Vietnam U23 vs China U23: How to break through the opponent's "concrete" defense that hasn't conceded a goal yet.
Vietnam U23 faces an immense challenge in the semi-finals of the 2026 AFC U23 Championship against China U23's unbeaten defense. Exploiting the slow reaction time of their defenders, who are over 1.90m tall, will be key.
For coach Kim Sang-sik and his team, the 2026 U23 Asian Championship semi-final against China is not only a competition for a place in the final but also a rigorous test of their attacking prowess. Their opponents from the world's most populous nation are creating a strange phenomenon: reaching the top four with only one goal scored but maintaining a perfect clean sheet throughout the tournament.
"No-fly zone" with defenders over 1.9m tall.
The success of the Chinese U23 team so far is built on a foundation of iron discipline and superior physical attributes. Coach Antonio's team has transformed the penalty area into an impenetrable fortress thanks to its players' ideal height.
The heart of this defense is players like Peng Xiao (1.89m) and Zhang Aihui (1.91m). With their long strides and excellent aerial ability, they completely neutralized Uzbekistan U23's attempts at long balls in the quarter-finals. In addition, goalkeeper Li Hao is displaying brilliant form, becoming a strong contender for the best goalkeeper award of the tournament.
The "slow attack" tactic to overcome sluggishness.
From Uzbekistan's defeat, coach Kim Sang-sik surely realized that traditional cross-and-header tactics would be a wasted effort against these "giants." Instead, the Vietnam U23 team needs to utilize their agility and low center of gravity to exploit their opponent's Achilles' heel: their slow reaction time.
The optimal strategy proposed includes:
- Low horizontal tension:Shots that cut across the face of the goal make it difficult for tall defenders to react in time or easily lead to own goals.
- Seabed intrusion:Dribbling skillfully along the byline and then passing the ball back to the second line will force the opposing defense to constantly turn around, exposing deadly gaps.
- Take advantage of speed:Use short through passes to allow speedy players to break free, taking advantage of the slow pace of Peng Xiao or Zhang Aihui.
Beware of Coach Antonio's "lulling" trap.
One point worth noting is that the Chinese U23 team often proactively concedes possession, opting for a defensive formation in the center to force opponents to the flanks. This style of play easily creates a sense of complacency in opponents who perceive China's attacks as "harmless".
Former Uzbekistan U23 coach, Ravshan Khaydarov, once warned that superior ball control does not guarantee victory against this "concrete" defense. Just a moment of carelessness in defending against counter-attacks or set pieces could cost Vietnam U23 dearly against their opponent's extreme pragmatism.
The upcoming semi-final match demands that the Vietnam U23 team not only possess cunning in their finishing but also maintain a cool head to stay patient. Direct, low-pressure attacks targeting the opponent's weak points will be key to unlocking the door to a historic final.
