U23 Vietnam reach Asiad 2026 quarterfinals: Three identical matches, one recurring problem

Three group matches, three almost identical scripts. U23 Vietnam controlled the ball, created chances, missed, then conceded from situations too easily. Former international Nguyen Tuan Phong does not call it bad luck. He says it directly: three identical matches, and the team missed too many chances. I read this assessment right after Group C closed, and I saw something more important than the quarterfinal ticket: a team can advance on results, but cannot go far with a system that keeps eroding itself. U23 Vietnam lost 0-2 to Uzbekistan in the final Group C match, but still qualified for the Asiad 2026 quarterfinals thanks to other results in the group. Reaching the last eight is a significant achievement, especially for a young team in transition after the 2026 AFC U23 Asian Cup. But the manner of progression leaves no room for comfort. On Tuoi Tre, Nguyen Tuan Phong delivered a structural diagnosis, not a simple emotional reaction. "Three identical matches" is the phrase he uses to describe a recurring set of problems: good control, wasted chances, defensive errors. To me, this is a systemic signal. A team is not a collection of numbers; it is a living system breathing through every pass. When a system repeats the same kind of failure in three consecutive matches, it cannot be explained away by luck. Tuan Phong sees a team that keeps the ball well but fails to convert. At the same time, the defence conceded two goals "too easily" against Uzbekistan. These two issues seem separate, but they are connected by the same thread: the lack of a solid defensive structure from distance. Tactically, U23 Vietnam played with a back three, perhaps 3-5-2 or 3-4-3. Two wing-backs pushed high to provide width, but when both advanced at the same time, the space behind them became an area for opponents to exploit. Tuan Phong pointed out that Le Dinh Long Vu was heavily exploited on the left flank in the first half. Only when Phi Hoang came on did the situation improve. This is an important detail. It shows the coaching staff can read the game and correct, but correction only comes after punishment. In the group stage, that may be acceptable. In the quarterfinals, one loose half can end the tournament. Tuan Phong also mentioned the absence of a holding midfielder, a destroyer in front of the back three. In a back-three system with attacking wing-backs, the defensive midfielder is almost the most important role. He does not need to be outstanding in attack, but he must read the second ball, close the space in front of the box, and support the centre-backs on transitions. Tuan Phong called it the "Thai Son type". When both Xuan Bac and Nguyen Thai Quoc Cuong lean toward attack, Vietnam's midfield has no shield. The centre-backs are constantly left in one-on-one situations with opposition forwards. It is not that they are poor; the system puts them in impossible positions. Personnel shortages make the problem worse. Hieu Minh and Nhat Minh, the first-choice centre-backs, were absent in the decisive match. The defence had to use newer centre-backs such as Duc Anh, Le Nguyen Hoang and Pham Ly Duc. These three have not yet built smooth coordination. The centre-backs do not cover each other on long balls over the top. This creates a paradox: the team has a lot of possession, but every time they lose the ball, the goal is directly threatened. Possession becomes a screen hiding a fragile defence. The attacking story also needs a fresh look. "Missing many chances" in three straight matches is not simply a finishing problem. If one player misses a one-on-one, that is an individual error. If the whole team misses chances in three matches under the same script, the problem may lie in the quality of chances created. Many shots are taken from poor positions, or rushed under mental pressure. I used to believe in absolute numbers, until the World Cup taught me that emotion is also a variable. In the youth game, that variable is even bigger, because the players lack experience to stay calm in front of goal. The more they miss, the more they rush; the more they rush, the more they miss. That is a loop that basic shot counts cannot fully show. The absence of Dinh Bac makes the problem even clearer. Dinh Bac is the type of player who can create a moment of difference with an individual action. Without such a player, the team must rely on collective patterns to break down a packed defence. But a collective cannot create enough difference if there is no holding midfielder to balance the team. Losing the creative reference point on top, and losing the defensive shield underneath, U23 Vietnam become a team with the ball but without the cutting edge. It must be said: Tuan Phong's assessment contains no xG, PPDA or passing statistics. I cannot quantify the quality of U23 Vietnam's chances in the past three matches. But