Three Latecomers and a Standard Being Rebuilt: Discipline in Vietnam's National Team Under Kim Sang-sik

Late afternoon at the team's training center, the sound of studs striking the hallway floor echoed urgently. Three figures hurried past the row of meeting rooms, trying to turn the door handle as quietly as possible, but lateness is never truly silent. Nguyễn Filip, Nguyễn Thành Chung, and Trương Văn Thái Quý barely caught their breath before the meeting room door closed behind them. No one looked at the clock, but the whole team knew. And then, the decision came: disciplinary action. No specific fine was announced. But the way the coaching staff handled three latecomers — including a goalkeeper with dual heritage, a cornerstone center-back, and a quiet midfielder — revealed something far larger than a few minutes off schedule. It revealed a standard being rebuilt under head coach Kim Sang-sik. The context is far from simple. This is the preparation phase for the AFF Cup 2026, a tournament where Vietnamese football has set its sights on reclaiming the throne. The South Korean coach had just brought the team back from a training camp in South Korea. The atmosphere was tense, pressure was mounting, and a collective was being tested by fire. In that context, three players arriving late to a meeting — even if only by a few minutes — was treated as a violation of team discipline. According to sources from the Vietnam Football Federation, the coaching staff has agreed on the form of discipline. The penalty has not been officially announced, but it is highly likely to include a fine and possibly not being registered to play in the opening match. This means all three names could be absent from the starting lineup or the registered squad list in the first match of Group B at the AFF Cup 2026. Those present at the meeting that day recalled that Kim Sang-sik did not raise his voice. He simply looked at the three players, waited for them to sit down, and then told the whole team that at the national team level, punctuality is the bare minimum of professionalism. No one was thrown out of the meeting room. But the way the three players kept their heads down for the rest of the meeting, according to a coaching staff member, was more memorable than any punishment. From a professional perspective, the absence of a center-back like Thành Chung in the opening match will force the defensive line to reorganize. For Nguyễn Filip, a goalkeeper with excellent reflexes and good ball-playing ability, his absence between the posts would reduce confidence in build-up play from the back. Nevertheless, the coaching staff's decision demonstrates a clear philosophy: discipline is non-negotiable. This story goes beyond three individuals. Under previous coaches, there were hardly any cases where three key players were disciplined at the same time for lateness. Most incidents were handled internally, gently, with verbal warnings and symbolic fines. Kim Sang-sik's decisive handling is sending a message: no one is bigger than the collective, and no one is exempt from the most basic rules. For Nguyễn Filip personally, this is a major test. The goalkeeper, born in 2026 in the Czech Republic and once a Czech youth international, carries both football cultures within him. When he returned to wear the Vietnam jersey after gaining citizenship, Filip didn't just change nationality — he bet his entire career on a collective trying to find itself again. The moment he was late to that meeting might be a minor note in the symphony of a promising career. As for Nguyễn Thành Chung, the defender born in 2026 who plays for Hà Nội FC, he is one of the rare Vietnamese players who can perform well in a three-center-back system yet remain mobile enough for a two-center-back setup. In the national team jersey, Thành Chung has always been one of the first to arrive at training. That is why his lateness surprised many. Trương Văn Thái Quý, a 27-year-old midfielder, receives less media attention than his two Hà Nội FC teammates. But it is precisely the quiet players like him who are crucial links in a collective. Thái Quý reads the game well, escapes pressure effectively, and maintains the rhythm of play with short, safe passes. Without him, the national team's midfield loses a balancing option. Data from recent Vietnam national team matches shows that defensive stability depends heavily on adaptability. In the last 10 matches, the team conceded an average of 1.2 goals per game. That figure is not bad, but it is not enough for full confidence. When opponents possess fast, technically skilled players — common in Southeast Asian teams — the absence of an experienced center-back like Thành Chung in the early matches could create gaps that are hard to fill. Looking further ahead, this disciplinary story raises a bigger question: where exactly is the Vietnam national team on its rebuilding journey? After ups and downs, Vietnamese football is confronting a generation of players who have talent but have not yet been truly forged in discipline within a brutally competitive environment. Fines, decisions to leave players unregistered, stern meetings — all are bricks in building the team's cultural foundation. One detail few noticed: during that afternoon meeting, Kim Sang-sik spent the final 10 minutes talking about how players eat, rest, and use their phones. He compared the team to a business, where everything must operate according to process. This approach, rooted in Korean football culture, is gradually seeping into the Vietnam national team. There is a truth that not every fan recognizes: Kim Sang-sik is not just building tactics — he is rebuilding values. The opening match against Laos at the AFF Cup 2026 will be a test for an entire system, including how the three latecomers respond to discipline. If they return stronger, this could be a turning point. If they sink into frustration, it will be the first crack in a collective trying to find itself again. In the locker room after this afternoon's training session, Nguyễn Filip — the last to leave the field — stood still looking at the empty stands, where thousands of supporters will sit this weekend. He told a coaching staff member: "I don't like being punished, but I understand why I was punished." That answer, from someone who has witnessed many generations of players rise and fall, is a good sign. Football is never just football. Discipline is never just punctuality. And the Vietnam national team, with three latecomers and a standard just erected, is showing that they understand this. The remaining question is whether this lateness is the final stumble, or the turning point for a collective to grow up. In the coming days, I will watch how those three individuals respond. Not to judge, but to understand more about a generation trying to find itself under a harsher philosophy. At 54, I have witnessed many collectives fall apart for lack of discipline, and not a few grow stronger through cold decisions. Which way the scale tips, only time and matches will answer. The AFF Cup 2026 will be the stage for this story. Where three latecomers can become symbols of redemption, or lessons about the price of letting old habits rule. And above all, it will be the story of how a team can change its destiny not just through tactics, but through attitude. When the ball rolls, people see victory. But before the ball rolls, people see the true substance of a collective. And for Vietnam's national team right now, that substance is measured by how three players handle one late afternoon.
