But Eden Hazard, back from a three-game absence with a back problem, provided the striker's second with his first touch, sending over a free-kick which Morata expertly diverted into the net.
FW Willian, 6 - This was his 11th start in a row and while he generally looks more risky cutting in from the left flank, there was a noticeable lack of pop and imagination in his play against Palace's massed defensive ranks. While the conventional wisdom at the start of the season was that only Liverpool could challenge Manchester City for the title, Chelsea have showed they are genuine contenders. The Eagles are over-reliant on Zaha to get them out of trouble on most occasions, which is never a good thing.
However, Hazard is eternally grateful to his current club for everything they've done for him since his move from Lille six years ago, and he's loving playing under his new manager, Maurizio Sarri.
Trump Announces Return of U.S. Sanctions on Iran
The country's refiners imported around 10 million barrels, or about 1.4 million tonnes, of Iranian crude in October. An Iranian government spokesman says the country remains nonchalant about the sanctions being re-imposed.
Sarri has equalled the record for a manager going unbeaten at the start of his Premier League career.
Sarri has used just 19 different players in the Premier League this season - Wolves (17) are the only team to have fielded fewer - and several of the players on the fringes of Chelsea's squad have publicly expressed frustration with their lack of minutes.
"For now, I have to send to my players the message that only this match is important". Meanwhile, Crystal Palace were beaten by Championship side Middlesbrough in the same competition, their fifth consecutive game without a win.
Predicted Chelsea XI: Arrizabalaga; Azpilicueta, Rudiger, Luiz, Alonso; Jorginho; Kante, Barkley; Pedro, Morata, Willian.

January offers a chance for Chelsea to bolster their defensive options but Sarri, who has previously described the transfer market as "the refuge of the weak", is determined to find solutions on the training pitch.
The midfielder was rested in midweek against Derby with Mateo Kovacic starting so should be in line to start against Palace on Sunday.
Morata missed a hat-trick opportunity when played through by Hazard on the counter-attack in stoppage time.
Wednesday's scrappy win in the Frank Lampard Clásico is unlikely to stop Maurizio Sarri ringing the changes on Sunday, but the Italian will no doubt have been pleased enough with what he saw. We need to press in the opponents half.
