Nguyen Dinh Bei's header goes in, and Fan Junhai scores with a follow-up shot. All of a sudden, the Vietnamese team overtook the score, which was unbelievable. However, in the end, it was the Japanese team with the superior strength to complete the counterattack, Takumi Minamino scored with a low shot to equalize, Nakamura Keito scored from a distance to overtake Japan, and Ueda Kiyo scored a late goal to seal the victory. The final score was set at 4-2, and the Japanese team refused to cause an upset and defeated the Vietnamese team. As the No. 1 team in Asia, Japan was humiliated by Vietnam who scored 2 goals.
