There are few faster ways to derail a title challenge than key injuries, even in a squad as deep as Chelsea is in places, so it's always good news when there is no new injury news.
Jose reports no new injury concerns ahead of Schalke. He says Cech had a back problem in warm-up today but made the bench. #CFC— Chelsea FC (@chelseafc) November 22, 2014
Diego Costa appeared to suffer a blow to the head from an inadvertent Dawson elbow and Willian looked to have possibly picked up a knock early on in the first half, but neither suffered any lasting effects apparently. Petr Cech's back tweak could be a concern, but he probably won't be truly needed until the final game in the Champions League group stage and the League Cup quarterfinal against Derby County a few weeks from now. Back injuries do have a tendency to linger, but if he was fit enough for the bench today, it's probably not a huge deal.
A healthy squad is a happy squad. A healthy squad 8 points clear of Manchester City and at least 4 points clear of second place Southampton (depending on Monday's result) is a very happy squad. Hurray for very happy days!
