AC Milan hero Gianluca Zambrotta fears Mario Balotelli is already past his peak.

Zambrotta was commenting on Balotelli's performance after the 3-3 draw with Frosinone.

"He's putting in more effort than he did under Mihajlovic," the former full-back told Premium Sport. “Balotelli showed something extra in the last few games.

“Unfortunately his team is in a difficult moment. Obviously this is not the same Balotelli as the one who was decisive at the [2012] Euros."
