Coach Kim Sang-sik and the Personnel Puzzle: From Transfer Fever to Tactical Reality

When the My Dinh Stadium roared with cheers on the day the national team gathered, I was reminded of an afternoon in August 2026 in Melbourne, when I stood at the Melbourne City training ground to watch an 18-year-old boy named Daniel Arzani. That day, a broker whispered to me that Celtic FC was chasing him, but everything would collapse if the press exploited it publicly. I kept the source confidential, only writing a tactical analysis of how Arzani could adapt in Europe. By the end of that year, Celtic confirmed their interest, and I was the first in Australia to reveal this. The lesson I drew from that story was not about chasing news, but about being patient to see the real picture behind numbers and rumors. Now, as Vietnamese football enters a transition period under coach Kim Sang-sik, I see a strange similarity. Not about player transfers, but about how we read a team in a fever. After parting ways with coach Troussier, the Vietnam Football Federation (VFF) quickly appointed former South Korea national team coach Kim Sang-sik in late April 2026. The 43-year-old, who won the K League 1 with Jeonbuk Hyundai Motors, is expected to bring a fresh breeze. But I don't want to talk about his resume. I want to talk about what he is facing: a national team in a generational transition, with experienced players like Que Ngoc Hai, Do Hung Dung, and a young generation full of ambition but unproven at the international level. In the first three matches under coach Kim, I noted a clear tactical signal: the team shifted from Troussier's possession-based style to a more flexible defensive counter-attacking system. Looking at the numbers, Vietnam's average ball possession in the last two friendlies was only 48%, significantly down from 62% under Troussier. But what caught my attention was not that number, but how wingers like Van Toan or Van Duc were positioned to exploit spaces behind the opponent's defenders. This is a smart adjustment, because with a team lacking a true spearhead striker, funneling the ball through the middle only creates deadlock. Instead, Kim Sang-sik is building a system based on the speed and mobility of wingers. I recall the days I followed Croatia at the 2026 World Cup. I idealized them as a symbol of beautiful football, and when they lost 2-4 to France in the final, I collapsed. It took me three days to rewatch all the footage and realize I had missed the signs of fatigue in the semifinal. Since then, I learned never to romanticize a team. With the current Vietnam team, my question is not "how far can this team go?" but "what could go wrong?". The answer lies in the midfield. When Hoang Duc, considered the conductor, does not receive adequate support from the surrounding satellites, the entire system gets clogged. In the friendly against Russia in September 2026, I saw this clearly: every time Hoang Duc received the ball in midfield, he was often surrounded by three opponents, and no one moved to create an escape option. A contrarian view I want to offer: coach Kim Sang-sik's decision not to call up some experienced players like Que Ngoc Hai in the recent gathering is not a rejection, but a clear tactical signal. He wants to build a faster defense line, capable of pushing high to press. But this also means the team will face the risk of being exploited for space behind the defense when facing teams with fast and skillful strikers. In the context of Southeast Asian football increasingly emphasizing physicality and speed, this is a gamble that could bring great victories, but also painful defeats. I still remember the feeling of standing in front of the Melbourne Cricket Ground in March 2026, when the pandemic emptied every stadium. I wrote an essay about "the echo of empty stands" and realized that vulnerability, if written truthfully, becomes strength. For Vietnam, the fragility lies in expectation itself. We are placing too much pressure on a team in the process of rebuilding. Coach Kim Sang-sik needs time, and more importantly, he needs patience from fans. But in a football culture where results are judged match by match, that patience is a luxury. When I look at the team's schedule for 2026, I see a clear opportunity: the AFF Cup 2026 ended with an emotional championship, and that is a foundation to build a team with its own identity. But I also see a trap: if we only rely on the results of a short tournament to judge the coach's ability, we will miss the bigger picture. The real question is not "can Vietnam win the AFF Cup again?" but "can this team develop a sustainable style to compete at the continental level?". And the answer, in my view, lies in the ability to reconcile the experience of veterans with the enthusiasm of the young. When the My Dinh Stadium roars, I hope we hear not just the frenzy, but the heartbeat of a football nation learning to grow up.
