He must be sold asap, if Juve is really interested.
But he is too much of a scapegoat - everyone should be able to see now, that he isn't this squads main problem.
Busquets/Suarez/Alba deserves as much hate as Rakitic, the problem really is too many old players with too much power.
Best we can hope for now is Pep coming back and selling half the squad to start again with younger players.
If he comes and we get the right people in (not even ready-made world-class players), then we can get rid of all of our players above 30 (except Messi).
