It's a bit like walking down a long, dark corridor never knowing when the light will go on.

As a player I won things, had a special 10 years under Martin O'Neill [at Leicester and Celtic] and played in some great teams, beating Manchester United and getting to the last 16 of the Champions League. As a manager, I don't know if I will top this; I hope I do, because I am still young and am still learning. But this is up there with anything I have achieved, not just in my football career but in my life.
