I just cant shake the feeling he's got some big injury/off field issue they can't fix and that's why he seems to be available so incredibly cheap for who he is. His ego, demands and attitude have never seemed an issue with them before.I'd suggest the biggest problem is that PSG have lost €600m in the last 3 seasons and Neymar's getting a lot of money from them.
Secondly I get the sense he'd like to move away and take another run at the top trophies before he's past it.
He's also been injured for about a 1/3rd of his career at PSG.
And if you're being really cynical, ask how many of the Brazilian superstars have made football a priority past 30? Ronaldinho, Ronaldo, Rivaldo, Robinho, Kaka, Adriano...all washed up by 30.
