Joe can't play his football.
It doesn't matter how good or bad he is or how much or little leadership he has, that disqualifies him from playing for the club.
If we had Andy Carroll on the books and he was not only the biggest yes man but also a City legend who scored a goal a game for us he'd be gone too because he doesn't play our football.
I don't know under what pretence people wanted us to keep Hart upon. He'd never be on the pitch, he'd be the third choice keeper. If we all love him so much like everyone is making out, is that what you want for him? To throw his international career away and rot not even in the reserves because we should hoard players?
He didn't need to handle Joe because he was going. He has handled Yaya though, and Kompany, and Zab and Aguero, and all of those who are fit are performing for him.
So not only has he not thrown out these dressing room leaders but instead he's got them playing for their places for the first time in 5 years. That's leadership.
