Chelsea 2025 summer transfers: Every confirmed signing and sale for Enzo Maresca's side

Chelsea's busy 2025 summer transfer finally came to an end on Monday night with Enzo Maresca likely to have been left satisfied with the make-up of his squad.

Although there was initially some frustration over the Blues hierarchy failing to sign a centre-back to replace the injured Levi Colwill, the Italian has a wide array of options at his disposal.

On deadline day, Chelsea were restricted to just the one addition, getting a loan deal over the line for Brighton & Hove Albion playmaker Facundo Buonanotte.

Facilitating exits became the priority for the majority of the day, Nicolas Jackson having finalised a loan switch with obligations to Bayern Munich and high-earner Ben Chilwell joining Strasbourg on a permanent basis.

A number of exiled players remain at the club, however, with it yet to be seen whether Chelsea can find a permanent or temporary home for the likes of Axel Disasi, Raheem Sterling and David Datro Fofana while other transfer windows remain open around Europe.

Here, Sports Mole rounds up every new signing and departure from Chelsea's 2025 summer transfer window.
