Data from 120 V-League matches exposes the real crisis: Not fitness, but the moment of losing possession

In the 74th minute of a V-League 2026-25 Round 18 match, Công An Hà Nội lost possession in midfield after Nguyễn Hoàng Đức was pressured into a bad pass. Within 11 seconds, Thép Xanh Nam Định turned defense into attack and scored, exposing a gap of nearly 18 meters between the home team's defenders. Many observers dismissed it as individual error or poor stamina. But tracking data from 120 matches tells a different story: 61.7 percent of goals conceded by Vietnamese teams arrive in the final 25 minutes. The total running distance does not collapse late in games; what changes is the quality of running. After the 65th minute, the number of successful pressing actions drops from 14.7 in the first half-hour to only 7.2. The real crisis is not physical. It is the reaction after losing the ball. Vietnamese teams tend to push their defensive line high and their full-backs wide during possession, but they lack a structured plan when the first press fails. The average time needed to rebuild a compact defensive block is 11 seconds versus only 6.5 seconds for better-organized teams. Opponents with wingers who can run faster than 31 km/h repeatedly exploit the space behind the defensive line. Five substitutes have not fixed this problem. They have actually made the final 20 minutes more chaotic, because coaches often introduce three or four players at the same time, temporarily destroying the coordination needed for defensive transitions. Vietnam does not have a tactical identity crisis; it has a transition-management crisis. Coaches and academies must teach players when to press, when to hold position, and how to recover after a turnover. Until that changes, the same goals will keep repeating in the last quarter of every match.
