This time around Son didn't play in the first two group games against Malaysia and Bahrain but scored the victor against Kyrgyzstan and was a starter in the quarterfinal win over Uzbekistan, the semifinal against Vietnam and Saturday's final. Of course, it's such an important game for him. "They showed real spirit and can be proud of themselves".
