After their transfer window nightmare, Sunderland went on a nine-game winless run, ending when they defeated Derby County 4–1 at Pride Park. This was Coleman's final victory in charge of Sunderland; his final six games saw the Black Cats record three draws and three defeats. Relegation to League One was confirmed following a 2–1 defeat against Burton Albion at the Stadium of Light. His final game in charge was a 2–1 defeat to Fulham. On 29 April 2018, Coleman was dismissed shortly following the club's sale.
