Manchester City boss Roberto Mancini admits the club “are not happy” at selling Mario Balotelli, who moved to AC Milan for £19m on Thursday.

The striker, who had scored 30 goals in 80 appearances for City, agreed a four-and-a-half-year deal with the Italian club.

Mancini says Balotelli was “an important player” for Man City, but when questioned on the sale Mancini admits “this is football”.
