Vietnam faces new test at FIFA ASEAN Cup 2026: Compressed preparation, injury risks and lessons from regional history

Vietnam is entering a rushed preparation phase for the FIFA ASEAN Cup 2026. Under coach Kim Sang-sik, the Vietnam national team faces major challenges. Theoretical preparation time is only about two weeks, while key players from CAHN have only 5-6 days in camp. In detail, Kim's tactical system is a possession-oriented 3-4-3 or 4-3-3 with quick pressing, but late integration of players will degrade execution quality, especially in set-pieces and pressing coordination. Players Quang Hai, Dinh Bac, Nguyen Filip, Van Hau, Van Do, Thanh Long, Quang Vinh will arrive late, carrying fatigue from club matches. CAHN will play Champions League Elite against Osaka on September 15 and V-League on September 20. Technical issues from the previous ASEAN Cup persist and are harder to resolve now. Physical conditioning is a major risk due to congested schedule. Vietnam is a regional powerhouse, but preparation asymmetry reduces effectiveness. The September 26 opener against the Philippines is a test of Kim's adaptability.
