Ruben Loftus-Cheek's stoppage-time winner sealed a dramatic, late turnaround for Chelsea at Cardiff City.
Victor Camarasa's classy second-half strike had looked set to secure a precious victory for Cardiff, before headers by Cesar Azpilicueta and Loftus-Cheek saved Maurizio Sarri's side.
In a goalless first-half, Pedro curled a shot over and Willian went close with a free-kick for Chelsea, while Josh Murphy flashed an angled shot narrowly wide at the other end.
A minute after half-time, Harry Arter crossed low and Camarasa calmly clipped in a first-time finish.
Eden Hazard's introduction from the bench bolstered Chelsea's attack and Azpilicueta's late header from Marcos Alonso's 84th-minute flick-on brought them level.
In the first minute of added time Loftus-Cheek appeared at the far post to plant a firm header from Willian's centre past Neil Etheridge.
Chelsea stay sixth but move level with Arsenal on 60 points. Neil Warnock's men remain 18th on 28 points, five behind 17th-placed Burnley.
