Donnarumma has said he will not be extending his contract, sparking an angry reaction from some Milan fans to both the player and his agent Mino Raiola.

After the news was announced, fans at the European Under-21 Championship threw fake dollar bills at the Italy keeper during the game against Denmark.

Montella held talks with Donnarumma's parents, and the player's father, Alfonso, told La Gazzetta dello Sport he believed the situation would calm down.

"I hope that all the massive media interest in this ends soon," he said.

"We parents are not influencing Gigio's decision in the slightest -- we just hope he gets what is best for him and what makes him happy."

He added that he had appreciated Montella's visit "because they [Milan] know what we are going through in a situation like this."

Some reports have said Donnarumma is reconsidering his options following the uproar caused by his decision not to sign a new deal.
