Well since no one is willing to start a thread for this important match I guess I'll try my luck as a match thread opener.
Like I said, very important match against a tricky side, regardless of their league position. They took points away from Everton, Manchester, Tottenham, Arsenal and Chelsea so they tend to play well with the bigger sides. Hopefully our strikers will be up to it like they were last time we played them and we'll have no problems.
The match is important because if we win we'll have a good distance away from our rivals for 4th place finish (9 from United, 5 from Spurs and 4 from Everton), and we might get very close to Chelsea, who have to play against City at the Etihad on Monday.
As for our tactics, as good as we were against Everton I don't think we should go with the same approach again. The derby was exactly that, a derby, where tactics are not as important as motivation and the will to win. We were extra motivated and made every touch of those 40% possession count. I'm not talking just about Gerrard, I'm talking about the entire team. I honestly doubt that we'll see similar performance again and knowing that WBA have a tough midfield themselves with players such as Mulumbu and Yacob I think that we should play it safe and play Allen in that midfield of ours. This is what I'd go for:
Mignolet
Kelly Skrtel Toure Flanagan
Gerrard
Hendo Allen
Sturridge Suarez Coutinho
