Believe me, you need good people if you want to make good players.

I like to be able to control which players I'm working with. Because it doesn't matter how good a coach you are if the guys you're working with think they already know it all. You need a response, you need to feel they're trying. I want players who are always striving to improve.

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

I tried to talk to the ref but it is easier to get to see the Pope. If I'm in London again and I get mugged I hope the same number of people turn up to protect me. There were six police, four stewards and even a UN peace observer out there.

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.

I'm not saying you have to be married to be a good footballer. I'm just saying it felt strange to come to a club where there are only three members of the first-team squad that are married. You need responsibility in life.

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.
