You should be. No Gerrard, Johnson, Aurelio, Riera, Skrtel and Agger.
Its going to be tough going against a Lyon side that has done very well in the CL up till now.
Lyon have their own injury problems though, they have only one fit centerback available(Although that has been the case for over a month now). Toulalan is forced to play as a make shift centerback. His positioning as a defender leaves a lot to be desired, so Torres might just take advantage of their weakness in that department.
