Vietnam U23 at Asian Games 2026: 16 Returning Names and the Real Test Kim Sang Sik Needs

There is a sequence of numbers I have marked in red in my notebook for two weeks now, since the day the Vietnam Football Federation announced its target for the U23 team at the 2026 Asian Games: sixteen out of twenty-three.

Sixteen of the twenty-three players in Vietnam's U23 squad for Asia's largest multi-sport event had already been part of the July training camp. That figure never made a headline in the domestic press, but to me it matters more than the quarter-final ticket the federation placed on the table.

The night before the team departed, I sat down with game footage of Vietnam U23 facing regional opposition at the AFC U23 Championship earlier this year. I rewound and replayed the midfield transition sequences. Midway through the second half, as the opponent pushed their line higher, there was one passage of play in which three U23 players moved as if they had played together for an entire season. They had, in fact, played together. Not a full season, but long enough for the body to remember.

That is why I am not truly preoccupied with whether Vietnam U23 can reach the Asian Games quarter-finals. What deserves more attention lies elsewhere: what kind of yardstick is being used to measure these twenty-three individuals, and who is holding it.

When the VFF assigned a quarter-final target for the 2026 Asian Games, the first reaction of most fans was relief. A moderate milestone, neither too ambitious nor too low. But relief is the most dangerous feeling in elite sport, because it lulls both the people setting the target and the people carrying it out.

Look at the list of twenty-three names. Most of them have already played one or two seasons in the V-League, alongside experience at youth level and, most recently, the AFC U23 Championship. In other words, this is not a naive collective stepping onto the continental stage with trembling legs. This is a team that has tasted physical confrontation.

The seven different faces compared with the last training camp, including Ly Duc, Quang Kiet, Pham Minh Phuc, Le Phat and Ngoc My, are not unfamiliar names. They are players who have appeared within the system, they simply have not yet had the chance to share a single frame with the rest of the group. The personnel differences here are additive, not a tear-down and rebuild.

Vietnam U23 sharing a group with Uzbekistan, Kuwait and the Philippines is certainly not comfortable. Uzbekistan is the most formidable opponent, a youth football program that is methodically funded and has a habit of making life difficult for Southeast Asian football. But the chance to compete for the two leading positions remains wide open, because Kuwait and the Philippines are not insurmountable barriers.

If they make good use of the two matches against Kuwait and the Philippines, coach Dinh Hong Vinh's students can absolutely secure a place in the quarter-finals. They could even think further and replicate the achievements of their predecessors, meaning a place in the semi-finals or even a medal.

But that is the part of the story the media has told too many times. I want to pull attention toward another layer of data, one few people bother to pick up.

Sixteen out of twenty-three is not a figure of stability. It is the figure of a controlled experiment.

The period of working together from the July camp creates a certain stability, from the way the team operates to the mutual understanding between positions. But in modern football, understanding is not measured by the number of days spent sharing meals. It is measured by the number of successful combinations under real-time pressure.

I re-watched footage of this U23 generation's most recent matches and counted manually. In the first thirty minutes of each match, Vietnam U23's transitions from defence to attack typically take two to three seconds to establish a direction. Against opponents of a similar level, that is fine. Against continental-calibre opponents, three seconds is more than enough time for the opposing back line to drop and organise.

That is why I view the sixteen returning slots not as a gift but as a conditional investment. They were given time because they had proven their capacity to withstand pressure within the system, not because their names appear on a youth achievement board.

Players create moments, systems create players. A collective of sixteen names who have campaigned together holds an advantage in collective muscle memory, but that advantage only pays off if the coaching staff dares to keep them on the pitch at the right moment and in the right scenario.

There is one detail here that I consider pivotal. Coach Kim Sang Sik, together with the VFF, changed the plan, shifting from an intention to use a U21 contingent to an almost full-strength squad. This decision carries meaning far beyond the boundary of a single tournament.

More concretely, coach Kim Sang Sik has surely made calculations for the future of the Vietnam national team after the 2027 Asian Cup. The current U23 players are part of that plan. And to have a chance, they must place themselves within the Korean strategist's field of vision through performances against opponents of sufficient quality at this Asian Games.

The Asian Games is therefore no longer purely a tournament. It is a continental-scale laboratory, where samples are placed side by side under the same weather, the same opponents, the same performance pressure.

This is where I want to interrogate myself before interrogating others.

In the past, I wrote hot takes about Vietnam U20 and drew fierce backlash from readers. Back then I asserted that a massed defensive approach was a mistake and demanded a high press, and afterward I had to sit down until two in the morning, counting every pressing action and misplaced pass, to conclude that the midfield line achieved only a thirty-eight percent pass accuracy rate. My conclusion at the time was not necessarily wrong. But the way I proved it was.

