A friend of a friend knew him when he stayed in his flat in the Gorbals (I think) and used to say they were up to all sorts.
Maybe didn't help that perhaps his heart was never, truly, in it with us.
Don't think that was the case at all. Most 18 year olds earning the money he did aren't going to be very mature with it, especially when they think they've already made it. He's hardly the first young footballer to fall into that trap either.
