Billy Gilmour has officially transferred to Napoli from Brighton & Hove Albion for an initial fee of £12 million, plus £4 million in add-ons, signing a five-year contract that will last until 2029. The move follows a successful medical, despite initial concerns after teammate Matt O'Riley sustained a serious injury, which threatened the deal. Gilmour, who has been a key player for Brighton since joining from Chelsea in 2022, will now join fellow Scotland international Scott McTominay at Napoli. The midfielder's departure marks the end of a two-year stint at Brighton, where he made 60 appearances. Brighton's technical director expressed gratitude for Gilmour's contributions to the club while acknowledging the player's desire for a new challenge in Italy. This transfer continues Napoli's busy summer window, which also saw the arrivals of Romelu Lukaku and McTominay, as they look to strengthen their squad under Antonio Conte.
