Fitness is a curve. You can be Lance Armstrong, or you can be really out of shape at the opposite end. People enter the curve wherever they are and then they can move up the curve, by better nutrition and better exercise.

I like to be able to control which players I'm working with. Because it doesn't matter how good a coach you are if the guys you're working with think they already know it all. You need a response, you need to feel they're trying. I want players who are always striving to improve.

Are there Martians out there? I haven't got a clue. Is there life out there? I have no idea.

He [Sir Alex Ferguson] used to play tapes of Bill Shankly talking. I remember that and a singer he liked. I don't know who it was but it was crap. He played it on the team bus too, and all the boys hated it. Until one night it got chucked away. If he's still wondering who threw that tape off the bus, it was me. So maybe he was right and I'm not to be trusted.

Believe me, you need good people if you want to make good players.

If you keep asking me questions, I will continue to find excuses.

Everybody at Barcelona loves Messi. They can't speak highly of him.
