"Chelsea FC is pleased to confirm the signing of Argentinian international Valentin Barco from RC Strasbourg," the club said, adding that "the versatile midfielder has signed a contract until 2033 and will join up with manager Xabi Alonso and his new team mates later in pre-season" [1].
Barco is a versatile midfielder who can also operate as a left-back. He appeared between 54 and 58 times for Strasbourg, scoring 3 goals and creating 11 assists in all competitions [1, 2, 3, 4]. Previously, he joined Brighton from Boca Juniors in 2024 for a £7.9 million fee before moving to Strasbourg initially on loan and later permanently [5, 1].
Internationally, Barco has earned five caps for Argentina, scoring twice. He was part of the Argentina squad that finished runners-up to Spain in the 2026 World Cup final held in July 2026 [1, 2, 3, 4].
