Coach Dinh Hong Vinh: U23 Vietnam ready for any quarterfinal opponent at Asiad 2026

In the sixth minute at Nagoya, the ball was already in U23 Vietnam's net. Uzbekistan attacked at high tempo from the first whistle, while Vietnam's defence had not yet settled into position. One moment of lost concentration, one line-breaking pass, and all the cautious calculations of the coaching staff were pushed into an uncomfortable chase for an equaliser. The match does not truly begin when the referee blows the whistle, but when a defender decides to leave his position. For U23 Vietnam, that moment came too early and cost too much. The 0-2 loss to Uzbekistan in the final Group C match at Asiad 2026 left fans disappointed, but more importantly: the quarterfinal ticket was already secured before the ball rolled, thanks to their results over three matches. The question now is not whether they reached the knockout stage, but which squad will step into the do-or-die match on September 25. U23 Vietnam entered the final group game having already completed their minimum objective. Throughout the group stage, they were forced to rotate personnel constantly due to injuries and suspensions. Coach Dinh Hong Vinh admitted the team lacked long-term preparation: the squad was a mix of players who had competed in the 2026 AFC U23 Asian Cup and entirely new faces. Many key players of the U23 generation had been promoted to the senior national team, forcing the coaching staff to rebuild from scratch. Uzbekistan, by contrast, almost retained the squad that played at the AFC U23 Asian Cup — a group that had competed together across multiple tournaments and won all three group matches. They arrived in Nagoya with confidence and understanding that U23 Vietnam could not match at this moment. Combined with the heat that had persisted in Nagoya since September 13, the final group match was not only a tactical contest but also a brutal physical test. In the post-match press conference, Coach Dinh Hong Vinh did not make excuses. He congratulated Uzbekistan on a deserved victory, explaining the early goal came from the opponent's high tempo and a moment of defensive lapses. After conceding, U23 Vietnam regained control of the ball and created several chances in the first half, but failed to convert them. He was blunt: 'I am not satisfied with the ability to exploit attacks in the final third. Our playing style was sometimes slow in tempo.' The question posed before every ball in that area — pass sideways or penetrate, slow rhythm or fast rhythm — still had no consistent answer. When a team cannot turn territorial control into goals, initial caution becomes a double-edged sword. He also mentioned an unverifiable hypothetical: if U23 Vietnam had equalised before the end of the first half, the situation could have been different. The one bright spot Coach Dinh Hong Vinh repeatedly emphasised was the fighting spirit of his players. He expressed satisfaction with the attitude and fighting spirit of the whole team, despite the result. In a knockout match, when the gap in class is narrowed by determination, this could be U23 Vietnam's most powerful weapon. The bigger concern was not the scoreline, but the injury list. Xuan Bac, the central midfielder regarded as the rhythm-setting conductor, could not continue after sustaining an injury. Coach Dinh Hong Vinh confirmed that his absence reduced the ability to control the rhythm of transitions. At the press conference, he added that Nguyen Thai Quoc Cuong, Xuan Bac's partner in central midfield, was also injured. Thus, the first-choice midfield pivot is entirely unavailable for the quarterfinal. This is a double loss: U23 Vietnam did not just lose players; they lost the exact functional unit the coaching staff relied on to control the tempo. Against high-pressing opponents, this midfield pair was the first shield in front of the defence and the launch point for line-breaking passes. Losing both means the entire midfield circulation system must be rebuilt from scratch, against one of the tournament's strongest sides. Who will that opponent be? In Group D, South Korea and Saudi Arabia are competing for top spot. The Group D winner will face the Group C runner-up, putting U23 Vietnam in line to meet one of them. Whether it is South Korea with their high-intensity pressing and tactical discipline, or Saudi Arabia with superior physical strength and technique, U23 Vietnam will face a team currently above their level. Coach Dinh Hong Vinh refused to pick an opponent: any team reaching the quarterfinals is strong, and his side must be mentally ready. But from a tactical perspective, both profiles attack precisely U23 Vietnam's biggest weakness right now: a depleted midfield and vulnerability to pressure in the opening minutes. Time is also not on U23 Vietnam's side. The final group match was on September 22, the quarterfinal is on September 25 — only three days to recover. The prolonged heat in Nagoya since September 13 makes fitness a problem that cannot be solved tactically. Coach Dinh Hong Vinh said the team needs to recover well to regain optimal condition, and the staff will assess each player's fitness before deciding the lineup. But with constant rotation throughout the group stage, fatigue is accumulating. Based on my experience following U23 Vietnam's matches, my biggest concern is not who the opponent is, but how much energy the players have left after the 60th minute. In extreme heat and a congested schedule, second-half substitutions will reveal more than any tactical diagram. Looking back, the loss to Uzbekistan should not be blamed solely on the coaching staff. It is the inevitable consequence of a development model: U23 Vietnam is paying the price for the senior team's success. The best U23-eligible players keep being promoted to the national team, leaving the U23 side no time to mature together in a short tournament like the Asiad. This benefits Vietnamese football in the long run, but it creates a cohesion gap that no coach can fill in a few weeks. Coach Dinh Hong Vinh's phrase 'ready for any opponent' is sound media messaging, but the truth on the pitch is different. Every formation is a lie when the viewer stands in the stands; the truth lies on the grass, where the spaces move. The biggest space right now sits directly in front of U23 Vietnam's defence — where Xuan Bac and Quoc Cuong used to stand. The quarterfinal on September 25 will be the most accurate test of Coach Dinh Hong Vinh's 'ready' declaration. I do not write to praise a goal, but to point out the steps that led it there. If U23 Vietnam keep a clean sheet in the first 15 minutes, that is a sign the system still functions despite missing personnel. If they concede early again as against Uzbekistan, the question is no longer who the opponent is, but whether Vietnamese youth football needs to be restructured around cohesion time and squad stability. Southeast Asian football has seen many talented young teams crumble because they lacked time together. U23 Vietnam now has only three days to answer.
