He [Sir Alex Ferguson] used to play tapes of Bill Shankly talking. I remember that and a singer he liked. I don't know who it was but it was crap. He played it on the team bus too, and all the boys hated it. Until one night it got chucked away. If he's still wondering who threw that tape off the bus, it was me. So maybe he was right and I'm not to be trusted.

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

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 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.

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.

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

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.
