South Korea saw off Colombia with two goals scored before the game was even an hour old. Son played the whole match, and opened the scoring after 17 minutes.
The Tottenham forward returned to lead his team to victory in a potentially difficult match, with Colombia no easy team to beat.
But during the clash he made gestures caught on camera which have put him under the spotlight. He brought his hand to his mouth and made gestures that seemed to be asking that his opponents continued talking to him.
Son stopped in his tracks, turned around and directed his gesture towards one player in particular, before saying something which could have been perceived negatively.
