Three Identical Matches: U23 Vietnam Advance at Asian Games 2026 but Structural Flaws Remain

On the scoreboard, U23 Vietnam still secured a place in the quarterfinals of the 2026 Asian Games. After the final match of Group C, the squad under coach Dinh Hong Vinh suffered a 0-2 defeat to Uzbekistan, yet still advanced alongside that very opponent. Looking at the points column, that is a result good enough to be called a success.

But after the final whistle, what lingered in the technical area was not the ticket, but a sense of familiarity that was hard to shake off. Former international Nguyen Tuan Phong called it "three identical matches." Three matches, three times U23 Vietnam controlled the ball well, created chances, then squandered them. Three matches, three times the defense allowed the opponent to score far too easily. For someone who once stood inside the penalty box and paid the price for every ball, a pattern repeating three times is no longer bad luck.

Reviewing footage is not a sign of distrust, but a way of respecting the truth. When rewinding the three group-stage matches, the concern is not in any single moment, but in a structure repeated identically. U23 Vietnam are committing a systemic error, not a timing error.

Context: a ticket not entirely self-determined

To judge fairly, the context must be set properly. Group C concluded with the two qualification spots going to U23 Vietnam and Uzbekistan. Results in the other fixtures — where Kuwait and the Philippines failed to produce a shock — opened the path for Dinh Hong Vinh's men. Put plainly, the quarterfinal ticket partly came from others' results, not only from their own effort.

Uzbekistan is placed by pundits in the "class" bracket of continental youth football. The way people speak of them already shows the gap in level. The 0-2 defeat is therefore easily framed as "losing to a stronger team" — a way of calming public opinion. But when that defeat repeats the same script as previous matches, the story no longer lies with the opponent.

Nguyen Tuan Phong did not comment on emotion. He pointed to three problems at once: a makeshift defense, the absence of a true defensive midfielder, and a poor-finishing attack. All three were present in the Uzbekistan match. That is why I chose to dissect this problem from its structural root, rather than list names and stop there.

The back-three system and the space behind the wing-backs

U23 Vietnam operated a three-center-back system with two advanced wing-backs. This is a modern structure, common in Asian youth football. The problem lies in execution, not in the idea. Three center-backs are tasked with covering each other; when one pushes up, the adjacent one must fill in. Against Uzbekistan, that covering almost never appeared.

The left flank of Le Dinh Long Vu was heavily exploited in the first half. This is the classic weakness of a back-three: the space behind an advanced wing-back. Uzbekistan drilled into it with balls channeled wide, forcing the left-sided center-back to leave his position, and as the defense became disjointed, space opened in front of the box. In the second half, the introduction of Phi Hoang improved the situation. This is a positive signal — the coaching staff can read the game. But it also shows the response was merely reactive: only after the gap was painfully exposed did adjustments come.

What is notable is that across all three matches, this pattern barely changed. The ball was controlled, the game was at times superior, but the moment the opponent accelerated down the flanks, the defense was exposed. Possession without an accompanying defensive structure is merely false safety. When an opponent knows where and how you will lose the ball, they only need to repeat one routine.

It must be added that a back-three is not inherently wrong. Many big teams use it and defend very solidly. The fault lies in this: these three center-backs were not yet trained to play as a block. They stood close geometrically, but were not connected in responsibility. A solid defense is not three good individuals, but three people who understand each other so well they need not look to know where a teammate will retreat.

Two first-choice center-backs missing and the personnel problem

Part of the cause lay beyond the coaching staff's control. The two most highly regarded center-backs, Hieu Minh and Nhat Minh, were both unavailable. The central defensive position was therefore handed to a makeshift trio: Pham Ly Duc alongside two newcomers, Duc Anh and Le Nguyen Hoang. Understanding among the three could not arrive within a few matches.

Putting together a brand-new defense at a continental tournament is no small matter. Center-backs do not play on instinct like forwards; they play on positional discipline and mutual understanding. When three people have not played alongside each other long enough, the gaps between them are far larger than those between center-backs already familiar with one another. The opponent needs only one through-ball or one well-timed aerial ball to break through.

Had only two center-backs been missing while the midfield remained solid, the problem would be different. But U23 Vietnam exposed both weaknesses at once: a new defense and a midfield lacking a shield. This overlap of risk made the two goals conceded against Uzbekistan look more inevitable than accidental.

This is the point viewers often overlook. They see one clumsy individual moment and conclude that this center-back is poor. But the problem lies not with any individual. When the whole system is under-trained, the one who errs is usually the one carrying the most, not the least capable.

Missing a genuine defensive midfielder

In a back-three system, the most important role is not the center-back, but the defensive midfielder sitting right in front of them. This player is the shield: when the wing-back pushes up, he retreats to block the space; when a center-back is pulled wide, he covers inside. Without him, the three center-backs stand bare against counter-attacks.

U23 Vietnam has no purely defensive midfielder of that kind. The two central midfielders used — Xuan Bac and Nguyen Thai Quoc Cuong — both lean toward attack. Both can hold and pass the ball, but neither performs the windbreak duty. As a result, when the team loses the ball in midfield, the defense faces the opponent directly with no cushion in front.

Nguyen Tuan Phong mentioned the "Thai Son type" — a player who does one job: clear the ball, block the ball, hold position. That absence is not peculiar to the Uzbekistan match. It is a long-running personnel issue, and worse, it appears to have no answer within the current generation. A midfield full of ball-carriers but no ball-winner is a structure that cancels itself out.

This leads to a double consequence. With no ball-recoverer, the attacking midfielders must drop deeper to support the defense, and as they drop, the attack loses its supply line. The team falls into a vicious circle: the attack weakens because it must mind the defense, the defense weakens because it lacks a shield. This is the kind of structural contradiction no individual can fix through effort alone.

