Grealish is a talent but he came back after summer in poor shape and not focused, probably because of his party boy lifestyle. He has had niggling injuries but his recovery from them will be impacted by his behaviour off the pitch. He doesn't seem to realise he is not at Villa any more, he is at an elite club. If he doesn't sort himself out quickly Pep will dump him. Pep has a track record of being ruthless. I defended him all last season but I have seen too many players over the years waste opportunities because they think they are bigger than the club.
