If I was English I'd kill myself

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

Sometimes to go forward you've got to go to the depths of your own personal despair and claw yourself back. From that point, no matter what happens, you know you can do 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.

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

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.

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.
