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 think what I've actually achieved as a manager does sometimes get a bit overlooked, because all people think about is the media side of things. They tend to forget I've not done so bad.

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.

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.

It took me 35 years of being involved at a decent level of football to become manager at a great club like Celtic.

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 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.
