whilst I get the fact that some supporters want to defend Joe and feel that he is being treated badly, the fact is that there is little sentiment in professional football, and players are now paid astronomical sums of money for carrying out their chosen profession.
If Pep doesn't fancy Joe, for whatever reason ( I do not know anything about his alledged issues with the club, previous managers etc ), then Joe, and supporters, are going to have to accept the fact that he is no longer the no 1 choice at City, and do whatever is necessary to preserve the rest of his career, be that moving to a PL club or abroad.
Sorry is this is too simplistic and harsh for some, but I don't see an alternative.
