that football is not just about winning, but about connection. And perhaps, what Kim Sang Sik is seeking at this FIFA ASEAN Cup is similar — not just results, but the connection between the pieces of the squad, between tactics and people, between present and future. As a 65-year-old who has witnessed so many ups and downs of Vietnamese and Korean football, I understand that the most enduring values come not from trophies, but from lessons distilled over time. And perhaps, this is the time for Vietnamese football to listen to those lessons. "The rhythm of the match lies not in the ball, but in the silence between two passes." The silence between two passes of the Vietnam national team right now is the period from the ASEAN Cup to the 2027 Asian Cup. And the 2026 FIFA ASEAN Cup is that silence — a meaningful pause where the team can listen to itself, reassess its strength, and prepare for the next leap. Will Kim Sang Sik capitalize on this pause? Can the team turn experiments into real strength? And will the fans have enough patience to wait for this process to complete? These are questions only time can answer. But one thing is certain: for Kim Sang Sik, this tournament is not just about the trophy. It is about building a solid foundation for the future. And that, in my view, is his true mission at this FIFA ASEAN Cup. From Busan, where I have lived and worked for nearly half a century, I continue to follow every step of the Vietnam national team. And I believe that, whatever the results, the lessons from this tournament will be the most valuable luggage for Vietnam football's journey to conquer Asia. Because, as I often tell the young journalists I mentor: "The beat keeper doesn't need to drum loudly, just at the right time, in the right place, and with enough love for the craft to stand long." And Kim Sang Sik, to me, is keeping the beat at the right time and place for Vietnamese football.
