Chelsea FC have confirmed the signing of Argentina international Valentin Barco from RC Strasbourg.
The 21-year-old midfielder has signed a contract until 2033 and will join up with head coach Xabi Alonso and the squad later in pre-season.
Barco started his career at Boca Juniors, making his professional debut at 16. He won multiple titles with Boca before moving to Brighton & Hove Albion in 2024.
During his time in England he had loan spells at Sevilla and Strasbourg. He made his move to Strasbourg permanent after the 2024/25 season, where he helped the club qualify for European football.
In 43 appearances across all competitions last season, Barco contributed 12 goals. His club form earned him a place in Argentina’s squad for the 2026 FIFA World Cup. He has five senior caps for Argentina.
“Chelsea FC is pleased to confirm the signing of Argentinian international Valentin Barco from RC Strasbourg,” the club said.
Barco becomes Chelsea’s latest addition ahead of the 2026/27 campaign.
