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.

If the deal is completed, the Ivory Coast international will become Sunderland’s sixth signing of the summer transfer window.
