Fourteen weeks before the Mendes fight I tore 80 per cent of my ACL [anterior cruciate ligament]. That is the main ligament for stability. Every day in that training camp when I was working my way back, I was saying "real champions fight through any adversity". That is why I am a real champion and he is not. Look at my eye [he had seven stitches put in an old wound after an injury in training the night before we met]. Fighters fight on. Aldo got scared, he went running and I worry he will run again.

I think I am the greatest fighter in any class.

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.

It is the most powerful submission in the sport. It is a beautiful thing. You're holding them into you, their back is on you, and you are basically choking them gradually like a boa constrictor and once you've got them, the pressure goes on and they have to submit or they are going to stop breathing. It happened to me early in my career, and I panicked, and gave in, I tapped out too early. I learned a lot from that. I learned from it, learned how to do the move better, learned how to avoid it being done to me.

Seems like people get obsessed about times and numbers and weights and that - I'm obsessed with winning.

Getting enough protein is important when I train, to help build muscle and recover, so I'll supplement with protein shakes.

I think we should all focus on who we are, what we want to do, and do it. That is my way. I don't know why anyone would want to do that politics stuff.
