Their formation is most probably going to be 3-4-3 like udinese's coach stated. So, I see it very logical to also play 3-4-3/3-5-2 since we have several injuries. I don't think their back-line is any better than ours(not that ours is superior to them) but they're in no way better.
And about their front three, indeed they look strong and fast in the front, but we also got our weapons up there, Nedved, Dp, Trezeguet, Iaquinta.
Plus, we're playing home, they're going to be the under-dogs, not us. If we uses our chances well, If Ale and Pavel are fit, I doubt them holding us.
