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.

All the really good players I know, they all knew right from wrong. So many of them don't learn that at home nowadays.

Thomas Gravesen thinks he's broke his hand, but I told him that you play football with your feet and not your hand.

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

If you keep asking me questions, I will continue to find excuses.

Are there Martians out there? I haven't got a clue. Is there life out there? I have no idea.
