Chelsea will easily win with a few sub players , because Genk has lost 4 central defenders due injury. They will have to place a midfielder (Toszer) in the central defence because they haven't got enough. Also because another central defender is not 100 % fit yet , but he is selected for the squad. I really see Chelsea winning 4-0 or even with bigger number. So the defence in central won't even be a B-team , but lower. And in the belgian league they aren't doing so well last weeks , a bit due the fact of all those injuries in defence. Drogba or Torres will have an easy night to pass the defence. The only player you have to be scared of in the attack is De Bruyne , but he just came back from injury and hasn't got his good form yet. I expect a very easy win for Chelsea , Chelsea should be ashamed if they don't win easily.
