The only fight worth fighting is to give all children equal opportunities regardless of race or gender, to judge individuals on their qualities and not their backgrounds. The victory won't come when nobody feels able to voice racist abuse, but when nobody thinks of doing so in the first place.

White players always said to me: 'You can call me 'a white so and so,' I don't mind.' But that's because society has indoctrinated us over the past 400 years to think that that's like saying 'you handsome so and so.'

I'm quite unfit. It's the motivation that's the problem, I need a goal. When I was a professional footballer I trained every day because I had to.

I felt I had to take the Celtic opportunity. You quickly learn that any managerial vacancy attracts up to 60 or 70 applicants, so you need a good reason to turn a job down. A start is a start.

Football has a future. I don't know what that future is. I'm a physician.

People wrote so negatively about me, but generally, the people who are familiar with football know my strengths and abilities.

Loyalty is a big part of football, and it shows if you are a real man or not.

I was forced to learn a lot about psychology as a player, and as a captain to get the best out of others. There's still a lot of scepticism about it in sport and the workplace, but dealing with fluctuations of form, and pressure, and being away from home are more important than your cover-drive.