the absence of data is itself information. In a tournament where Asia's leading teams use data as instinct, the fact that an expert has to rely on visual impressions to describe a repeated pattern shows a gap in analytical capacity, not just in player quality. Data does not provide answers; it points to the questions we are brave enough to ask. The question here is: why does a team that controls the ball so well fail to create clear chances? Why is the defence constantly exploited in the same area? If those questions are not answered, the quarterfinal will not forgive them. The counter-intuitive point in this story is that U23 Vietnam's biggest problem may not be the forwards missing chances, but a midfield with no defensive presence. When both central midfielders are attack-minded, the space between midfield and defence becomes a comfortable zone for opponents to receive the ball, turn, and play a decisive pass. The centre-backs are pulled out of position, and "easy" goals appear. If we only blame the centre-backs for not covering each other, we are treating the symptom. The cause is the absence of a player doing the dirty work in front of the back three. In the quarterfinal, against opponents with better individual quality, an invisible holding midfielder will become a disaster. Tuan Phong compared this squad with the 2026 AFC U23 Asian Cup generation, saying the team is "weaker than itself". This is difficult to hear, but necessary. At the 2026 AFC U23 Asian Cup, U23 Vietnam beat South Korea on penalties in the third-place match. That achievement set a very high benchmark. Compared with that milestone, this Asiad squad has lost key pillars, especially in defence and midfield. We cannot demand a team missing personnel in the two most important lines to perform like the older generation. But we should not use that excuse to justify a system that keeps repeating mistakes. Uzbekistan at Asiad 2026 was described by Nguyen Tuan Phong as a class youth team. This is not a courtesy. It is a confirmation of the gap. U23 Vietnam could keep the ball quite often against Uzbekistan, but could not suffocate them. When the opponent has a more mobile midfield and better physicality, possession becomes a luxury that offers no defensive value. I have seen many Southeast Asian teams fall into this trap: they hypnotise themselves with possession stats, while the opponent needs only three passes to reach the goal. The lesson from U23 Vietnam in Group C should be read that way. The opponent context makes the problem urgent. Tuan Phong stressed that teams with a strong midfield and good physicality will cause many difficulties. This is exactly the profile of the Asian teams U23 Vietnam may face in the quarterfinals. If they meet South Korea or Saudi Arabia, U23 Vietnam will likely lose control of midfield. In that case, the reasonable choice is not to keep the ball, but to accept a low block and rely on quick transitions. But quick transitions require defensive security. The defence is currently the weakest area. This is the vicious cycle the coaching staff must break. One of the few positive signals is the ability to adjust during the match. Bringing on Phi Hoang improved the left flank, according to Tuan Phong. That shows head coach Dinh Hong Vinh is not rigid. He can identify bottlenecks and react. But in the knockout round, reaction often comes too late. A team needs to be proactive from the start, especially against superior opponents. Waiting until conceding to make changes is a risky strategy. Regarding personnel, the biggest question is the return of Hieu Minh and Nhat Minh. If one of those centre-backs recovers in time for the quarterfinal, the defensive risk drops significantly. If not, Dinh Hong Vinh must consider using a real defensive midfielder, even if it reduces attacking power. A knockout match is not the place for experiments. The team needs one clear plan, even if it is not beautiful. I have seen many youth teams win in the group stage because of emotion, then stop in the knockout stage because of a lack of system. U23 Vietnam is not really a weak team. They have technique, confidence on the ball, and a coach who knows how to correct. But top-level football does not reward soulless control. It rewards teams that learn from mistakes, repeat what works, and eliminate what does not. Three group matches have shown the same mistakes repeated. The quarterfinal is the time to prove they can learn from themselves. The final question is not who U23 Vietnam will face. The final question is whether this team dares to abandon the habit of playing pretty football to play pragmatic football. If the answer is yes, the quarterfinal still offers a chance. If the answer is no, the Asiad 2026 journey will end with a familiar script: possession, missed chances, and a conceded goal. I hope they choose something different, because football always needs change drawn from repeated lessons.
