Without Nguyen Van Vi due to injury, Vietnam face left-back puzzle at FIFA ASEAN Cup 2026

Nguyen Van Vi's limp as he left the pitch in the match between Thep Xanh Nam Dinh and Hoang Anh Gia Lai was the worst signal Vietnam received before the FIFA ASEAN Cup 2026. Coach Vu Hong Viet confirmed that Van Vi suffered a hamstring tear and needs more than one month to recover. That means he will almost certainly miss the group stage. Van Vi is not a silent left-back. He is known for his speed and ability to support attacks from the left side. For the national team, he plays a vital role in the tactical scheme, especially during transitions from defense to attack. His statistics show six goals in 18 appearances, which is rare for a full-back. Indonesian fans remember his attacking contribution against them, so his absence has added to their optimism. Vietnam are in Group B with Thailand, Philippines, and Pakistan. Opponents can now target the space behind the new left-back. Candidates such as Phan Tuan Tai, Doan Van Hau, and Cao Van Quang Vinh offer different strengths, but none can fully copy Van Vi's timing and speed in transition play. This is not just a personnel problem. It reveals an over-dependence on one player. The real test for coach Kim Sang-sik is whether the team can reorganize without changing its identity. The opening match against Philippines will be the clearest measure of Vietnam's readiness. Instead of focusing on the score, observers should watch how Vietnam move the ball after regaining possession and whether the new left side can handle direct pressure. Tactics are not magic. They require looking deeper and finding solutions within the system.
