The Sun reports Stephen Aziz â who left the Etihad earlier this season â alleged the Italian was âarrogant, vain, self-centred and ignorantâ.
And he claimed it was hard to get the former Inter manager to even acknowledge him when they bumped into each other at training.
Aziz astonishingly wrote on Twitter: âNot my style to come in here and start to bad mouth someone but this guy was really a piece of work!!!
âArrogant, vain, self centred no manners ignorant just some of Manciniâs daily traits really made going into work a grind!! #karma.â
Aziz also claimed: âFans donât get to see what really goes on and day 2 day running, 2 years there seeing him every day was hard work getting a âgood morningâ
âMcfc on the other hand what a club to work for some great players and staff nice down to earth ppl loved working there!!! #MCFC
âNot saying he didnât do well to win trophies etc! just expressing how I felt about this guy! Generally not a nice person!â
