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

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

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.

It wasn't an easy decision to leave out Bobo, because I could have done that with two or three from the back four. But there's a limit to the players you have and the changes you can make. The reality is we're not defending well enough. But we just have to plug on. There's no magic formula.

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.

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

Do I miss football in Scotland? It keeps you really alive, that's for sure. Your heartbeat fluctuates. I'm flatlining at the moment which is actually quite nice but you need to go up and down to stay alive.
