Because in the time it takes them to play one game for City, the young men whose primary reason for moving to Eastlands will more than likely have a pound sign in front of it, would be educated in the very essence of the club and its supporters: eternal hope, unfailing loyalty and self-deprecating humour, not to mention an in-bred hatred of neighbours Manchester United. plus the inflatable bananas and Noel Gallagher of course.

Afterwards the Italian tries to lift his shattered players in the dressing-room, chairman Khaldoon Al Mubarak places a consoling arm around Cook and the local radio reporter looks close to tears.
