The Beat Behind V.League: Where Vietnamese Football Actually Builds Its Squad Depth

I still remember an afternoon in March 2026, standing at the edge of a youth training pitch in northern Vietnam. The air was humid, the grass wet, and a group of U17 players were running the final laps of a fitness drill. None of them appeared on the transfer feed. No fan pages, no sponsorship deals, no names on the evening bulletin. But it was there, in the silence of a training session without spectators, that I began to understand what every V.League table overlooks. Vietnam's squad depth is not bought in the transfer window; it is grown on afternoons like that one. The first steps taken on a training pitch never make the transfer feed.

Across fourteen years of covering football, from local radio stations to matches in England, I have learned one thing: people measure a football nation by its stars, but it actually lives on the number of players good enough to step into a position in turn. Vietnamese football's big-tournament season — with V.League 1, World Cup qualifiers, and successive AFF Cup and SEA Games campaigns — is putting that question on the operating table. When the calendar compresses, when a team must play three matches in eight days, squad depth stops being theory. It becomes survival.

Context: When the calendar compresses emotion

Vietnamese football is at a strange moment. At club level, V.League 1 is increasingly competitive tactically, but the gap between the leading group and the relegation group sits mainly in depth, not in the quality of eleven starting names. At national-team level, coach Kim Sang-sik must rotate across FIFA Days, friendlies, and qualifiers, while most of his core players have passed twenty-seven or twenty-eight.

What catches my attention is not the wins. It is how teams change after the 70th minute. In many V.League matches I have watched live, the gap in running intensity between the first and second half of the same team can reach twenty percent. That is not a mentality problem. It is a squad-structure problem.

The five-substitution rule, widely adopted after the pandemic, is in theory a gift to leagues with deep squads. But it also turns the final twenty minutes into a war of attrition. If you have five substitutes good enough to enter without collapsing the system, you win. If you have only three, the remaining two slots are there to absorb injuries — and when that happens, the match belongs to the opponent. The rhythm of a season is not in the goals, but in every repeated Saturday.

Analysis: What squad depth is actually measured by

I began keeping notes differently. Instead of counting goals, I counted how many players each team was willing to bring on at the 65th minute of a decisive match. That number, to me, is more honest than any results table.

At a well-built club, a substitute slot is part of the system, not a reaction to it. The player coming on knows exactly which gap to run into, whom to cover, how to change the tempo. At a patched-together club, the substitute enters to plug a hole, and the whole team drops ten metres to protect him. Twenty metres of pitch, in football, is an entire season.

I remember the colour of the grass that day before I remember the score. The session I mentioned at the start was one of seven I observed over three months. What I recorded was not the beautiful plays. It was how the coaching staff split the groups. One session at the PVF Academy, one at HAGL, one at the academies of Viettel or Hanoi FC — each has a different philosophy, but the common thread is this: they teach young players to play within a system before teaching them to shine. The uncomfortable truth is that Vietnam's best academies are doing the work that professional clubs should be doing: developing players not to sell, but to use.

Here a paradox of talent flow appears. A young player developed from age eleven, by age nineteen, is often sold or loaned out precisely when he is closest to being ready — because the club needs money, or because the coach needs an immediate result. The result is a football nation that keeps producing good players at twenty, then loses track of them by twenty-three. That is a form of talent leakage no table records.

I once had seven video-call interviews with young players during the period when football was suspended. What I heard was not fear of losing form. It was fear of being forgotten. A twenty-year-old told me the scariest thing was not injury, but not knowing where he belonged once his loan ended. An empty stadium is a heartbeat learning to beat again. So is a player without a club.

The contrarian angle: The problem is not talent

What international media and outside fans often get wrong about Vietnamese football is the belief that the problem is talent. They look at a few stars — Nguyen Quang Hai, Nguyen Tien Linh, Do Hung Dung — and conclude that this football nation depends on individuals. That conclusion reads cause and effect backwards.

Vietnamese football does not lack talent. It lacks a mechanism to keep talent long enough for players to grow up together. The stars the world sees are the tip of an iceberg built over twenty years. The submerged part is hundreds of unnamed young players who should have formed the cushion for the next generation — but vanished at an age when, in developed football nations, they would still be apprentices.

This is where the transfer feed deceives us. A blockbuster deal generates headlines, but it does not generate squad depth. Squad depth is generated by small, steady, multi-season signings. The exclusive story is only the tip; the submerged part is the midnight calls between a sporting director and a youth coach, debating whether a nineteen-year-old is ready for fifteen minutes in the V.League.

I once spent seventy-two hours verifying a transfer story, calling three different sources, just to be sure that what I was about to write was true. That process taught me one thing about Vietnamese football: the most important decisions are almost never announced. They happen in closed meetings, in closed training sessions, in messages no one saves. And that is precisely why a football nation can look strong on the feed yet remain fragile on the pitch.

Another contrarian angle concerns the relationship between development and business. When clubs are forced to sustain themselves, they tend to sell young assets to balance the books. That makes sense in the short term financially, but destroys squad depth in the long term. A player leaving on a free transfers no fee, but leaves a gap the academy needs five years to fill. In Vietnamese football, those gaps are often never filled — they are simply replaced by a newer, younger, cheaper name, and a more vulnerable one.

Signals to watch

There are three signals I will watch for the rest of the season. First, the minutes played by players under twenty-two in V.League 1. If that number rises steadily week by week, it signals that clubs are beginning to trust their own squads rather than buying short-term solutions. Second, the number of loanees who return and are actually used, rather than being pushed out again. Third, how the national team rotates during its camps — whether Kim Sang-sik dares to give players aged twenty-one or twenty-two a chance in non-decisive matches.

To write a true story, I have to stand where no one stands. I have stood at the edge of a training pitch, in the chill of a late morning, watching young players run their final laps with no one clapping. Vietnamese football will not be decided in the big matches. It will be decided in the training sessions no one films. The press tower is the highest place to see from, but not the closest place to understand.

A thought to carry away

If I had to choose one thing to follow this big-tournament season, I would not follow the table. I would follow the 70th minute. Who is still running? Who still trusts their system? Who can make a substitution without trembling? Vietnamese football has proven it can produce exceptional individuals. The question of the next decade is whether it can produce teams deep enough not to depend on any individual. That is not a question of talent. It is a question of patience — and of whether we have the courage to invest in the afternoons no one sees.
