RB Leipzig has completed a permanent transfer for Marc Guiu, prying the young Spanish forward away from Chelsea in a deal that includes a sell-on clause.
Guiu, born on January 4, 2006, arrived at Chelsea from Barcelona on July 1, 2024, for a reported fee of approximately €6 million. Chelsea had locked him into a contract running until 2030.
A Chelsea career that never launched
In August 2025, Chelsea loaned Guiu to Sunderland in hopes that regular Championship football would accelerate his development. That plan lasted roughly one month before Chelsea recalled him due to injury problems within their own squad.
Under new coach Xabi Alonso, Guiu failed to secure a squad number for the 2026-27 season, a fairly clear signal that he wasn’t part of the immediate plans.
