Arrogant, vain, self centred, no manners and ignorant: Former Manchester City kit man slams axed Roberto Mancini A former Manchester City employee stands accused of kicking a man when he was down after laying into Roberto Mancini last night, just moments after it was confirmed the Italian had been sacked. Stephen Aziz, a former kit man at the club, slammed Mancini on Twitter, labelling him arrogant, vain, self centred, and ignorant. Aziz also claimed that many staff and players at the club will be happy to see the back of the former Inter Milan manager. Aziz is understood to have been released from his role at the Etihad in May last year and has since taken up a role as assistant kit man at Sunderland. Yet it would appear he still harbours strong feelings about this season's defeated FA Cup finalists. "Some city (sic) fans unhappy about the sacking most managers would have won trophys (sic) with this team a lot of staff and players will be happy!!," Aziz tweeted last night. Aziz went on: "Arrogant, vein (sic), self centred no manners ignorant just some of Mancini's daily traits really made going to work a grind!! #karma Not my style to come in 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' Mcfc on the other hand what a club to work for some great players and staff nice down to earth ppl loved working there!!! #MCFC not saying he didn't do well to win trophy's (sic) etc! just expressing how I felt about this guy! Generally not a nice person! Didn't want to upset anyone felt the time was right to express how I feel about Mancini.... Don't burn your bridges maybe... but I just didn't like the guy and at the end of the day he's only human! just because he's a figure doesn't mean he can't be criticised The tweets have since been deleted from Aziz's account on which his profile picture shows him celebrating City's Premier League triumph with Adam Johnson. Mancini was sacked last night after City's failure to win any silverware this season, with Malaga coach Manuel Pellegrini expected to replace him. Despite Aziz's view, many City fans, who notably chanted the name of Mancini throughout their FA Cup final defeat to Wigan, are disappointed at last night's announcement. Kevin Parker, general secretary of the Manchester City Supporters Club, said: "After the weekend I think we were all expecting it to happen but I think we are all a bit disappointed it happened yesterday of all days - the anniversary of when we won the Premier League. All those fantastic memories we have of May 13, 2012 - that date is a special date for City fans and that's been a little bit tarnished. We're definitely all disappointed. A statement from the club said that Mancini had been relieved of his duties for failing to achieve the season's "stated targets." Parker said: "It is unbelievable. The club have said the targets set haven't been met, but finishing second in the Premier League and losing finalists in the FA Cup would suggest those targets might have been unachievable. Does that mean we had to win the Premier League and win the FA Cup?
