Chelsea: Three of their biggest problems this season

Defensive woes

Antonio Rudiger is still out with an injury

Chelsea are no longer the defensive force they used to be. There was a time when teams were just incapable of penetrating the Chelsea defense. However, in the past couple of seasons, Chelsea's defense has looked pretty clueless at times.

Despite being in control in many matches, the Blues has been caught off guard due to poor organization and strategy. Set-piece defending is one particular area where Chelsea are quite weak.

Last season, Chelsea got beaten on several corners and free-kicks. There were many incidences where Chelsea left players completely unmarked and ended up conceding a goal. Even this season against Leicester, Chelsea gave their lead away as they fell short against a decent header from Wilfred Ndidi.

Some of these struggles are justified due to David Luiz's sudden departure. Moreover, their senior-most center-back, Antonio Rudiger is also injured.

While the pairing of Andreas Christensen and Kurt Zouma looks strong on paper, their recent performances suggest otherwise. There seems to be a lack of communication among the two as there have been problems in organization.

As Chelsea look to get something out of this season, they have to improve their defense as they have been leaking goals at regular intervals.

Can Andreas Christensen step up to the challenge?
