Commanded his area with assurance and made a save whenever he was called upon, but Chelsea did not extend him anywhere near as much or as often as they should have. Made one good save to stop Hazard bringing the Blues level.
Repelled the vast majority of Chelsea's crosses with ease and Torres gave him little to contend with on the ground.
Would have expected a tougher afternoon against the league leaders but a typically uninspired performance from Torres spared him any real hardship.
Mostly succeeded in standing up Hazard rather than letting the Belgian surge past him and got forward whenever he could to try and support Puncheon.
Stood up well to the differing challenges posed by Hazard and Schurrle as they switched flanks, and made one vital sliding block to prevent the German opening the scoring from Azpilicueta's low cross.
Worked hard to press Chelsea's midfielders and prevent them getting into any kind of rhythm. Missed two excellent chances to finish off the Blues in the second half.
A powerful presence in midfield but also showed more subtlety than he is often given credit for, neatly slipping Puncheon in down the right in the first half.
Always so reliable in his use of the ball in midfield and got away with some questionable holding when defending set-pieces.
All enthusiasm and trickery, he caused Azpilicueta problems all afternoon, even if his final ball generally let him down. Clipped in the cross which Terry diverted beyond Cech.
Fulfilled his defensive duties diligently and doggedly - perhaps too doggedly at times, picking up a deserved booking in the first half. More of a goal threat after Palace had taken the lead, sliding one shot just wide of Cech's far post.
Chased lost causes as well as he usually does and provided a solid focal point for his team's most promising attacks with his strength and pace.
Debatable whether he should take a portion of the blame for Terry's own goal. Did not disgrace himself otherwise but beaten at the moment that really mattered.
His worst performances of the season. Troubled by Jerome more than anyone thought likely, could not inspire his team to produce a performance of the required intensity and directed a Bolasie cross past Cech to seal the defeat.
Tormented by Bolasie's pace, skill and direct running until Palace scored and his lack of crossing ability seriously hindered Chelsea's ability to create waves of pressure once they had gone behind.
Got forward once to provide a low cross which Schurrle was inches away from converting, but otherwise provided little in the way of attacking thrust and could not prevent Puncheon's influence growing as Chelsea pushed for an equaliser.
Picked up a knock early on when clattered by Bolasie and looked out of sorts until his withdrawal at the break, his only memorable contributions coming in the form of speculative shots which flew well over.
Made one excellent covering challenge to stop Bolasie racing through on goal and was not directly responsible for the goal.
His worst match in a Chelsea shirt. Not imposing enough in the tackle, wayward in his passing and could not stem the tide of Crystal Palace counterattacks in the closing stages.
Nowhere near his best. Slowed the play down too much and missed a huge chance when Oscar's shot found him unmarked in the box, firing the ball comfortably within the reach of Speroni.
Not as influential in a three-man midfield as expected and was sacrificed for Salah as Chelsea chased the game.
Delivered a performance of typical impotent nuisance, keeping the Crystal Palace defenders just about occupied without ever looking like scoring. Chelsea really, really need a striker.
Only an excellent sliding clearance from Ward stopped him opening the scoring from Azpilicueta's low cross in the first half, but overall he was a peripheral figure and was replaced by Ba with 20 minutes to go.
Combined well with Oscar on occasion but still looks to be adapting to English football.
Came on for Lampard at the break and provided some creative impetus with his intelligent movement, but could not make a decisive contribution.
Made no discernible impact when brought on for Schurrle on 70 minutes.
