I'm quite laid-back but some people say I'm unemotional. I don't get carried away with success and similarly I don't get depressed when something bad happens. I didn't take it personally when rival fans threw banana skins at me when I was playing for Liverpool. I can't control 50,000 idiots shouting at me, so why would it bother me?
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.
Most people would accept that we are, to a certain extent, products of our environment.
Yes, my clothes don't reflect my personality at all. Because I'm a very straightforward and serious person. My clothes are much flasher than I am. Yeh. Yeh, yeh. It's a good contrast. I don't think your clothes should reflect your personality... keep people on their toes.
In the 1970s people were afraid to call me black because they thought it was an insult. They would say 'coloured.' Now it has gone full circle. It's not an issue. The intention is the most important thing.
As I've been saying for decades, as long as racism exists in society, it will exist in all facets of society. Until we eradicate it from society, football will be like any other industry.
In the 1970s you would have had lots of black goalkeepers and defensive midfield players but never made it professionally because the perception was, 'You don't think too much, you can't play in positions of responsibility so you play on the wing or up front.' Lots were lost to the game because of the perception.
Generally speaking, ego isn't a good thing. Humility is the most important quality in a human being.
How many black people are there in the higher echelons of any industry? We can talk about journalism, we can talk about politics. So why should football be any different?
Britain has always told the world that being British is about the humanity, compassion and moral fortitude that we have. All great things that we are supposed to have spread across the world. A leave vote now says that we don't really care about anyone else, we don't care what happens to the European Union.
For a long time, images of black men with big lips and a round head were used to make us feel inferior, but it doesn't need to be like that, we don't need to self'loathe. We can change the narrative.
Yes, I went through overt racism as a footballer in the 80s and early 90s but that was, or is, nothing compared to what the average black person in the inner cities of England goes through every day.
