Gill, 16, first joined Barca’s La Masia academy in 2018 and has advanced through the youth teams over the last four campaigns, now playing for the under-16 side.
The midfielder will be promoted to the U19 set up next season, along with U.S goalkeeper Diego Kochen, who also recently penned new terms at Camp Nou.
Born in Denver, Gill has represented the U.S. at youth level and has been involved in training camps with the U17s this season.
Kochen, also 16, signed a three-year deal earlier in March to extend his stay at Barca, where he has already featured for the B team in a recent friendly fixture played behind closed doors.
