Everton 3-1 Chelsea: 5 Talking Points & Tactical Analysis | Premier League 2019-20

#3 Chelsea's defensive calamities rise to the surface, again

Dominic Calvert-Lewin robbed Zouma and Christensen off the ball way too easily

Against a side playing out of their skin in front of a bouncing home crowd, all Chelsea had to do with their lion's share of possession on the defensive front was stick to their basics, stay close and tight to their markers and play on the line.

However, the center-halves made an absolute mishmash of what should have been a simple clearance. Christensen initially mistimed him jump and got almost nothing on the ball with his head, before Zouma failed to sort his feet out in his attempt to clear the loose ball.

Calvert-Lewin, known for his tenacity, fought hard to win it back and took the chance with both hands, slotting the ball past an onrushing Arrizabalaga. It's not the first time Chelsea's problems at the back have been outlined.

They commit such errors repeatedly, and on days when their forward line isn't firing on all cylinders, it puts more pressure on the likes of Mount and Abraham.
