Gianluigi Donnarumma is reportedly edging closer to agreeing a new deal with AC Milan, to be signed upon the date of his 18th birthday.

Donnarumma was a huge surprise in Serie A last season. At a young age he was able to earn his spot as Milan's first choice goalkeeper. Being one of the most talented gradutates of club's academy, he has the potential to defend the club’s colors for another two decades in goal, much like his hero - Gianluigi Buffon - has for Juventus.

Donnarumma's agent Mino Raiola will arrive Italy soon in order to discuss with Milan's management the terms of extension. However, the signing of the contract will not  happen until Donnarumma turns 18 next February. The reason behind this is due to the legal limits of an underage players contracts. They can only agree terms with club right now, yet once the player becomes an adult he can put pen to paper.

Currently Donnaruma’s is under contract with AC Milan until 2018, earning around 250,000 Euros per year. Raiola is reportedly aiming to extend the contract for five more years, with a raise in salary up to one million Euros per year.

The new Buffon?

It is been widely thought that the talent of young Gigi is quite similar to the legendary Italian goalkeeper Buffon. This is because their characteristics are quite similar, with huge leadership skills at such a young age. Vincenzo Montella is likely to rely on Donnarumma on goal for next season, as he bids to continue his progression.

Donnarumma made his debut in a 2-1 win against Sassuolo in October last year, the youngest player ever to be in a Serie A starting eleven at the age of 16 years and 8 months. As of now, he's represented Milan on 30 occasions, keeping 10 clean sheets.
