Brighton 2025 summer transfers: Every confirmed signing and sale for Fabian Hurzeler's side

Brighton and Hove Albion are gearing up for their ninth consecutive season as a Premier League club and will aim to finish in the top half of the table for the second year running after ending the previous campaign in eighth spot.

Fabian Hurzeler’s side narrowly missed out on European qualification and that has subsequently led to the departure of star forward Joao Pedro to Chelsea, while other key first-team players may also opt to seeks pastures new.

However, Brighton have been busy strengthening their squad this summer, with teenage starlet Charalampos Kostoulas the standout acquisition thus far from Olympiacos.

A total of five new players have arrived at the Amex Stadium, at the time of writing, and more fresh faces are expected to join the Seagulls as they endeavour to reach new heights in the 2025-26 season.
