AC Milan general manager Adriano Galliani has dismissed claims Manchester United will launch an extraordinary £30m bid for 16-year-old goalkeeper Gianluigi Donnarumma. The teenage shot stopper has enjoyed a remarkable rise to prominence this season despite his tender years, displacing Diego Lopez to become the Rossoneri's first choice option in goal.

According to Mediaset Premium, the United hierarchy have identified the Italian as their long-term replacement for David de Gea, who was on the brink of signing for Real Madrid during the summer transfer window.

They also suggest Milan will consider bringing in Paris Saint-Germain goalkeeper Salvatore Sirigu, either in January or in June, to replace the youngster.

But Galliani has denied the club have received an offer from Old Trafford, adding any that do come their way will be automatically rejected.

"He is and he will remain Milan's goalkeeper," Galliaini rold RAI, ESPN report. "We have not received any offers for him and if any were to come in, we would turn them down anyway."

Donnarumma has already been tipped by Italy legend Gianluigi Buffon to become an integral player for the Azzurri, having become the youngest ever goalkeeper to start in a Serie A match.

The teenager has also been described as "a piece of Italian artwork" by his agent Mino Raiola, who claims his client is already worth £120m.

"I would compare him to a [piece by Italian artist Amadeo] Modigliani," Raiola said in November. "He is worth €170m. He has a great future. He is an extraordinary kid and everyone loves him. He's already a little champion but he can become a great one."
