Sunderland 2025 summer transfers: Every confirmed signing and sale for Regis Le Bris' side

Sunderland secured promotion back to the Premier League via the Championship playoffs in 2024-25, and as they embark on their first top-flight campaign following eight years away, they have invested heavily in the squad.

The Black Cats' total outlay exceeded £150m, but arguably their best signing - Granit Xhaka from Bayer Leverkusen - cost just £13m.

The former Arsenal captain has been a standout performer for Regis Le Bris's side in the opening weeks of the season, as Sunderland picked up six points from a possible nine prior to the September international break, including a marquee 3-0 thrashing of West Ham United on matchday one.

In terms of overall fee, Habib Diarra was the club's most expensive arrival, with the midfielder costing in the region of £30m when he made the switch from Strasbourg.

With the window now shut, the Black cats have brought in 14 new faces, though they did lose striker Marc Guiu as he was recalled from his loan by parent club Chelsea on deadline day following an injury to Liam Delap.

In his place, the promoted team signed striker Brian Brobbey from Ajax in a show of intent as they seek to be the first side from the Championship to avoid being relegated from the Premier League since 2022-23. 

Here, Sports Mole tracks every incoming and outgoing during Sunderland's 2025 summer transfer window.
