Willian drives down the right and bullets a cross into the area, but McArthur clears for a corner. It's crossed into the area, but Ward and Tomkins are able to head away.

Pulisic close! Willian breaks on a counter and plays Pulisic through inside the area on the left. Pulisic displays brilliant feet to skip past two defenders before shooting into the body of Guaita from close range!

Yellow card! Zaha is booked for bringing down Willian outside the Palace area. Emerson and Willian step over the ball in a good crossing position...

Willian shoots! The winger hits a deflected effort which appears to be looping down into the top right corner of the net, but Guaita stands under it and holds! That was close!

Handball appeal! Pulisic miss-controls the ball in the area which pops up into the arm of Kelly, but there's not enough in it for a penalty.

Abraham close! The ball is crossed into the area from the right side and deflects into the path of Abraham! He hits the bouncing ball into the side-netting, but the assistant has his flag up for offside.
Half-time! There won't be time for the Chelsea corner as the referee calls an end to the half. Chelsea really did come so, so close at the end there. The score at half-time: Chelsea 0-0 Crystal Palace!
Best chance of the match! Reece James drives a low ball across the face of goal which Abraham just can't get a toe on! With Guaita out of the picture, it falls to Willian inside the 6-yard box who sees his effort deflected out for a corner!
GOAL! Abraham gives Chelsea the lead! What a fantastic team goal. Kovacic beats two men and plays Willian on the edge of the area. Willian then flicks it on to Abraham who slots into the bottom right corner with just the keeper to beat!
There's a break in play as James Tomkins is down with an issue. It's unclear whether he'll be okay to continue at this point, so we'll have to wait and see how he does.

Yellow card! McCarthy is booked for raising his studs against Kovacic, and Chelsea have a free-kick in a good shooting position. Willian and Emerson stand over the dead-ball...
Just over! Willian fires the free-kick towards the top-left corner with power but sees the effort fly over the crossbar! Good effort by the winger, but it never looked to be troubling the keeper.
