Vincenzo Montella says AC Milan are pulling out all the stops in a bid to convince Gianluigi Donnarumma to sign a new contract with the club.
Donnarumma, 18, is attracting attention from many of Europe's top clubs as he enters into the final year of his current contract with the Rossoneri, but Montella is keen to have him at his disposal next season and says Milan's ambitious new owners are doing all they can to satisfy him.
"The club are making enormous efforts to ensure his outstanding quality is recognised," Montella told Mediaset. "I like him like a son, but now he needs to make a decision and realise what he wants to do as a grown up.
"But he must do this with the utmost serenity because the club are doing all they can to keep hold of him."
Donnarumma, who became the youngest goalkeeper to debut for the senior Italy team aged 17 last Sepetember, is still on youth terms with Milan and therefore stands to gain significantly from signing his first professional contract.
However, he is likely to be able to earn more than the Rossoneri can offer him at any of the top European clubs currently being linked with a move for him, including Manchester United and Manchester City, and his agent Mino Raiola has repeatedly said he first wants to see what the Italian club's new owners' true intentions are.
Milan secured a place in the third qualifying round of the Europa League at the weekend and could make a return to European football for the first time in four seasons next term, while the imminent signing of Mateo Musacchio from Villarreal is already an indication of the club's new Chinese owners' intent.
Those could be arguments to convince Donnarumma that he has a bright future to look forward to in Milan, who are also being linked with a move for Lazio's Naby Keita and Alvaro Morata of Real Madrid.
"There are a lot of Keitas in the world and the one at Lazio is a very interesting player, but every time we talk about him, it just pushes his value up, even more so when you consider [Claudio] Lotito [is Lazio's president]," Montella said, while his club's general manager Marco Fassone and sporting director Massimiliano Mirabelli were spotted in Rome on Monday.
