Will chelsea really struggle during the ACN?

hell yes, they have so many players out.... Essien, Drogba, Mikel and Kalou out in ACN. And Bosingwa and Anelka out with injury. So i Believe they are screwed. They dont have enough depth to beat Birmingham and Sunderland. But theyre defense is really good and noone in defense is out to the ACN so I believe that they can cleansheet but they wont be able to score with players such as Sturridge as lone striker