Wasted attack and the story of "three identical matches"

If only the defense were poor, U23 Vietnam could still compensate with attack. But the attack was the most disappointing area. In all three matches, the team created chances and squandered them. In all three, the conversion rate was low. The "three identical matches" Tuan Phong referred to concerns not only how goals were conceded, but how chances were wasted.

I have no data to quantify chance quality. There is no xG, no shot count, no expected-goals metric in the accessible data. But one thing can be said without numbers: when a team misses in the same way across three matches, the problem usually lies not in finishing, but in the quality of the chances themselves. Many chances came from difficult positions, narrow angles, or under close marking. Missing those is not necessarily the striker's fault.

The absence of Dinh Bac makes the picture even clearer. He is the type of player who can create chances for himself — one who solves deadlock with an individual moment. Without him, U23 Vietnam's attack depends entirely on collective play. When the collective runs smoothly, it is fine, but when a moment of unlocking is needed, no one steps up to take responsibility.

One more thing must be said about individual dependence. A young, healthy team is often built around a few exceptional individuals. When those individuals are absent, the whole system wobbles. That is the mark of a team not yet mature in structure. A great team must function even without its stars. The current U23 Vietnam has not reached that threshold.

The counter-intuitive view: Tuan Phong is right, and he is also doing something else

At this point, a question few raise must be asked. Is Nguyen Tuan Phong's assessment entirely fair to coach Dinh Hong Vinh?

He pointed out many of the team's flaws, but also created a notable comparison frame: "the current generation is weaker than itself" — implying a decline compared to the Kim Sang Sik era. This is a weighty judgment. It criticizes not just one match, but the entire team-building process.

But one point must be separated out. When Tuan Phong raised personnel problems — missing center-backs, missing defensive midfielder — he was in fact pointing to limitations of the generation itself, not necessarily to managerial ability. Dinh Hong Vinh did not choose to have two center-backs absent, nor did he conjure a defensive midfielder from thin air. His responsibility is to organize the team around what he has.

In that respect, he did one important thing: he read the game and corrected it in the second half. The Phi Hoang substitution improving the left flank shows the coaching staff is not helpless. In knockout football, the ability to read a match and adjust is a valuable asset. A match may pause, but the responsibility of the man in charge does not.

So why did Tuan Phong publicly lower expectations so much? There is a subtler explanation than mere criticism: he is managing expectations. Ahead of a harsh knockout round, where the risk of meeting South Korea or Saudi Arabia is real, speaking beforehand about limitations helps soften the shock if the team is eliminated. This is a familiar move by pundits: setting the script in advance so public opinion is not caught off guard.

This does not diminish the value of his analysis. But it issues a warning: do not read "three identical matches" as an indictment, but as a reminder. The sample is only three matches — small for concluding anything about an entire generation. A mistake is a footnote; only silence is a verdict.

There is one more point to see fairly. Public pressure on Dinh Hong Vinh is currently at a medium level, not a crisis. There are no jeers, no protests, no wave demanding dismissal. This is a phase of controlled criticism, not an explosion. For a coach in a transitional period, keeping that calm is already a small success.

The root of the problem: a football nation producing more forwards than defenders

The most worrying thing is not one match. It is that all three problems — a thin defense, a midfield without a shield, an attack dependent on individuals — point to one root: the current generation is trained lopsidedly.

Vietnam produces better attacking players than defensive ones. Dinh Bac is the clearest example. But in the center-back and defensive-midfield positions, the youth team has no equivalent names. When both first-choice center-backs are absent, the team has no worthy replacement. When a defensive midfielder is needed, the team finds no one. This is a problem of an entire training system, not of one tournament.

Broadly, this is a familiar pattern in Southeast Asian football. Football nations in the region often export attacking players to Japan, South Korea and Europe, while defensive positions are less sought after and less invested in. The result is youth teams with creative attacks but fragile defenses. U23 Vietnam sits within that pattern.

This observation is not meant to be pessimistic. It is meant to show that the problem cannot be solved in one tournament. To have a genuine defensive midfielder, there must be a generation trained for that role from childhood. To have depth in center-backs, academies must invest in less glamorous positions. That is the work of many years, not of one knockout round.

Looking to the quarterfinals: what must change

Entering the quarterfinals, U23 Vietnam faces a crossroads that could shape the entire campaign. Three priorities must be laid on the table first.

The first priority: the defense must be strengthened structurally, not just personnel-wise. If Hieu Minh or Nhat Minh returns, the understanding will be better. If not, the team needs a deep-lying midfielder to cover — even accepting a lower block to reduce the space behind the wing-backs. Possession cannot substitute for defensive organization.

The second priority: the attack must create higher-quality chances, not just more of them. Against organized defenses, long-range shots rarely score. It needs plays that break the last line, one-on-one situations near the box. Without Dinh Bac, this responsibility must be shared more evenly.

The third priority, and the most important: the team must accept the reality of its standing. U23 Vietnam sits in the tier of "competitive but below the strong teams." That is not a confession of weakness, but a basis for choosing how to play. Playing open against a physical, strong-midfield team is suicide. A low block with fast transitions is the more viable path.

There is a historical benchmark worth remembering: at the AFC U23 Asian Cup 2026, this generation beat South Korea on penalties in the third-place match. That proves that on the right day, the team can overcome a stronger opponent. But the right day does not come by itself; it comes from the right adjustments.

In the quarterfinals, the question is no longer whether U23 Vietnam has talent. The question is: does the team have the courage to abandon the habit of prolonged possession to play in line with the players it actually has? The answer will decide the semifinal ticket — and more than that, will decide how a generation of players learns that control is not the goal, but only the means.
