Napoli defender Kim Min-jae says he'll play through injury to face Brazil in South Korea's World Cup round of 16 tie.

Kim was missing from victory over Portugal.

"I was sad not to be on the pitch against Portugal and it's hard to watch from the bench, but the injury meant I was not at 100 per cent and in such an important match, we decided it was best not to risk it," Kim told reporters in the mixed zone.

“I want to do everything possible to play against Brazil, even if I get a more serious injury doing it."
