Sunderland have moved out of the relegation zone after beating Chelsea 3-2, with the visitors seeing captain John Terry sent off.
It was Chelsea who took the lead on 14 minutes after Gary Cahill was lucky to see his pass deflect to Diego Costa, who made no mistake in firing the shot home from six yards out.
Sunderland levelled four minutes before half-time with an incredible strike from Wahbi Khazri, who volleyed home from range into the corner after Chelsea failed to clear their lines.
The Blues headed the ball to Khazri who had no right to score from his position, but he stunned the Stadium of Light when he did.
That lead didn’t last long as Chelsea went ahead for the second time three minutes into first-half stoppage time through Nemanja Matic, who coolly slotted the ball home underneath Vito Mannone from close range.
Sunderland came back after the break and scored twice in three minutes to turn the game around.
First, Fabio Borini scored against his former club to level proceedings on 67 minutes when his deflected effort from the edge of the box had enough on it to beat Thibaut Courtois.
Jermaine Defoe then sent the home fans wild when he netted on 70 minutes after he showed beautiful control from a cross and then struck home from around the penalty spot to cue wild celebrations.
It was a frantic finale and Sunderland were made to work, but in the end they were able to hold on for a big win, with Terry sent off for a second yellow card four minutes into stoppage time.
