Mbaye, who just turned age 16, will immediately join the youth setup of the Rossoneri.
AC Milan have reportedly signed U.S. youth international Astin Mbaye from the New York Red Bulls academy.
The 16-year-old has an EU passport, allowing him to leave at that age for the Italian. Several other teams in Europe were chasing his signature, while RBNY was in talks over a pro contract, but the Rossoneri have secured his services. Current U.S. internationals Christian Pulisic and Yunus Musah both play for the Italian club.
Fabrizio Romano first reported the deal, while GIVEMESPORT confirmed it with additional details.
The RBNY academy has excelled in recent years, highlighted by the development of USMNT captain and Bournemouth star Tyler Adams, along with U.S. fullback John Tolkin, who plays for Bundesliga side Holstein Kiel.
The Eastern Conference MLS side also boast one of the most talented teenagers in all of MLS in Julian Hall, who is attracting interest from some of Europe’s top teams at age 16.
Mbaye, meanwhile, has been a mainstay with the U15 youth national team, representing his nation six times at the U15 level, including at the December 2023 UEFA Developmental Tournament, where he bagged a goal against Scotland. He recently earned his first call-up to the U16 national team.
The last American defender to play for the senior team of AC Milan was Oguchi Onyewu, who played for the Rossoneri from 2009-2011.
