Chelsea have completed the signing of Boca Juniors defender Aaron Anselmino in a £15.6m deal.
The 19-year-old has signed a seven-year contract at Stamford Bridge but will remain on loan at the Argentine club for the 2024-25 season as part of the agreement.
He made his debut for Boca in June 2023 and has made 10 appearances in total.
Anselmino signed a contract extension in January 2024 that tied him to the club until 2028.
Chelsea have been active in the transfer market this summer, recruiting Tosin Adarabioyo, Estevao Willian, Omari Kellyman, Filip Jorgensen, Marc Guiu and Kiernan Dewsbury-Hall.
