Chelsea captain Cesar Azpilicueta says they must improve at both ends of the pitch after defeat at Everton.

The Blues lost 3-1 at Goodison Park and Azpilicueta says they weren't good enough inside both boxes.

He told chelseafc.com: "Defence is an area where we have to improve but we are not strong enough in both boxes right now.

"We are conceding a lot and when we arrive in the dangerous areas, we are not clinical enough to score our chances.

"It's a major problem because in football the key is to be clinical in both boxes and at the moment we are not strong enough in both of them so we have to work on that."
