AC Milan have confirmed the signing of USA international midfielder Yunus Musah from Valencia.
The 20-year-old - who will wear the number 80 shirt - has penned a five-year deal with the Rossoneri until the summer of 2028 and is believed to have cost €20m (£17.3m).
Musah becomes Milan's eighth signing of the summer, following Ruben Loftus-Cheek, Christian Pulisic, Samuel Chukwueze, Tijjani Reijnders, Noah Okafor, Luka Romero and Marco Sportiello to San Siro.
A product of the Arsenal youth academy, Musah left the Gunners in 2019 without making a single first-team appearance, but he made a name for himself at Valencia with five goals and three assists from 108 matches.
The 2022-23 campaign saw Musah register two assists in 37 games, largely featuring as a central midfielder but also being deployed on both flanks and as a number 10 on occasion.
A 27-cap USA international, the New York-born lynchpin started all four of the Yanks' 2022 World Cup matches and has won two CONCACAF Nations League titles since his international debut in November 2020.
Musah could make his Milan debut in next Tuesday's friendly against local rivals Monza, before Stefano Pioli's side conclude their pre-season preparations against Tunisian outfit Etoile du Sahel on August 12.
