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.
