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

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

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 think if you've managed Celtic or Rangers you can go on to be Prime Minister of Great Britain, it's that hard.

The reason I became a manager was to have full control over training. If you are a coach, you are bound by what the manager wants you to coach. The other reason is that I just like the company of football people.

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

If I was English I'd kill myself
