Watch: Bonucci consoles Donnarumma after insults from AC Milan fans

AC Milan supporters whistled and jeered at Gianluigi Donnarumma before Wednesday's Coppa Italia clash against Hellas Verona, leading captain Leonardo Bonucci to console the 18-year-old in the dressing room.

Reports in Italy emerged in recent days suggesting Donnarumma's agent, Mino Raiola, is trying to cancel the goalkeeper's contract on the grounds he was bullied into signing it. Donnarumma put pen to paper on a five-year contract in the summer after declining the initial offer.

"Moral violence, €6 million per year and the signing of a parasite brother? Go now. Our patience is finished," read a banner from Milan's hardcore supporters, referring to Gianluigi's brother, Antonio, who arrived in the summer.

The Curva Sud, as the fans are known, stationed themselves right behind the younger Donnarumma at kick-off. The goalkeeper shook his head several times before starting the match.
