AC Milan sporting director Massimiliano Mirabelli says the club signed Antonio Donnarumma for his football talents and not to keep his brother happy.
The club's massively-talented, first-choice stopper, Gianluigi, penned a four-year contract extension at the Serie A club this week after initially refusing to commit his future to the Rossoneri beyond his previous deal, which was set to expire in June 2018.
And soon after tying down the 18-year-old, the club announced the re-signing of his 27-year-old brother Antonio, also until 2021.
A former Milan player, Antonio could not force his way into the first team after stepping up from the youth ranks, and went out on loan to Piacenza and Gubbio before signing for Genoa.
A loan move to Bari was to follow ahead of signing for Asteras Tripolis for the 2016/17 season where he made 23 appearances.
He is expected to act as cover for his brother as well as Gabriel and Marco Storari.
Speaking after confirming the deal, Mirabelli said: "The first thing we had to do was to renew Gigio's contract, but I immediately had the idea of bringing in his brother Antonio too.
"The technical evaluation comes first and I think Antonio can be a 12th man for Milan.
"He is not a postage parcel like someone said. I'm sorry for him if certain things have been written. Vincenzo Montella also endorsed this signing.
"I know him well and I wanted to bring the family back together. I'm proud to present the Donnarumma pair."
And Antonio said: "I will be in the dressing room with my brother, which makes me very happy. It is a beautiful thing to be back at Milan."
