You don't get to be world champion unless you do that.

Ask José Mourinho, he wouldn't know a thing about me, my sport - he knows football, and to get to high levels you have to be insane, nothing else means anything.

Whoever said it's tough at the top is talking absolute sh*t.

Victorious. I feel that is why I did all the training, why I make the sacrifices, that is why I got into the shape I am in. I feel I have won, that's millions more coming my way, I feel great.

You need to be able to hit, kick, grapple, wrestle, but for me so much of this is about the mind, about feeling you are in complete control of the space around you, and you know what to do at any moment. That is a wonderful feeling, but it doesn't just happen, you have to work for it, train for it, think about it all the time.

I mean I love movement. I mean the energy that comes from the way I move. We get energy from how we move. I mean the control I get from knowing everything about how my body feels and how it is working.

It's important to stay hydrated - first thing I do in the morning is stretch and drink water.
