Mancini was sacked after three-and-a-half years as manager on Monday and his first-team coach David Platt left the following day.
Among those also to have departed are defensive specialist Angelo Gregucci and reserve team boss Attilio Lombardo, the former Sampdoria and Crystal Palace player.
A City statement read: "Manchester City can confirm that Ivan Carminati, Fausto Salsano, Massimo Battara, Angelo Gregucci and Attilio Lombardo have left their respective roles at the football club.
"We thank them for their contribution to Manchester City since their arrival and wish them well with their future careers."
