South Korea secured top spot in Group C of the 2019 Asian Cup with a convincing 2-0 win over China at the Al Nahyan Stadium.
Tottenham forward Son Heung-min, who was granted permission to miss the 1-0 wins over Philippines and Kyrgyzstan, was influential on his first outing of the tournament.
Son won the penalty from which Hwang Ui-jo opened the scoring after 14 minutes and provided the corner for Kim Min-jae to double the lead early in the second half.
It was a deserved win for Paulo Bento's side, who looked a far more convincing outfit with Son in their starting XI and his arrival should offer hope of a run into the latter stages of a tournament they have not won since 1960.
