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'm a better coach now than when I joined Celtic. The longer you stay in any job, the better you become. If you lose your drive, your enthusiasm, your imagination, that experience is no good.

Good players win you games, good formations stop you losing them.

I did think there were one or two referees who had a personal thing against me. It wasn't them versus Celtic - it was them against me! I just think they wanted to take me on.

If I was English I'd kill myself

Paul Scholes has been the best England midfield player for 30-odd years. You'd probably have to go back to Bobby Charlton to find someone who could do as much as Scholes. When the ball arrives at his feet he could tell you where every player on that pitch is at that moment. His awareness is superb.

He could have done one of three things. He didn't do either.
