Son Heung-min has explained his emotional reaction to scoring a 14-minute hat-trick from the bench in Tottenham's win over Leicester City.

Spurs secured an emphatic 6-2 victory in north London, with Son playing an integral role.

The South Korean has struggled for form this season and was visibly emotional after scoring three goals.

"I just wasn't happy with my chances and performance-wise I was not happy and I was disappointed with myself," Son told reporters.

"Look, I'm born loving football and I am still in love with football. I think about football. I'm an attacking player and when I'm not scoring I'm not happy. How can I be happy if I have an unbelievable opportunity to score or make the chances?

"If I'm happy and I'm not scoring, I probably wouldn't be here. Sometimes when I go home, even if we've won the game. I'm still sad because my performance wasn't good, there are things I can do better and the mistakes I made because I missed the chances.

"I'm always thinking about football because I made it here and this is the way I am here. I still love football even in the tough moments and this is why I am here."
