It wasn't an easy decision to leave out Bobo, because I could have done that with two or three from the back four. But there's a limit to the players you have and the changes you can make. The reality is we're not defending well enough. But we just have to plug on. There's no magic formula.

If I was English I'd kill myself

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

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.

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've had to take a lot of stick down the years but the one thing that really got to me was when someone questioned my integrity. It's the one thing that really grates with you.

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