Gill, 19, first joined Barça in 2018 and quickly progressed through the club's La Masia academy, signing his first professional deal with the club in 2022.

Those terms expired in June, but Gill has continued to train with Barça this summer as he recovers from an injury.

Barça have now decided to prolong his contract by an additional year, with the Denver-born player set to form part of Juliano Belletti's Barça Atlétic side, who play in the fourth tier of Spanish football.

Gill, who can play in midfield or at full-back, has represented the U.S. at youth level but has not been regularly involved since the U17s due to a series of injuries.

Last season, he was one of three American players in and around Barça's reserve side, along with goalkeeper Diego Kochen and midfielder Pedro Soma.
