Agent Mino Raiola has revealed that in-demand AC Milan youngster Gianluigi Donnarumma could be on his way out of the club next summer.

The 17-year-old has taken Serie A by storm since being handed his debut at the age of just 16 in October last year, earning comparisons to goalkeeping great Gianluigi Buffon.

Reports this week suggested that Donnarumma, who replaced Buffon in the second half of Italy's goalless draw with Germany on Tuesday evening, would turn down any advances from elsewhere to stick with boyhood club Milan.

Raiola admits that nothing can be ruled out at this point, with Real Madrid, Juventus and Chelsea all reportedly circling, despite Donnarumma still having just short of two years left to run on his current deal.

"I can't exclude anything really," he told Corriere della Sera. "I can't even exclude that I'll be the next president of Italy and I can't even exclude that Donnarumma will play somewhere else one day.

"This guy is like a Modigliani, he's the combined Pele and Maradona of goalkeepers. There are unlimited possibilities for him in the transfer market."

Raiola also represents superstar midfielder Paul Pogba, and was paid £24m to broker his move from Juventus to Manchester United during the summer.
