I am not making a criticism of his achievements whilst at City, he was the right man at that time, he left us with great memories and shattered the dominance of the rag cunts.
He outstayed his time though and whilst he is charming and has nice hair, it does not detract from his arrogance, petulance and his self absorption. He left City with a dressing room in a state of civil war, he was rude, obnoxious and downright dismissive of people at the club.
His faults have been well documented by former players and that came to a head in the Wigan FA Cup final.
There is little point comparing him to any other manager we have had, they all have their foibles, it is Mancini's that were pronounced.
