Sunderland have confirmed the permanent signing of winger Simon Adingra from Brighton. The 23-year-old Ivory Coast international has moved for a fee of £21m plus add-ons and has signed a five-year deal at the Stadium of Light.

Adingra is a player that the Black Cats have long-standing interest in, with the club being linked to the winger in January. It was reported that Sunderland attempted to bring Adingra to Wearside in a potential swap deal that would have resulted in Tommy Watson moving the other way.
