Mancini was an able politician and wearing the scarf and talking about ripping the banner down was good PR to ingratiate himself with the fans, but i'm not sure I ever fully believed that really cared in a more profound way then any other manager. Someone truly committed to the club wouldn't have been negotiating with Zenit and Monaco and (allegedly) handing his resignation the day after we won the league. All of this was part of a political power struggle that the club didn't need and he couldn't win. There was always a sense of tension and angst under Mancini, that might not have been entirely down to him as ego wasn't in short supply in that dressing room, but he seemed to be the fulcrum. Ultimately a great manager doesn't end up alienating everyone from the Kit Man to the Chairman and, most significantly, Kompany, Toure, Silva and Aguero.
Pep doesn't give the impression of being one of us - and there's still a whiff that the great Catalans are deigning to sprinkle their genius over a club with no history - but he doesn't play political games and end up at war with everyone at the club either. Under Mancini there was no real sense of collectiveness but with Pep we have the best team spirit of any City side since the Royle promotion team of 99/00. He's put together a team that is greater than the sum of its parts - 198 points with Delph and Zinchenko at left back - and that, arguably, is the test of any manager.
As for the football we play, the 2012 side had its moments, but it's nothing consistently comparable with the brilliance of what we had over the last 3 seasons.
