Kim Sang Sik returns to South Korea after bereavement: A timeline Vietnam must record before ASEAN Cup 2026

The Vietnam Football Federation's (VFF) announcement, released on a midweek afternoon, ran only a few lines, with no figures and no roadmap. It confirmed that head coach Kim Sang Sik had returned to South Korea following the death of his father, aged 84. It was accompanied by condolences from the VFF chairman and a wish that the man in charge recover from his loss, with an expected return to Vietnam after roughly one week to attend the funeral.

For the ordinary reader, this is a purely sad piece of news and nothing more. For me, someone who has spent years recording the administrative and disciplinary decisions of football federations, that announcement is a timeline that must be preserved. Not to judge, but to cross-check. The gap it creates falls exactly in the most sensitive zone of a tournament cycle: the final preparation phase for the 2026 ASEAN Cup, which kicks off on September 24.

This is not a story about emotion. It is a story about how a national team operates when the head of its coaching staff is absent at the most important moment.

Context: Where one week sits in a preparation cycle

The 2026 ASEAN Cup has been confirmed to run from September 24 to October 5. Vietnam has been drawn in Group A alongside Thailand, the Philippines and Pakistan. On paper, Thailand is the direct rival for top spot, while the Philippines and Pakistan are rated lower. The match against Thailand is therefore treated as the decider for the group.

Kim Sang Sik was appointed in May 2026. Since then, he has led both the U23 side and the senior national team, guiding both to positive results in regional and continental competitions. This is the type of contract the sports-administration world calls a "full-control manager" - a coach granted decision-making power over tactics, personnel and training schedules, without sharing authority with an independent technical director.

When a figure with that much power leaves the team for a week, the question is no longer "is he grieving?". The question is "during those seven days, who makes the decisions?".

I have followed many cases of national team coaches going absent mid-cycle - for health reasons, for federation sanctions, for bereavement. What the cases that produced real consequences had in common was not the absence itself, but whether the team had a ready replacement structure. For Vietnam at this moment, the article provides no information on whether an assistant coach stepped in to run training. That is the first information gap to flag.

Core: Seven days, three questions, and one principle

Question one: How many real preparation days are lost

If Kim returns to Vietnam after about a week, his direct preparation time before the first group match is shortened accordingly. For a Southeast Asian national team, pre-tournament preparation is typically compressed into short, concentrated windows - usually two to three weeks, with the final week reserved for finalising the tactical scheme, assembling the starting eleven and rehearsing set-piece situations.

Losing a week in that budget is not a catastrophe, but it is not small either. If the coaching staff had planned opposition video analysis sessions or set-piece drills for exactly this week, that work must be pushed to the following week or cut. The core point is this: the damage is not measured in days absent, but in specialised sessions compressed or skipped.

A week of a coach who controls the entire workload differs from a week of a coach who only appears at key tactical sessions. Under a full-control model, the absence of the decision-maker creates delay at every link, including small matters such as confirming the squad list or adjusting intensity.

Question two: Who keeps the rhythm during those seven days

This is the point the VFF announcement does not answer. In the standard operation of a national team, when the head coach is absent for personal reasons, the coaching staff is usually split into two tiers: the daily operational tier (usually run by the number-one assistant) and the tactical decision tier, which waits for the head coach's return.

This split matters because it determines the quality of sessions during the absence. If the assistant merely maintains fitness intensity and basic combination drills, the team loses little. If the assistant tries to replace the head coach by introducing new tactical decisions, the team can fall into a waiting state - training in one direction, then having to retrain in another when the skipper returns.

I have witnessed this phase mismatch many times. It does not show up in the match report, but it shows up in the first ten minutes of the first match of a tournament. A team that trains in the wrong direction for a week often needs the first twenty minutes to rediscover its structure.

Question three: Which rules permit and limit this

Here I must state my professional view clearly. The same situation, two ways of blowing the whistle - the law is never ambiguous, only the person holding the whistle is. FIFA and most national federation regulations permit a coach to take leave for family reasons, especially bereavement. The VFF's swift and public approval is the correct administrative handling.

But "permitted" and "prepared for" are two different things. A professionally operated federation does not simply say "we agree to let you go". It must also answer beforehand: if the decision-maker is absent during the crucial week, what is the contingency plan, who signs off on the list, who is responsible if there is an error in the player registration stage.

No federation discloses these details publicly. But the existence or absence of them will be revealed in the final stretch. Discipline is not for punishment, but so the match can continue. Here, administrative discipline is what keeps the preparation machine unbroken when its head is absent.

Squad depth: The variable is not the coach's chair

Another angle - and in my view the more important one - reverses the question: whether a single week of head-coach absence really threatens Vietnam's group-stage results at the tournament.

Looking at Group A, Vietnam are rated above the Philippines and Pakistan. These are two opponents against whom the quality of Vietnam's squad can compensate for shortcomings in tactical preparation. The match against Thailand is the real test.

The five-substitution rule - widely adopted after the pandemic period - helps teams with squad depth rotate better, but at the same time turns the final twenty minutes into a war of attrition. For a team with as many quality bench options as Vietnam, five substitutions are an advantage. But that advantage only materialises when the coaching staff proactively plans rotation in advance. A week of absence by the planner can delay the rotation options, and the team enters the match with a near-fixed lineup.

