The future of Gianluigi Donnarumma at AC Milan is again in doubt.

The Corriere dello Sport reports the goalkeeper, 20, has rejected a new contract offer tabled by Milan.

The deal is worth €6m-a-year and the decision to turn it down is being driven by agent Mino Raiola.

Milan remain determined to secure Donnarumma to new terms, with a reluctance inside the club to cash in on the youngster.

Raiola and Donnarumma, meanwhile, are playing a dicey game given the last time they refused new terms offered by the Rossonero led to a major breakdown in the goalkeeper's relationship with the support.
