What's with the defeatist attitude from people? Sure, United are an opponent that should be respected, but not feared. We have enough quality to win. Of course, we can lose too, but why are people "scared"?
Yes, we can play better than we have, but we haven't been poor by any stretch of the imagination, except the game on Wednesday. Yes, United are on a good run, but many of their performances have left quite a bit to be desired. Struggled at home v Boro, and were rather mediocre v Hull in the cup too. So I'd say in terms of form, the teams are evenly matched right now.
Having Henderson and Coutinho back is a huge boost, both in terms of quality and in terms of a boost mentally for the players. Too bad Matip won't start, but Henderson should do a better job of shielding Lovren/Klavan than Lucas did v Southampton (how he got an 8 from the Echo is a mystery).
Klopp is 3 2 0 v the top teams, and we usually raise our game on big occasions.
