Think every one is different mate, I think it was more the case of his family didn't settle rather than him, so he probably didn't take the move thinking he would be away from his family.
A lot of people have the view that footballers are on loads of money so they should just get on with it but if you can get the same kind of money and keep his family happy I can understand the move.
I quite recently got offered a job for **** loads of money, it would mean working abroad for a few weeks at a time which I quite liked the sound of, however the reason you got **** loads of money was because when you got out there it might not just be a couple of weeks, the lad that was going to get me the job and would be my boss got sent to Spain in early October for 2 weeks, he didn't come home till march. I know it's an extreme example but sometimes money isn't everything
