I think the lack of smiles upon arrival and how he seemed pissed of to be back at the club is the main reason I would want him out. Despite of anything that happens on the pitch, Pep wants unity, and you won't get that if players don't even want to be there.
It's time to freshen up and move on to you younger, hungrier players who want to turn up to work for pep and their team-mates. I for one hope I don't see him play for City again. I'm not here to talk about how great he's been in the past, nobody cares about what he did, the whole club is looking forward and looking to move forward.
