If, going by recent comments from Pep, that Nasri is training well, and could still have a future at City, surely the same applies to Joe? I don't believe that "you can't teach an old dog new tricks" Joe is 29, still plenty of life left in him, he can improve his passing, it is now a prerequisite, a primary skill that is needed, so he can either suck it up and fight for his place, adapt, or ask to leave.
Our keepers will be playing with Stones and Vinny in front of them, so it's going to become the norm to be passing to skilful defenders who can see a pass, so I assume this will be heavily worked on in training, so, he will get better.
Joe is a good keeper, if he can add distribution to his game, he will get his place back, that if if he wants to fight for it, and who's to say this isn't just Pep's way of challenging Joe to sink or swim?
