Mancini's quotes from Sky Italia.
"Balotelli is not for sale," Mancini told Sky Sport Italia.
"Mario is a City player, he is loved by the fans and the management. He has been an important player for us.
"A player of his quality should think exclusively to his work and his family, he has talent and he cannot blow it as he is doing.
"Our paths may separate if I change team, but he will remain at City."
"I'm fine at City," said the Italian. "I work in a very serious club and in England it is easier to work. There is a project and we have done a great job in two years.
"I feel really good, but it is clear that I miss Italy because home is always missing."
Asked about the prospect of coaching the Italy national team, he added: "It is still early and [Cesare] Prandelli is doing well."
