1 win in 20+ years there tells its own story. In that time we've had seasons where we were better than them, where they had injuries, where (like tomorrow) we had a week's rest and they played 72 hours before the fixtures, etc.
It's very, very unlikely (but not impossible—it must change sometime) we beat them, but we have to have a go, which is something Moyes has refused to do too many times.
A draw is very much more attainable, but going there looking for a draw is too dangerous as they have the officials on their side and will get opportunities to nick a winner if they haven't put the game to bed.
Anyway, we have players capable of hurting them, so let's see how it goes.
Much worse teams have gone there and enjoyed multiple victories over the last decades, so there really is no excuse for our horrific results against them at Anfield.
