The reason I became a manager was to have full control over training. If you are a coach, you are bound by what the manager wants you to coach. The other reason is that I just like the company of football people.

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.

Thomas Gravesen thinks he's broke his hand, but I told him that you play football with your feet and not your hand.

I'm not saying you have to be married to be a good footballer. I'm just saying it felt strange to come to a club where there are only three members of the first-team squad that are married. You need responsibility in life.

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

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.

People talk about footballers and they get a bad press when not all of them deserve it.
