Man United target Gianluigi Donnarumma under Liverpool radar

Liverpool have reportedly joined the race to sign Manchester United target Gianluigi Donnarumma from AC Milan.

The 16-year-old teenager is also being closely monitored by the Premier League champions Chelsea, and is also on the radar of Spanish champions Barcelona as well as Ajax.

Despite at this age, the shot-stopper has already managed to leapfrog Diego Lopez between the sticks at Italian football and has been regular for the Serie A outfit.

AC Milan president Silvio Berlusconi has already insisted that Donnarumma is not available for sale no matter how much was offered and will be a key player of the squad for the next 20 years.

“Donnarumma is 16 years old, he is admired by all and he won’t leave Milan, whatever offer might come in,” he told Premium Sport.

“He will be the Milan goalkeeper for the next 20 years. He is a good lad, very strong physically, mentally and in terms of his character.”

The Italian is currently under contract at the San Siro until 2018 and has made 17 appearances in the league this season so far.
