Inter Milan chief Ernesto Paolillo has hit out at Roma fans over their barracking of Mario Balotelli during Sunday's 3-3 draw.
Paolillo said: "Yesterday, whenever Balotelli was near the ball, the Roma fans in unison would react, which some would interpret as racist singing.
"Balotelli stuck out his tongue in defiance. Of course, I've told him to learn to not react. But I can understand his reaction.
"Balotelli has much to learn. What happened yesterday could serve as a lesson."
