Nguyen Quang Hai decided to withdraw from Vietnam’s squad ahead of the 2026 FIFA ASEAN Cup because of injury. Observers said his decision was also shaped by accumulated fatigue, and stepping aside is described as a respectful, responsible act.

At the same tournament, Xuan Son, Hoang Hen and Tai Loc were all sidelined by injuries. Their cases show the cost of playing while not fully fit.

The article says that a player’s physical condition must carry equal weight with reputation, experience and club form when the squad is chosen. Coach Kim Sang Sik must check fitness, talk with clubs and avoid pressuring players to accept call‑ups when they are not fully fit.

Choosing healthy players can help Vietnam win more matches. Fitness should be as important as fame when the national team is selected.
