Flashback to Sunderland's stunning Premier League comeback against Chelsea in May 2016.
Diego Costa opened the scoring before a bolt from the blue from Wahbi Khazri levelled the game, but a Nemanja Matic strike on the brink of half-time restored the visitors' advantage.
However, a rousing second period saw the Black Cats turn the tables as Fabio Borini and Jermain Defoe cemented a huge win on Wearside.
Watch the video above and recall a day to remember.
