Football agent Mino Raiola has claimed that AC Milan goalkeeper Gianluigi Donnarumma is worth in the region of £119m.
The 16-year-old made Serie A history in October when he became the youngest goalkeeper to start a game in Italy's top flight.
His rise to prominence has led to reported interest from Europe's biggest clubs, with Manchester United and Chelsea said to be looking into the prospect of signing the youngster.
Raiola, who represents Donnarumma as well as Paul Pogba and Mario Balotelli, told Mediaset Premium: "I'd compare him to a [piece by Italian artist Amedeo] Modigliani.
"He's worth €170million (£119m) and has a great future. He's an extraordinary kid and everyone loves him. He's already a little champion but he can become a great one."
Donnarumma has played six games for the Rossoneri since breaking into the first team this season.
