Fans throw fake money at Donnarumma after he refuses contract extension

The 18-year-old left Milan in a state of shock after deciding not to extend his contract with the club.

Milan chief executive Marco Fassone denied Raiola's claims. "It could've been done without damaging the club, but by leaving like this, they have cost Milan €100m".

The teenager's agent Mino Raiola said, "The environment was too hostile and we made a decision that we didn't want to make".

Conti has been widely linked with a transfer to Milan this summer, as new owner Yonghong Li begins his tenure with a superb batch of player recruitment. Everyone is free to do what he thinks is best for him.

"I was wrong not to immediately stop this infernal machine - with that pounding we could not say yes", added Raiola. It was nothing to do with money.

Real Madrid are also believed to be interested in the 18-year-old, who has already made 72 appearances for Milan.

"Now there is a genuine risk he could miss a year".

Italian media said the supporters, who also chanted insults at the Italy global and displayed a banner reading "Dollarumma", were members of a Polish-based Milan fan club.

Despite being away on global duty with Italy U21s at the European Championship in Poland, a local Milan fan club ensured that he couldn't escape from the criticism.

The statement goes on to recognise the hard position Donnarumma has been put in, and even suggests there may be a future for him at the club should he change his mind.

As Giocondo Martorelli, the scout who first discovered Donnarumma, revealed yesterday, the player was snatched by Milan from under the noses of Inter when he was 14 for €250,000 (Dh1m). "However, we can not run any risks, so we need to seek out another goalkeeper".

"It is becoming increasingly hard for clubs to handle these situations".

As Donnarumma eyes a move to one of any several top clubs (including possibly Juventus), Milan will have to reckon with its wounded ego, let go of its pretension, and get to work building another top squad.
