Paolillo says the youngster should apologise immediately for his behaviour at the end of the victory over Barcelona.
“The club and the President have already commented on what happened, declaring it a gesture that should absolutely be condemned,” commented Paolillo on 7Gold television.
“All the other issues will be discussed with the player behind closed doors.
“We have all been 18, the age of rebellion, but I hope Balotelli can soon reach the age where he realises you cannot behave this way.
“You apologise straight away and not after a while. I hope his apology will be in the form of great goals for Inter in the next few games that can bring him closer to fans and teammates.
“It would be the best way for him to say sorry.”
