I don't watch the news, I don't care about politics, I don't care about other sports.

To do anything to a high level it has to be total obsession. 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. I respect all forms of movement and lifestyles, but I am in a bubble. I wake up, it is in my head; I go to sleep, it's in my head, 24/7.

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

The surface below your feet is so special. It is not like a boxing ring, not like a wrestling mat, it's its own thing, and when I am there, I am floating, I am moving with total freedom, I am free. And when you know, when you just know you are going to win, like I do, there is no better feeling.

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.

I am not a big crier. But I'd say it was after the Mendes fight. It was not because of the fight as such. It was everything leading up to it. It had been such a tough time. When I did my knee, I had some very dark times. Life is all about ups and downs and I'd say there had been a lot of downs, but I got through it, I won and after the fight, I was standing in the shower and I was crying, just letting it all go.

Sometimes the truth hurts. It hurts because they have a weakness - and I exploit weakness.
