Chelsea defender Toni Rudiger says his aggressive approach comes naturally.

Rudiger is known as one of the Premier League's toughest players.

He said, "It's not that I want to play or something like this, because he's also I think a master of the dark side, so you always have to be careful when you play like that because sometimes it goes in your favour and sometimes it doesn't go in yours.

"I don't know why I have this. I have something in me that when I see something that doesn't matter or if I get like kicked or something like this, then I'm ready to go. Then I don't need any extra motivation from anybody, let's say, in a football way.

"It's like this in football sometimes. You can get kicked, it is what it is at the end of the day. It's competition, it's sport, but it's not like you want to hurt someone and as long as you don't go over the line, for me everything is fine."
