Coach Kim Sang-sik Returns to South Korea After Father's Death: Human Signal and Tactical Preparation Challenge Ahead of ASEAN Cup 2026

The stands of My Dinh stadium that evening were unusually quiet — not because the match had ended, but because the entire Vietnam national team coaching staff had just received sad news from Seoul. Coach Kim Sang-sik, who has been affiliated with Vietnamese football since May 2026, silently packed his bags to fly back to South Korea, where his 84-year-old father had passed away after a long period of illness. In a brief letter to the Vietnam Football Federation (VFF), the Korean coach informed them of his father's passing and expressed his wish to return home for approximately one week to handle funeral arrangements. The VFF's response did not come from a distant spokesperson, but from the federation's President himself — who personally encouraged coach Kim to return home the very night the news was received. That moment reflected the nature of the relationship between the two parties: not merely an employment relationship, but a bond between people jointly navigating Vietnamese football through winding paths. Football, typically known as a cold sport counted only in goals and points, once again showed that it is operated by flesh-and-blood human beings with personal griefs that no tactics can compensate for. To understand why this event carries particular weight, one must look back at the journey that coach Kim Sang-sik has built in Vietnam over more than two years. He arrived in Vietnam in May 2026, taking over the hot seat from a period when the national team was waiting for new wind. Within a short period, he was entrusted not only with the national team but also with the U23 squad — a move showing nearly absolute trust from VFF. Initial results arrived: the U23 Vietnam under his guidance delivered impressive performances at regional and continental tournaments, and the national team maintained stable momentum in qualifiers and friendlies. The VFF's narrative did not say much about tactics, but the way they affirmed that Mr. Kim had "focused heavily on his work, guiding Vietnam's U23 and senior national teams to strong results in regional and continental competitions" showed an implicit recognition they reserved for a coach who had almost completely devoted his time and mind to Vietnam. That is precisely why this departure, though lasting only about a week, cannot be taken lightly by experts. The tournament context makes the story even more sensitive. The FIFA ASEAN Cup 2026, the Southeast Asian regional tournament, will take place from September 24 to October 5 — meaning there are less than two weeks until the official schedule. The Vietnam national team is in Group A alongside Thailand, the Philippines and Pakistan, a group that analysts consider quite favorable with Thailand viewed as the direct competitor for first place, while the Philippines and Pakistan are opponents Vietnam can theoretically overcome. The period from now until the opening is therefore the final preparation phase — where tactical drills, the construction of game plans for each specific opponent, video analysis sessions, and set-piece training must all be carried out systematically. The absence of the head of the coaching staff for about 5 to 7 days, though not too long a period, falls precisely at a stage where every tactical decision carries great weight. VFF's response to this event demonstrates a lesson in sports governance that many regional federations have not truly internalized. Rather than maintaining a cold institutional attitude, or worse, implying that match results are more important than personal grief, VFF chose a response that is both principled and humane. The federation president personally sent condolences and encouraged coach Kim to return home as soon as possible, while committing that related work would be coordinated during his absence. The language used in the official announcement is also noteworthy: rather than referring to performance pressure or training schedules, VFF chose words of pure empathy, emphasizing that they hope coach Kim and his family can find the strength to get through this immense loss. That is the kind of communication that, in many Western football environments, managers had to spend years debating with the media to learn. VFF, in this case, chose the right path without needing any public debate. However, behind that empathy, the tactical equation still raises questions that are not easy to answer. During the week coach Kim is absent, who will be responsible for daily training sessions? If it is the assistant coaches, will they have sufficient authority and credibility in the dressing room to maintain training intensity and tactical discipline according to the direction the head coach had set? In modern football, national teams often have stable assistant staff, but the absence of the leader — especially a coach with a high-control style like coach Kim — always creates a certain power vacuum. Players, though respecting assistants, may still react differently when missing the person who gives the final direction. And when the coach returns after handling funeral arrangements, another question arises: will he still have sufficient clarity and focus to make sharp tactical decisions in a tournament where one wrong step may cost the entire campaign? The psychological element in this case needs to be taken more seriously than sports journalism typically does. Sports psychology has clearly documented that the grieving period after the loss of a loved one can significantly affect decision-making ability, concentration level, and even pressure tolerance of individuals — even those who have trained themselves over decades in professional environments. Moreover, this is not a sudden loss situation but the result of a prolonged illness process — according to information recorded by VFF and South Korean media, coach Kim's father had health problems for a period. This may imply that coach Kim has gone through a stage of "anticipatory grief" — the psychological preparation for the departure — and may help him handle the shock better than a sudden event. However, this remains speculation, and the actual reaction of each individual in such circumstances cannot be accurately predicted. Another angle that few people mention: the South Korean media, especially major sports newspapers, may follow this story from a completely different perspective. They may tell the story of "a Korean coach who has devoted himself to Southeast Asian football and is now facing a family tragedy" — a humane perspective that could create empathy at home. But questions may also arise from Korean public opinion: should coach Kim prioritize his career at a regional tournament over family at this time of grief? That question, if it arises, could create a certain psychological pressure that VFF and Vietnamese players will not directly see but could still indirectly affect. This is the type of cross-border impact that modern football administrators must consider when working with foreign coaches, especially those coming from football nations with active media like South Korea. The biggest question experts need to ask in the coming week is not "who will replace coach Kim for the next 5 days of training," but "when he returns, what state will the Vietnam national team face their coach in?" This is a question with no ready-made answer. Pre-tournament press conferences, interviews after coach Kim returns to Hanoi, and especially how he reacts on the touchline in the first match of ASEAN Cup 2026 will be the most important signals. If his tone in interviews is slightly more subdued than usual, if his eyes look more tired, that is not a sign of weakness — that is a sign of a person who has gone through loss and is trying to stand up to continue the mission he accepted. And to a certain extent, that very sobriety may become a source of inspiration for the players — who typically respond best when the coach shows authenticity and closeness rather than cold, purely technical detachment. ASEAN Cup 2026, according to expert assessments, is a tournament where Vietnam should set a target of at least the semi-finals — a completely reasonable expectation considering the group and current squad quality. Group A with Thailand, the Philippines and Pakistan is not an easy group but also not too difficult a group. Thailand, Vietnam's biggest opponent in the group, remains a real challenge, but in recent years the gap between the two teams has narrowed significantly. If coach Kim Sang-sik can overcome this personal phase and maintain the necessary clarity, the Vietnam national team is fully positioned to set higher goals than merely getting through the group stage. His story in the coming week will not only be the story of a coach returning from funeral arrangements — but also the story of how a person can transform personal loss into spiritual energy for an entire collective. And that, perhaps, is the greatest lesson that football — the sport supposedly counted only in cold numbers — can offer all of us this week. On a broader level, coach Kim Sang-sik's personal event is also a small test for the entire Vietnamese football system. When the head of a coaching staff must face personal tragedy, the way the organization responds will say a great deal about the nature of relationships between parties — not only institutionally, but also humanly. VFF in the past week has shown that they are willing to put people before schedules, and that is a positive signal that many regional football federations need to learn from. The Vietnam national team, with all its pressure and expectations, remains a collective of human beings that needs to be treated with respect — and that lesson is perhaps more important than winning a regional tournament. In the coming days, when coach Kim returns to Hanoi and enters the final preparation phase for ASEAN Cup 2026, all that Vietnamese football can do is give him support, patience and the necessary space to find his balance again. The rest will be answered by the pitch.
