I want players who are always striving to improve.

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.

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

Do I miss football in Scotland? It keeps you really alive, that's for sure. Your heartbeat fluctuates. I'm flatlining at the moment which is actually quite nice but you need to go up and down to stay alive.

I did think there were one or two referees who had a personal thing against me. It wasn't them versus Celtic - it was them against me! I just think they wanted to take me on.

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

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.