What I wrote about U20 was not wrong, the way I proved it was.

That lesson taught me one thing: do not assign to a young collective the shortcomings that belong to the development system behind them. If Vietnam U23 transitions slowly at the 2026 Asian Games, that could be the players' fault. But it could also be the fault of an entire football ecosystem that never taught them how to make decisions within ten seconds.

Germany's lack of a number nine is a symptom, not a diagnosis. I repeat this line here because it applies precisely to the situation of Vietnam U23. The red-shirted team's shortage of a forward capable of finishing is a surface symptom. The diagnosis lies in the striker development pipeline, the stage where young players are converted into professional-level scorers.

Among the twenty-three names at the Asian Games, the number of players trained purely as central strikers can be counted on the fingers of one hand. Most are attacking midfielders or wide forwards pulled inside. This is not the coaching staff's fault. They simply work with what the system produces.

When the stadium is empty, the noise disappears and the data begins to speak. At the Asian Games, the stadium is not empty. But tournament pressure has a similar effect: it filters out decorative play and keeps only the substantial. That is a good environment for measurement, if the measurer knows what they are measuring.

I believe the quarter-finals are not the end point, and this is where I may be wrong.

There is another reading, colder and better grounded. If the VFF sets a quarter-final target, then the quarter-finals becomes an invisible ceiling inside the players' minds. When the team clears the group stage, performance pressure vanishes, and young players often slip into a state of quiet satisfaction. This state does not show up in statistical tables but it shows up in every duel missing one percent of intensity.

If that happens, the quarter-final target will transform itself into a trap of progress. This is a hypothesis, not a conclusion. I have no data to prove it, and football does not need you to believe, it needs you to verify. I will track Vietnam U23's one-on-one duel metrics in the first half of the quarter-final, should they reach it, to test this hypothesis.

A second reading also deserves a place on the table. Sixteen returning slots can be an advantage, but they can also be shackles. When a group of players has played together for a long time, they form habitual combinations. Against familiar opponents, habit works well. Against an unfamiliar and stronger opponent like Uzbekistan, habit becomes a weakness because it makes the team slow to adapt.

I have witnessed this at club level. A squad stable for two seasons suddenly plays poorly when meeting a newly promoted opponent with an unfamiliar style, simply because they no longer have the reflex to improvise. Stability and flexibility are two virtues that often exclude each other. Coach Dinh Hong Vinh will have to choose.

And here is where I interrogate myself once more. I once predicted Brazil would be eliminated by Croatia, getting the result right but the reason wrong. I cited Richarlison not being a pure number nine, but on reviewing the data, the real problem lay in midfield, where Casemiro won only three of nine duels. A number can get the result right but the cause wrong. I do not want to repeat that mistake with Vietnam U23.

Every debate has a layer of data that has not yet been turned over. The layer I have not been able to turn over here is the actual minutes played by each U23 player in the V-League last season. That is a more important metric than any youth achievement table, because it shows who is genuinely playing football in an adult environment and who is merely sitting on the bench as a promising talent.

If I must offer a verifiable judgement, I will bet on three things.

First, Vietnam U23's ability to clear the group stage depends almost entirely on the results against Kuwait and the Philippines, not the match against Uzbekistan. Coach Dinh Hong Vinh's team should approach the Uzbekistan match with a measuring mindset rather than an all-out battle mindset. A controlled draw against Uzbekistan is worth more than a lucky win against the Philippines.

Second, the minutes played by young players in the V-League next season will rise significantly after the Asian Games, regardless of the team's results. The reason lies in the fact that club coaches need data on players' capacity to withstand pressure, and the Asian Games is the only place that generates such data within a short time frame.

Third, and this is what I hope for most: at least one player from this list of twenty-three will break into the Vietnam national team within the next twelve months, not because he shone brilliantly at the Asian Games, but because he proved his ability to hold a position steadily within a system that demands tactical discipline.

The Asian Games is not a ticket to step immediately up to the national team. But it is regarded as a key for Vietnam U23 to prove their ability to Mr Kim Sang Sik as well as club coaches. Only by gradually securing a starting spot in the V-League will the door to the Vietnam national team open wider.

What I want to see at the 2026 Asian Games is not a medal, though a medal would be wonderful. I want to see a young team that knows what it is playing for, knows that every touch is a recorded line of data, and knows that the person sitting in the stands watching them is not merely counting goals.

Being wrong at the 2026 World Cup taught me more than being right for an entire season. I hope this U23 generation will also learn from its own mistakes at the Asian Games, whatever the final result. Because in football, the thing that lasts longest is not the scoreline, but the ability to read that scoreline again and understand which road you took to get there.
