I think so long as Suarez is fit, anything could happen for Liverpool. If he got a long time on the sidelines then I think it would be a test on par with RVP & Rooney's absence at United. Depends on how long, though.
We're alright without him - so long as Sturridge is fit! Sturridge scores just as often as Suarez does, although he's also had injury blights. Suarez seems relatively tough in comparison with Sturridge.
