Despite the public persona, he is renowned for the humour and enthusiasm he translates through to his players on the training pitch.

He has said: "The really good coach is the one who is happy to work. The drive, the hunger, the passion must be inside you because players need to recognise that you care."

But he has also adapted his methods as player power has increased over time: "You have to deal with that and the one thing you must have is control. There has to be a strong discipline in the training and in general."
