Injuries to key players has made the Chelsea defence basically pick itself.
Chelsea will be without their captain once again, as John Terry will reportedly be out for at least another four weeks.
Chelsea's other defensive injury comes in the form of Jose Bosingwa, who himself got injured within the first 10 minutes of the first leg against Napoli.
This may be a blessing in disguise, as it does not give Andre Villas-Boas an opportunity to play him.
When I read the team sheet for the away leg at Napoli, and saw Bosingwa in place of Ashley Cole, I nearly spat out my beer.
RB - Branislav Ivanovic: Ivanovic is the obvious choice for right-back in a game of this magnitude. He would be the best candidate for this position even if Bosingwa had been fit.
His only other competition would come in the form of Paulo Ferreira, but Ivanovic is a more solid defender and has proven he can be an aerial threat from set-pieces.
CB - David Luiz & Gary Cahill: With John Terry out, there are no other options but for the new partnership to play together again.
If they perform like they did in the victory against Bolton, we have nothing to worry about. Obviously, Napoli will provide a tougher test, but for the first time for a while, the Chelsea defence looked composed and confident.
Chelsea need a clean sheet, but they also need goals, and both Luiz and Cahill have goals in them, and if Luiz can do some of his famous forward runs, he could cause the Napoli defence some problems.
LB - Ashley Cole: Chelsea's result could be influenced greatly by the performance of Ashley Cole. There is no doubt that on a good day, Cole is one of the best full-backs on the planet.
He will need to put in a consistent defensive performance, but it would be good to see him back doing his overlapping runs, and sending in some dangerous crosses and causing Napoli's defence some problems.
