Ledley's expected to be fit and play and Woody's been practically injury free since he joined. If one or other was substituted, it would be more likely for the departing CB to be replaced by Bent and play 3-4-1-2 with Berbatov in the hole. Ramos has used that strategy a couple of times already, the thinking being that Hutton and Chimbonda are tall and quick enough to do the job respectably (Chimbo has been a CB before) whilst both Zokora and Huddlestone have both played CB before and can lend a hand if necessary.
Ramos seems to have devised a lot more alternative options for different scenarios than Jol who always seemed limited when adapting to different situations as the game went on.
I was joking man, you fanny
