V-League: A Suspension Cannot Fix a Habit Taught at Under-11 Level

In the last three V-League rounds, I counted four two-footed challenges that produced red cards. One of them led to a four-match suspension for Văn Hậu after a challenge on Doãn Ngọc Tân. I sat in Seoul and replayed the footage at two in the morning Korean time, slowing down every incident frame by frame. What made me stop was the location of those challenges: most happened in midfield, more than forty metres from the opponent's goal, in situations where the offending player's team was actually in possession. Nobody launches a two-footed lunge in midfield, far from goal, if the only motive is winning the ball. A different motive lives somewhere else, and it was formed long before these players signed their first professional contract.

Vietnamese football is treating the consequences of a problem manufactured at the bottom, using tools that only work at the top.

This week, a European expert gave an interview to Dân trí and put his finger on the right spot: the V-League needs to build football culture from the youth level. He talked about teaching tackling technique, managing duels, and treating respect for opponents as a teachable skill. He also talked about how youth coaches in Vietnam rely too heavily on playing experience and street-football experience rather than certified, properly trained qualifications.

I have followed the V-League from South Korea for more than a decade. Not by reading results, but by rewinding match footage round by round and logging notes in a separate file. That file is called "V-League — contact log", and it thickens steadily every season. What I record is not the card count but the incident behind the card: who initiated, who was passive, where the ball was, what the scoreline was.

This season's picture has one clear feature. Violent incidents cluster in the early phase, when starting places are not yet settled. The expert in the interview says this outright: players are competing for starting spots, so they challenge harder than normal. That is a valuable observation, because it shifts the story from "player morality" to "incentive structure".

But it does not go far enough.

Matches are played in heavy rain on poor pitches. The ball travels faster, bounces unpredictably, players slip more, and collisions therefore increase. This variable is mentioned by the expert and I agree with it. But pitch quality raises the probability of a collision; it does not create the intent to collide. The two incidents in which Tấn Sinh and Văn Sơn lunged at the same player, Đình Bắc, are not the product of a bad pitch. A bad pitch does not choose its target.

So who should be dealt with?

Here I need to state clearly how I work, because it governs the rest of this piece. Every contract I have ever dissected had three numbers: the published number, the real number, and the number the industry wants others to believe. I once misread a contract live on air, so now I have to cross-check three sources before I speak. That habit applies to the disciplinary story too; only the unit of measurement changes.

With Văn Hậu's four-match ban, the three numbers look like this. The published number is four matches, clean and easy to print. The real number is the actual minutes the club loses, plus the points dropped in that window, plus the transfer value adjustment after a player has been stamped "dangerous tackler". The third number — the one people want you to believe — is a story about discipline tightening and working.

I do not have the club's internal data to say what the real number is. But I have an indirect test, and it needs no internal data.

The expert offers a very clean test: if dangerous incidents keep recurring despite disciplinary measures, one must question the effectiveness of current sanctions. He also defines the purpose of punishment as having two parts — punishment and prevention. Combined, he has just supplied an evaluation metric: the recurrence rate. Not the length of the ban, but the recurrence rate.

This is where I want to linger longer than other commentaries do.

World football measures the quality of a disciplinary system by its recurrence rate. A league that raises bans from two matches to four while the recurrence rate stays flat is escalating form, not changing behaviour. A league that keeps ban lengths the same but applies them consistently, regardless of reputation, while the recurrence rate falls, has found the right lever.

A sanction only has value when its consistency exceeds the fame of the person being punished.

The expert stresses the need for penalties that are "sufficiently deterrent" and "stricter and more consistent". The word "consistent" is the most important word in the whole interview, and it says more than the word "stricter". When an outside expert has to press on consistency, the implication is usually that the current system is being run case by case rather than against a fixed scale. I have no quantitative proof of that implication. I log it at medium confidence.

The same test, applied to economics, produces a different result that few sports-page readers notice. The cost of discipline does not sit on the balance sheet. It sits elsewhere: a player suspended for four matches reduces squad depth, forces rotation, raises the load on the remaining key players, and thereby increases the injury risk of the very men who were not punished. This loop never appears in any financial report, but it is real, and it compounds over a season.

In South Korea, I once watched a K-League club build its season plan on one simple assumption: each season, its squad would lose roughly X minutes to suspensions. That X was drawn from the club's own historical data and fed into its physical load model. I raise it not to compare who is better, but to point out that in leagues run on models, discipline is a forecastable variable, not a random outburst.

And this is where the interview's content carries real weight.

The rest of the argument revolves around one idea: on-field violence is the product of an incomplete football education, not of a handful of bad individuals. The offender learned to tackle somewhere, in a training session at eleven or twelve years old, under an adult's guidance. If that adult did not teach, or worse, taught wrongly, then by twenty-two the behaviour has become a conditioned reflex. The expert says it plainly: in some coaching environments, young players are encouraged to play aggressively or to intimidate opponents. He also says these behaviours form early and harden over time, making correction at professional level a low-yield operation.

That is a fairly testable proposition, and I want to test it along a different route from the one domestic commentators usually take.

If the problem lies with the teacher, the next question is: who teaches the teacher? The expert answers indirectly when he says too many youth coaches in Vietnam rely mainly on playing experience or street-football experience. That is a statement about human capital structure, and it is more serious than any suspension. A football nation can naturalise players, can hire foreign technical directors, can import curricula. That football nation cannot import a generation of youth coaches in a single season.

In South Korea, the coaching licence system is tiered, and to lead a youth team at a high level you must pass through promotion stages with minimum time requirements. I am not saying that system is perfect. I am saying it creates an entry barrier, and an entry barrier creates a minimum quality floor. In Vietnam, when a retired player can walk straight into a youth coaching role on the strength of his playing reputation alone, the quality floor depends on that individual's personal qualities. Personal qualities are a random variable. No system should operate on a random variable at national scale.

