The 20-year-old Italian has been no stranger to controversy since joining from Inter Milan for £24m in the summer and was dogged by disciplinary problems while with the European champions.
"Balotelli went to City and will remain there for several years. It is impossible for him to join Milan in June, almost impossible," Mino Raiola told Telelombardia.
"He went to City with a strong commitment to Mancini and he should thank him for his confidence. But, the fate of Mario doesn't depend on Mancini."
