-Mancini, 1 dimensional, negative football, can't influence games from the touchline, not playing right formation to suit players.
-players, some of them not good enough, not enough squad depth, not enough pace or commitment in some of them.
-Catering-overpriced and poor quality, with all the money that should have been remedied in 3 seasons.
-smoking-should have more done to prevent it, instead of the random, half arsed approach.
-stewarding-stop kicking people out before talking to them first and apologise when you mistakenly kick someone out Peter Fletcher instead of not being courteous and polite.
-family friendly-kids should be going for the right reasons and the club should be listening and cutting down on making it so cheesy, it doesn't have to be core adult and really unfriendly but there's a balance yet all we ever get is Hugh Ferris blabbering on all over the place on really trivial things that aren't relevant to anybody but keeping a few half arsed kids and their families "Happy". Stop emphasising everything as family friendly and just open it to everybody and make it about City fans as a group instead of intentionally trying to segregate everybody.
that's off the top of my head.
