The Intensity of Football

BBC SPORT Football My Club Wigan Athletic Jewell resigns as Wigan manager:

"It is not an easy thing to walk away from somewhere and something which has been such a part of your life for so long. The intensity of football at the highest level, although completely addictive, is also draining. I feel I would be kidding the chairman, my players and the supporters if I was to carry on without being able to put in the energy and dedication I know is required to be successful at this level."
