Following Vietnam’s 4-0 friendly win against Myanmar on July 18th, Nguyễn Đình Bắc expressed dissatisfaction with teammate Nguyễn Xuân Son's on-field actions. The incident occurred during the latter stages of the match, suggesting a disagreement over gameplay. Specifically, Bắc appeared unhappy with Son prioritizing a shot on goal rather than potentially passing to a better-positioned teammate. While the exact nature of the discontent remains unspecified, it signals potential tension between the players. This occurred despite the dominant victory for the Vietnamese national team. The situation highlights the competitive spirit within the squad and the pressures of performing in international friendlies. Further observation will be needed to determine if this is an isolated incident or indicates a larger issue within the team.
