Vietnam U23 kicked off their 2023 Asian Games campaign with a 4-2 victory over Mongolia U23 on September 19, 2023. The win in Hangzhou provided a successful start for Vietnam in the group stage, though the scoreline suggests a more challenging contest than anticipated. Vietnam started brightly and raced into a two-goal lead within the first half-hour, seemingly on course for a straightforward win. However, Mongolia displayed great spirit, pulling a goal back before halftime to make it 2-1. Vietnam restored their two-goal cushion early in the second half, but Mongolia again responded to make it 3-2, causing some nervous moments. A late fourth goal for Vietnam finally sealed the three points. This match result gives Vietnam a crucial first win, but also highlights defensive issues to address for the tougher tests ahead in the tournament.
