A second-half strike from N'Golo Kante was enough for Chelsea to beat Crystal Palace 1-0 in the Premier League and send them five points clear of fifth-placed Arsenal
Chelsea had a goal disallowed for offside and twice hit the post in the first half at Selhurst Park, but scored the winner five minutes into the second period when Kante (50) rolled the ball past Vicente Guaita
Crystal Palace rallied towards the end of the game, with Connor Wickham almost poking home in the 89th minute, but they could not find an equaliser
Chelsea now have 43 points on the board - five ahead of Arsenal in fifth - while Crystal Palace remain in 14th with 19 points
Chelsea had their first chance of the game in the 14th minute
 Willian curled a free-kick into the area, which Antonio Rudiger met with a free header, but it looped into the arms of Eagles 'keeper Guaita
 Not long after, Kante tried his luck from the top of the box, but it just whistled past the far post
The visitors had the ball in the back of the net just before the half-hour mark, but Olivier Giroud was flagged for offside in a marginal call
 Jorginho pinged the ball over the top for the striker, but as he slotted home on the angle, the flag was raised and the goal ruled out
Willian went close with another free-kick in the 35th minute
 His curling effort deflected off the crossbar before going wide, although a corner was given - to the dismay of the home fans - as Guaita did not touch the ball as he attempted to make a stretching save
 From the corner, Willian tested Guaita, who did push it away this time, before Ross Barkley put a header onto the crossbar from a second delivery
Chelsea did find the net five minutes into the second half
 David Luiz pinged a ball over the top for Kante, who got behind Patrick van Aanholt to collect before sending the ball rolling past Guaita, with the Palace goalkeeper getting a fingertip to the ball but not enough to keep it out
Giroud had the ball in the net for a second time in the 74th minute, but he was once again penalised for offside in another tight call
 Willian played him through and he hammered the ball home, but the linesman had his flag up and it was ruled out
 Giroud got his foot caught under the body of James Tomkins as he struck and injured his ankle, which resulted in him being replaced Alvaro Morata not long after
Crystal Palace looked the most threatening in the final 10 minutes and could have snatched a late equaliser in the 89th minute
 Luka Milivojevic floated a free-kick into the area, which was headed down for Wickham by Tomkins
 He controlled with his chest despite some tight marking from Rudiger and managed to get a toe to the ball but sent it just over the crossbar from close range
"I thought we worked as hard as we could work and we were playing a very good team who made it difficult for us to disturb their passing rhythm
 I don't know if we could have done much more in terms of our approach to the game
 We played against a very good side and they were much better than we were
""I like that we were in full control of the match for 85 minutes
 We moved the ball very well and fast, especially in the second half
"I think we need continuity, in the results and the performances
 We need continuity in motivation and, as a consequence, in determination on the pitch, because in the last months we had some difficulties to find continuity
"Although it was far from a vintage performance from Chelsea, Jorginho continues to show his importance to the side
 He played some world-class passes, especially in the first half, and had the most passes of any players on the pitch
With Kante going forward more often - and scoring - he pulled the strings in the middle of the park and did well to limit Crystal Palace's quick attacking players throughout the game
Crystal Palace's next game will be on Wednesday January 2 when they travel to Wolves in the Premier League
 Chelsea will host Southampton on the same evening
