I don't care about anything I don't need to care about.

I've read a lot of books on the laws of attraction, and in my home I have a big book on Muhammad Ali, which I've read, because he is like a hero of mine, but other than that, no, I'm not a big reader.

If people want to believe in this god, or that god, that's fine by me, believe away.

I think I am the greatest fighter in any class.

Pain is part of the sport.

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.

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.
