Former AC Milan goalkeeper Mario Ielpo is urging Gianluigi Donnarumma to stay.
The teenage keeper is in contract dispute with Milan and has been linked with several heavyweights, including Manchester United, Chelsea and Real Madrid.
But Ielpo says: "He seems to be a very serene and calm boy, but the problem is simple because he is a champion of his generation and he has to play in a great team.
"There are alternatives.
"What I can advise him is to renew his contract with AC Milan so that when he leaves, the club will profit economically."
