Former Man City manager Roberto Mancini believes Liverpool striker Mario Balotelli is "wasting" his professional career.
The pair worked together during Mancini's first spell at Inter and again at Man City, before Mancini was dismissed and Balotelli moved to AC Milan.
The Italian striker failed to live up to Milan's expctations and was offloaded to Liverpool last summer, where things have gone from bad to worse both on and off the field.
Speaking to Corriere della Sera Mancini, currently enjoying a second spell in charge of Inter, said:
Manchester City have announced that Assistant Manager David Platt has left the club.
They've issued the following statement.
"With regret Manchester City announce that David Platt has this afternoon left his role as Assistant Manager at the Club.
David was offered the opportunity to continue his work with us but has declined the invitation. He has decided to leave his role with his close friend Roberto Mancini.
David has made a significant contribution to the Club’s success since joining in 2010 and we wish him well with his career wherever that now takes him."
Malaga manager Manuel Pellegrini is currently the odds-on favourite to take over at Manchester City.
Jose Mourinho, widely reported to be in line for a return to Chelsea, is a 7-1 second favourite to get a move to Manchester, while current PSG boss Carlo Ancelotti is a 16-1 outsider.
Manchester City sacked Roberto Mancini exactly one year after they won the Premier League title thanks to a late Sergio Aguero goal.
Manchester City's assistant manager Brian Kidd will take charge of the remaining two fixtures of the season and the post-season tour of the United States, the club announced.
Manchester City fans have started to react on Twitter to the decision to sack manager Roberto Mancini:
Chairman Khaldoon Al Mubarak said: “Roberto’s record speaks for itself and he has the respect and gratitude of Sheikh Mansour, myself and the Board for all of his hard work and commitment over the last three and a half years.
"He has clearly also secured the love and respect of our fans. He has done as he promised and delivered silverware and success, breaking the Club’s 35-year trophy drought and securing the title in 2012.
"I would like to personally and publicly thank him for his dedication to the progress that he has overseen and for his support and continued friendship."