I recall the pandemic period, when tournaments applied different substitution rules and created a clear inconsistency between competitions. The pandemic taught me that laws also need to breathe. But it also taught me something else: once a law opens up a space for flexibility, the team that prepares for that space wins, and the team that does not runs out of steam at the end. Kim's absence during the week of rotation planning is a minor disadvantage, but it falls exactly where the price is easiest to pay.

Group A: Re-reading the order of priorities

The group landscape for Vietnam does not change because of an administrative announcement. Thailand remains the main rival; the Philippines and Pakistan remain two must-win matches. What changes is how resources are allocated within the team.

With a coach in mourning, it is likely he will approach the decider with more caution - not because he is weakened, but because people tend to seek safety in their work when under emotional pressure. A more balanced, less risky scheme may be the natural choice. Yet in Group A, caution against the Philippines and Pakistan could cost Vietnam points in matches that should be won comfortably.

A high defensive line is a wager; I only record the moment the gambler turns over his cards. For Vietnam, the strongest opponent in the group - Thailand - is a team well capable of punishing gaps behind the defensive line. How Vietnam organises its defensive block in that match will show whether Kim has returned with his usual sharp decision-making.

The psychology of the decision-maker

A coach cannot be analysed like an injured player. There is no gauge to show whether he has recovered. But one point can be stated firmly: Kim's father died at 84 and, according to accompanying information, had prior health problems. This suggests the family had somewhat prepared psychologically for the loss - the phase sports psychologists call "anticipatory grief".

Anticipatory grief does not make the loss lighter. It only makes the initial shock less sudden. Functionally, he may return to work faster than after a sudden loss. But the ability to concentrate intensely in high-pressure decisions - a substitution at minute 70, a mid-half adjustment to the scheme - remains an unknown that cannot be verified from outside.

I always trust the naked eye when observing a match. But years of following refereeing decisions have taught me that the naked eye can also lie, especially when the observer already has a story in his head. With Kim, I will not read his touchline gestures to guess his psychology. I will read the timing of substitutions and the allocation of his substitution windows.

Precedent and consistency

From an administrative standpoint, the VFF's handling of this event sits in the "favourable" category - where the federation proactively accommodates and the coach transparently explains his reason. Favourable cases usually leave no trace in the record. But they are still worth recording, because they set a precedent for later.

The first mistake is not for erasing, but for cross-checking later. The reverse is also true of good handling. How the VFF treats Kim this week will be recalled if, a few months from now, another coach of a youth national team faces a similar situation. Consistency in how people are treated is the measure of a sports organisation's maturity, more than any trophy cabinet.

A contrarian angle: Sympathy can obscure a question

This is the part I must state plainly, even if it is not easy to hear.

When a coach is absent for bereavement, the media atmosphere immediately shifts to sympathy. Journalists report respectfully, fans express condolences, and any technical analysis of the schedule gap becomes hard to voice. That is correct in human terms. But professionally, universal sympathy can obscure a question that needs to be asked: will Vietnam's results at the 2026 ASEAN Cup be judged on actual strength and preparation work, or on the emotional context surrounding the head coach?

I do not raise this question to lessen the pain of a son who lost his father. I raise it because it is the only way to keep every assessment fair.

There is a paradox in how the media handles stories like this. When results are good, the story told is "extraordinary resilience in overcoming loss". When results are poor, the story is often excused: "the hardship was too great, blame cannot be assigned". Both narrative modes centre on emotional context and avoid analysing the actual preparation structure.

A robust sports organisation can bear both directions: it sympathises with the person and still evaluates the work professionally. The VFF has demonstrated the first leg correctly. The second leg will only be revealed once the tournament begins.

There is a second, subtler paradox. The VFF's swift approval does not necessarily reflect perfect professionalism. Sometimes it simply reflects a reality: national team coach contracts in Southeast Asia often lack tight binding clauses on the obligation to attend sufficient preparation sessions. When there is no binding clause, administrative "generosity" becomes much easier than when there is. This is something no announcement will state.

Conclusion: What to track, not what to sympathise with

I believe Vietnamese readers have given Kim Sang Sik enough sympathy, and that is right. What remains is to track three specific signals over the next two weeks.

First, whether Kim returns to Vietnam exactly as expected. If it stretches beyond one week, the question of the preparation gap moves from small to significant.

Second, what the reported training sessions focus on during his absence. If it is fitness and basic combinations, the rhythm is kept. If there are signs of tactical changes introduced by an assistant, the odds of a week of training in the wrong direction rise.

Third, how substitution windows are allocated in the first group match. This is the clearest professional signal of whether the coaching staff has prepared enough depth.

Football does not lack touching stories, but a professional football nation is built on decisions that are recorded and cross-checked. Kim Sang Sik's case will not be remembered because it is sad, but because it forces us to answer a difficult question: when the leader is absent, is the national team's structure strong enough to replace him? The answer appears on the scoreboard, not on the announcement page.
