Former Livorno coach Nando Orsi admits Mario Balotelli's success with AC Milan has surprised him.

Orsi says his form hasn't taken him aback, but the attitude of the striker has been a pleasant development.

"He's back where he always wanted to play: in Italy and AC Milan," said Orsi.

"Apart from the performance, which I did not wonder about, the positive attitude has amazed me: he is doing very well from many points of view."
