Good news on the injury front - both David Luiz and Petr Cech are back in full training this week and therefore presumably available for the match against Sunderland on Saturday. Both players had been sidelined with knee problems, Cech having picked up an MCL issue shortly after keeping a clean sheet against Stoke City and David Luiz suffering from a tendinitis problem that's kept him out of action all summer since his return from the Copa America.
If fit, Cech is a certain starter - backup goalkeeper Henrique Hilario has been competent enough save for one rather odd mixup with centre back Branislav Ivanovic against Norwich City, but he's not the sort of guy who can win you matches like Cech can. David Luiz is a slightly different issue, since he hasn't played a competitive game since the end of last season and needs to work off the rust accumulated from sitting on Brazil's bench and then missing Chelsea's whole pre-season. Even the recent poor play from the centre back position is unlikely to see him start, but it wouldn't be a shock to see the 24-year-old on the substitute's bench come Saturday.
It's good to have both back in training, anyway. Chelsea are edging closer and closer to full strength (save the long-term absence of Michael Essien), and with Danny Sturridge available once again following a return from suspension, we'll have a much better idea of just how good this team is quite soon.
