Jorginho (on for Gilmour, 80') - 6: Italian's passing helped Chelsea regain a measure of control. Reuters
CRYSTAL PALACE RATINGS: Vicente Guaita - 6: Pulled off a fingertip save to deny Mount at the end. Reuters
Joel Ward - 7, combined well with his winger Zaha to cause Chelsea problems down the right. Reuters
Scott Dann - 6: Could have earned his side a point they deserved but saw his header crash against the post. Reuters
Gary Cahill - NA, limped off after suffering a bad injury chasing Willian in the buildup to Giroud opener. His season looks to be over. EPA
Patrick van Aanholt - 9: The Dutchman was Palace's best defender and attacker and gave James a torrid time all evening. EPA
Cheikhou Kouyate - 7: Seemed confused as to whether he was meant to track Mount or pressure Gilmour in the first half. Grew into the game in the second. Reuters
James McArthur - 7: Presented with a chance to embarrass Kepa early doors but fluffed his lines from distance. A tireless worker in midfield. AFP
Luka Milivojevic - 7: The Serb destroyer loves nothing more than getting physical. Tired badly at the end though to the point he could barely jog. AFP
Jordan Ayew - 6: Good linkup with Van Aanholt and always looking to drive at James. EPA
Wilfried Zaha - 8: Palace's star man hasn't produced the heights of last year, but his first-half effort was a scorcher. Tormented Chelsea's full-backs in the second half.
Christian Benteke - 8: The big Belgian scored his first league goal at Selhurst Park in over two years. Could have levelled at 3-3 but took too long on the ball. General hold-up play was solid throughout. Reuters
SUBS: Mamadou Sakho (on for Cahill, 8') - 6: Probably played more minutes than he was anticipating and struggled in his battle with Giroud. EPA
SUBS: McCarthy (on for McArthur) - NA; Andros Townsend (on for Ayew) - NA; Max Meyer (on for Milivojevic) - NA
CHELSEA RATINGS: Kepa Arrizabalaga - 5, The Spaniard has the lowest save percentage in the Premier League, and there was little he could do to stop Zaha's thunderbolt, but just isn't a goalkeeper who inspires confidence. AFP
Reece James - 6: Given a stern test by Palace's marauders. Came off largely second best. Reuters
Andreas Christensen - 5: Switched off at the end which almost allowed Benteke to level and was bullied throughout by the Belgian. Reuters
Kurt Zouma - 8: Should have scored with a header in the first half and produced a game-clinching tackle at the death to deny Benteke. Reuters
Cesar Azpilicueta - 7: Mr Dependable again. Reuters
Billy Gilmour - 6: Tracked back well but Chelsea needed Jorginho's control and influence to see out the game. Reuters
Mason Mount - 7: Showed some fine footwork in the final third in the opening 45 minutes. Reuters
Ross Barkley - 6: midfielder's passing was well down on the levels against Watford. AFP
Willian - 7: Brazilian had little joy out wide against Van Aanholt but plenty of it drifting in field to generally make a nuisance of himself. EPA
Christian Pulisic - 7: A tale of two halves for the American - electric in the first and anonymous in the second. EPA
Olivier Giroud - 7: Showed some velvet touches at the spear of Chelsea's attack and was well worth his goal after Chelsea played on with Cahill stricken. Reuters
SUBS: Tammy Abraham (on for Giroud, 65') - 6: Took his goal really well to end a 10-game goal drought. Completely shanked a later attempt though. Reuters
Ruben Loftus-Cheek (on for Barkley, 65') - 7: Sumptuous pass to set up Abraham for what proved to be the winner. Reuters
