I get the feeling a lot of politicians are there to help themselves financially, first and foremost. I don't really need to do that, and I thought if I could do something for sport in Scotland, that would be really fulfilling.

I've been in football a long time and people have problems through debt, drugs, drink and family.

I've had to take a lot of stick down the years but the one thing that really got to me was when someone questioned my integrity. It's the one thing that really grates with you.

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

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.

I think if you've managed Celtic or Rangers you can go on to be Prime Minister of Great Britain, it's that hard.

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