#1 Gianluigi Donnarumma
Gianluigi Donnarumma is perhaps the best young keeper in the world. At the age of 16 years and 242 days, he made his debut in the Serie A in 2015, becoming the second youngest ever keeper to do so. Ever since then, he shot into more and more limelight. He made his debut for the Italian National team at the age of 17 years and 189 days, making him the youngest ever keeper to feature for Gli Azzurri.
Currently contracted to AC Milan till 2021, the club might be forced to sell the player in order to comply with FFP requirements after failing to qualify for the UEFA Champions League next season. His agent, Mino Raiola, is also the agent of United midfielder, Paul Pogba and the Dutchman can play a crucial role in facilitating a transfer of the 20-year-old to Old Trafford. However, it is rumoured that Milan have a £55 million request put upon the player and the club must cough up that money to get his signature this summer.
