In general, I like the healthy stuff and don't really have a problem with any of it.

I am in the fighting game, I don't care about anything else. I don't watch the news, I don't care about politics, I don't care about other sports. I don't care about anything I don't need to care about. This is my sport, it is my life. I study it, I think about it, all the time. Nothing else matters.

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

A fight is mental, not just physical and psychological warfare is absolutely part of that.

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.

One of the reasons I got into this game was because I wanted to learn how to get myself comfortable in uncomfortable situations. I grew up in a tough area of Dublin, and fighting was just part of your life. Boys fight, and I won some, but I lost a lot too, and I didn't like that, I didn't like that feeling of not knowing whether I was in danger, in trouble.
