AC Milan's incoming Chinese owners see Gianluigi Donnarumma's new contract as a priority.

The 17 year-old is firmly established as Milan's No1 and management recognise the need to secure him to a long-term deal as soon as possible.

Donnarumma's agent, Mino Raiola, has warned of interest from abroad, where Real Madrid, Chelsea and Manchester United have all been mentioned as destinations.

Gazzetta dello Sport says Milan's new GM Marco Fassone is working on a contract proposal for the youngster.

In Italy, Donnarumma cannot sign a deal for longer than three years until he turns 18 - which will happen in February.