And this is the link that commentaries on V-League violence usually skip.

The expert says young players always look up to senior professionals as role models. If at the top level excessive physicality is accepted and sometimes celebrated, then below it becomes the norm. He calls this a role-model problem, and it flows downward: from the V-League to the first division, to academies, to grassroots football. Which means V-League disciplinary policy, designed to protect professional players, is in fact a youth-development policy. That is one of the most important sentences in the interview, and I think it has not been mined deeply enough.

If someone asks me why a four-match ban in the V-League matters more than it appears, I would answer with this chain: punishment at the top level sets a reference price. That reference price flows downward. At the lower level it becomes a habit. That habit returns to the V-League in the form of a twenty-three-year-old with an already hardened reflex. The loop closes, and each season adds another layer to it.

Seen from Seoul, what stands out is that Korean football went through a similar phase, at a different physical scale. In the 1990s and early 2000s, the K-League was criticised for a hard playing style, and it took nearly a decade for academies to change their value system. I remember reading the technical minutes of one academy, where the discussion was not about banning two-footed tackles but about re-teaching tackling technique from a standing position. They spent an entire season teaching one apparently basic movement. That is the level of patience a football nation must accept once it decides to fix the root.

Mapped onto Vietnamese football, the timeframe is not very different. A programme to retrain the youth coaching workforce, with certification, minimum hours and periodic assessment, will take at least five to seven seasons to produce a different generation. No amount of money shortens that number. That is the price of letting the coaching system lag the competition system for too long.

Now the part I think the league organiser and the federation should read most carefully.

In the interview, responsibility is placed on both the Vietnam Football Federation and the league organising company. The expert bundles both into one sentence about shared responsibility. That framing is correct in principle, but the operational risk sits precisely in the word "shared". When two institutions share responsibility and there is no clear division of authority, the usual outcome is that both wait for each other. I have seen this model in many Asian leagues, and it always ends the same way: a workshop, a press release, and no structural change.

A clear division of authority, by contrast, produces fast results. Someone must be ultimately accountable for the sanction scale. Someone must be ultimately accountable for the youth coach certification standard. If those two questions have two different answers but sit in the same meeting room, the problem will survive multiple leadership terms.

On timing, there is one detail I want to log with a concrete figure so readers can verify it themselves. The early phase of a season is when competition for starting places peaks, and it is also when card counts rise. That is a cyclical phenomenon, not an anomaly. What matters sits elsewhere: if foul intensity declines as line-ups settle, the motive is positional competition. If foul intensity holds all season, the motive is culture. These two causes require entirely different interventions, and a football nation that cannot tell them apart will spend its money in the wrong place.

This is the counter-intuitive point I want to press.

The popular reading right now is that the V-League is being attacked from outside by a handful of rogue players. That reading turns the solution into crackdown, and crackdown is fast, cheap and press-friendly. But in the two incidents aimed at Đình Bắc, what was displayed was not poor tackling technique. It was target selection. Tấn Sinh and Văn Sơn are two different players, in two different incidents, both aiming at one opponent. Target selection requires awareness of the target, and awareness of the target is hard to reduce to "taught tackling badly". It is closer to an unwritten convention in the dressing room: this player needs to be taught a lesson.

The educational framework the expert offers handles the movement. It does not yet handle the convention. To handle the convention you need a different mechanism: pattern-based investigation rather than single-incident investigation. A disciplinary body must be able to see one player targeted twice in three rounds by two different opponents and treat that as one data point, not two unrelated accidents. Without that mechanism, every sanction is processed as an isolated slice.

The second blind spot is subtler, and it belongs to the article itself.

The interviewee is an unnamed European expert. No name, no affiliation, no cited credential. He has also answered this outlet several times and always pressed the same message. On one hand, the repetition shows a stable and deliberate message. On the other, the fact that a football nation must borrow the authority of an anonymous foreigner to legitimise an internal view is itself a data point about that football nation. Insiders are usually silent; outsiders are usually certain. In Vietnam, a named youth coach saying the same sentence would face a very different professional cost from an unnamed European expert. That gap in the cost of speaking is itself the measure of a football nation's technical freedom.

At fifty-six, I only trust the clause. There is no clause in an anonymous interview. Which means the value of this article sits in its diagnostic frame, not in its evidence. I am willing to use that frame for further analysis, and I am not willing to use it as a substitute for data.

So what is actually shifting?

Three layers are moving at once, at different speeds. The disciplinary layer moves fastest, because a sanction can be issued within a week. The institutional layer moves more slowly, because dividing authority between the federation and the league organiser takes time. The layer that trains the teachers moves slowest of all, because it depends on a generation.

Most fans only see the first layer, where red cards and suspensions live. The decisions that will genuinely shape the V-League's quality over the next decade sit in the third layer, where there is nothing to print this week.

There is one thing I have always kept from working with academies: the quality of an academy is not measured by how many players it sends to the first team, but by how many bad behaviours it removed before those players signed professional contracts. That is a metric nobody publishes, because it looks bad on a trophy board. But it is the only metric that accurately reflects teaching capability.

For the V-League, I think the next round will give an early answer. If dangerous challenges decline, we are dealing with positional-competition incentives, and everything is far simpler than the current commentary suggests. If they continue, and continue to target the same victims, then what needs fixing sits somewhere no suspension can reach: the youth coach certification curriculum, and a dressing-room convention that has never been named out loud.

I will keep logging the "contact log". And next time, I will add a new column: the gap between the number of cards issued and the number of behaviours corrected. That is the number the league organiser should calculate before announcing any new sanction scale.
