AC Milan have not received a bid for goalkeeper Gianluigi Donnarumma from Manchester United and will not consider selling the 16-year-old, general manager Adriano Galliani has said.
Italy's Mediaset Premium reported this week that United were preparing a €40 million (£30m) summer offer for Donnarumma.
However, Galliani said the keeper will not be leaving the San Siro under any circumstances.
"He is and he will remain Milan's goalkeeper," the 71-year-old told RAI television. "We've not received any offers for him and if any were to come in, we would turn them down anyway."
In October, Donnarumma, who turns 17 next month, became the youngest goalkeeper ever to start a match in Italy's top division and has gone on to make 11 appearances in Serie A.
He has been tipped as a star of the future by Juventus and Italy star Gianluigi Buffon.
Galliani also said that Stephan El Shaarawy could return to the club if Luiz Adriano's transfer to China goes through, while Alessio Cerci may join Genoa.
