As U23 Vietnam heads into the AFC U23 Championship 2026 in Saudi Arabia, one reality looms large: the team is no longer an enigma.

The squad arrives at the tournament after a densely packed and relatively successful 2025 campaign. From regional events to international friendlies, coach Kim Sang Sik’s men featured regularly, gaining experience and demonstrating resilience.

But this consistent presence also came at a price - U23 Vietnam’s style of play and tactical framework are now familiar to group-stage opponents such as hosts Saudi Arabia, Jordan, and Kyrgyzstan.

The element of surprise, whether in formations or strategy, has largely evaporated. That lack of unpredictability presents a major obstacle for coach Kim Sang Sik, who must now devise new approaches if he hopes to catch rivals off guard.

The challenge is compounded by the fact that the team’s core lineup has remained stable across multiple tournaments. Recognizable names like Dinh Bac, Van Khang, Phi Hoang, and Ly Duc have become cornerstones of the squad - and obvious targets for opposing analysis. The likelihood of creating unexpected breakthroughs is therefore significantly reduced.

What happens when there’s no more surprise?

Being predictable means each match at the AFC U23 Championship becomes a grueling tactical battle. U23 Vietnam must discover innovative methods to break free from anticipated opposition strategies.

Conversely, the Vietnamese coaching staff has limited access to reliable information about their group-stage rivals. Teams like Saudi Arabia, Jordan, and Kyrgyzstan have not played as extensively over the past year, making scouting more difficult.

Without video footage or detailed statistical profiles, coach Kim Sang Sik faces a steep climb in preparing counter-strategies - especially against opponents known for their physical prowess and continental experience.

The lack of intel is only one of several concerns. There’s also the weight of new expectations.

Unlike past editions, U23 Vietnam may no longer be considered the underdog. This elevated status brings pressure. The young players, already tasked with tactical execution, must now manage rising demands and maintain composure. Every mistake could be capitalized upon, and mental resilience may prove decisive.

Yet, hope is far from lost.

Perhaps the biggest advantage for U23 Vietnam is the team’s cohesion. Over the past year, the squad has played nearly 20 matches - friendlies and official tournaments combined. That level of continuity has built deep mutual understanding, visible even in the smallest in-game movements. It’s something their rivals simply don’t have.

If U23 Vietnam can maximize this chemistry, stay mentally tough, and remain flexible in each match, the team still has a real shot at delivering strong results. It may even advance further than in recent tournaments.
