Italian was sacked by the club on Monday night after four years at the helm.
Sacked Manchester City manager Roberto Mancini has been labelled as “arrogant, vein, self centred and ignorant” by the club’s former kit man, reports the Daily Mirror.
The Italian was relieved of his duties as the City coach on Monday night after four years in charge at Eastlands, during which time the 48-year-old won both the 2011 FA Cup and the 2012 Premier League title for the very first time in the club’s history.
However, failure to follow up on those twin successes in this campaign, in which arch-rivals Manchester United have regained their top-flight title with some ease, has resulted in the one-time Fiorentina, Lazio and Inter Milan trainer losing his job.
And now City’s ex-kit man, Stephen Aziz, has taken to Twitter to lambast Mancini’s man-management style, writing: “Not my style to come in (sic) here and start to bad mouth someone but this guy was really a piece of work.
“Fans don’t get to see what really goes on and day 2 day running 2 years there seeing him every day was hard work getting a ‘good morning’.
“Some City fans unhappy about the sacking. Most managers would have won trophys (sic) with this team. A lot of staff and players will be happy!!
“Arrogant, vein (sic), self-centred, no manners, ignorant, just some of Mancini’s daily traits. Really made going into work a grind. #karma”
Aziz, who worked for City for two years before leaving the club to join Sunderland last summer, has since removed the tweets.
Mancini was in charge of City for 191 matches between 2009 and 2013, winning 191 of those contests and losing on just 40 occasions to give the ex-Italy international an impressive overall win percentage of 59.
