Gianluigi Donnarumma on Chelsea radar

Chelsea will reportedly launch a bid for AC Milan youngster Gianluigi Donnarumma, should Thibaut Courtois leave the club this summer.

Belgian international Courtois is said to be eyeing a potential move to Real Madrid after his side's failure to compete for the league title this term.

According to The Mail, the Blues have earmarked 17-year-old Donnarumma as their priority target for the summer following speculation surrounding their number one shot-stopper.

It is added that the West London giants are likely to face competition with league rivals Manchester City and Manchester United also said to be tracking the youngster's progress.

Donnarumma made his debut for the Rossoneri at a feeble age of 16, displacing experienced shot-stopper Diego Lopez.
