When Kim Sang Sik Leaves the Bench to Mourn His Father: Seven Empty Days and Vietnam's Quiet Test

The day the Vietnam Football Federation issued its announcement, it ran only a few lines: head coach Kim Sang Sik was returning to South Korea to mourn his father. No press conference. No fanfare. Just a man stepping away from the technical bench for roughly seven days, at the very moment the national team entered the final stretch of preparation for the ASEAN Cup 2026, which kicks off on September 24. His father passed away after a long illness at the age of 84. In refereeing, that mistake in Russia years ago didn't teach me how to call correctly — it taught me how to live with the sound of my own whistle. One lesson I took from it: when you're forced to leave your position, what remains on the field isn't you — it's what you prepared beforehand. That principle holds for referees, and it holds for a head coach. The VFF received the news with rare empathy. The federation president personally encouraged Kim Sang Sik to return home, stressing that family matters most now. The official message expressed hope that he and his family would soon overcome their enormous loss. That was not a media move. It was how a football nation treats its coach when tragedy strikes. But here I want to weigh two things that are often rushed together: emotion and technical reality. We can feel for Kim Sang Sik, and at the same time look straight at the gap he leaves behind. Kim Sang Sik took the Vietnam head coach role in May 2026. Over more than two years, he ran the U23 and senior teams in parallel, earning results across regional and continental competitions. His work ethic is known for its high intensity. He spends most of his time on training plans, video analysis sessions, and building a playing philosophy. That makes the seven-day gap slightly more notable. Not because the team lacks a leader, but because of the timing. National team camps across Southeast Asia tend to compress tactical volume into short pre-tournament windows. A week during the final stretch is not an ordinary week. It is when shape-building drills, set-piece sessions, and opponent-specific plans get assembled. The ASEAN Cup 2026 kicks off on September 24. Vietnam sit in Group A with Thailand, the Philippines and Pakistan. In this group, Thailand is the direct rival for qualification, while the Philippines and Pakistan are rated lower. The draw is seen as moderately favorable. Public expectation, following the usual logic of Vietnamese football in regional tournaments, centers on advancing from the group and going deep. So what does that week actually cost? The answer depends on something the VFF announcement doesn't mention: the delegation structure within the coaching staff. In professional football, when a head coach is absent for personal reasons, assistants usually take over daily training. That's standard procedure. The issue isn't whether the team trains, but the quality of those sessions. An assistant can maintain fitness intensity and run familiar combination drills. But adjusting the plan session by session, reading players' reactions, and changing the curriculum mid-session — that work belongs to the man in charge. From my experience watching matches, one thing is rarely mentioned: a head coach's greatest value isn't in what he designs before the match, but in what he fixes during it. Preparation can be divided. Split-second decisions cannot. I've said this about VAR: it doesn't fix the match — it exposes how we define a mistake. A coach's personal crisis does the same. It exposes a collective's internal strength. One point needs clarity to avoid exaggerating the problem. A seven-day window falls within a manageable range. If Kim Sang Sik returns on schedule, he has about ten days before the first match to finish final preparations. Ten days for a regional tournament, with a squad built over more than two years, is not an alarming number. It's tight, but not fatal. Another dimension worth discussing is psychology. In professional sports psychology, losing a parent is documented as one of the most disruptive events for those in high-focus professions. The fact that his father was ill for a long time may have helped Kim Sang Sik prepare emotionally. But no preparation erases the real moment. In practical terms, Korean funeral rites typically last three to five days. Adding travel time, roughly one week is a sensible figure. That means, absent complications, Kim Sang Sik returns to Vietnam with about ten days of preparation before the opening match. That's enough time to reacclimatize, but not enough to fully compensate for what was missed. The question worth asking isn't whether Kim Sang Sik is professional enough to get through it, but whether Vietnam has a mechanism to hold the ship steady during the time he needs to stabilize. Here, the VFF's message is a positive signal. A federation that tried to exploit the crisis for pressure would cause its coach to lose focus. The VFF chose the opposite. This is where I want to step away from the familiar analytical path. When a head coach is absent, the media reflex is to look at the gap. But in national team football, there is an invisible thing only a gap can measure: how dependent a team is on the individual leading it. A national team that cannot stand on its own for a week already had a problem before its coach left. National teams, unlike clubs, don't have a long season to build structure. Their time together is counted in days. What holds them together when the leader is away? The answer lies in the system the head coach built beforehand, and in the discipline the senior players carry. Two risks need to be distinguished. The first is preparation risk, about the volume and quality of training. The second is psychological risk, about Kim Sang Sik's ability to focus when he returns. The first can be mitigated by clear delegation. The second is harder to control and depends on each individual's emotional recovery speed. Perhaps these seven days are a test no one wanted. It forces Vietnam to prove that Kim Sang Sik's imprint has soaked into how they work, not just into tactical meetings when he's present. That's a hard result to measure, but more important than a friendly win. In refereeing, I've seen many teams that only know how to stand when their leader is on the field. They collapse not because they lost a man, but because they never had a system strong enough to run itself. There is something the offside trap can never catch: a player's intention. And there is something absence can never hide: the true strength of a system. One more thing about the human side, which analysis often skips. Kim Sang Sik is not Vietnamese. He comes from South Korea, works in a distant country, and now must return home under the heaviest circumstances. For someone in a profession where media and fans are always ready to dissect every decision, the empathy shown to him now is both a moral duty and a test of how a football nation treats the person it invited in. In the coming days, Vietnamese media will likely keep a sympathetic tone. Expectations for the ASEAN Cup don't change because of this gap. If the team goes deep, the story of Kim Sang Sik's resilience will be retold as a bright spot. If the team exits early, some will question the disrupted preparation — though a seven-day gap can hardly be the main cause. This is what I always remind myself when writing about controversies: don't turn analysis into a verdict, and don't confuse a gap with a deficiency. The ASEAN Cup 2026 kicks off on September 24, and Vietnam will enter the tournament with a week of training their leader missed. There are things the VFF cannot replace with any announcement. But there are also things a federation can do to keep the team steady while the man in charge is away. What needs watching isn't only the match results. It's how Kim Sang Sik returns: with what focus, with what decisions in high-pressure minutes. And it's how Vietnam stands when their whistle-blower briefly leaves the field. Football doesn't stop for anyone. But a football nation that knows how to stop for a person may go further than one that only knows how to run.
