I think one of the problems give Gazza is, is his head, he's still a 10 year old boy who just wants to kick a ball 24/7. He's never grown up and, since he left football, has no idea what to do to fill his days.
He isn't reliable enough to work in coaching or be a pundit but just being involved in the game could have given him something to get out of bed for. It's a vicious circle and it's all to late now I feel.
I think you're right there. I'm no big football fan myself, but my OH made me watch his Life Stories episode with Piers Morgan and I learnt a lot about him that I didn't know, and found myself starting to like him. I feel very sorry for him.
