I disagree. We should beat Arsenal yes, But Beating United at Old Trafford is not a must. I'd take a draw right now tbh, United are a good side as there showing this season. If Nani put in a performance like he did today we'll see how good our defence is. United won the league last season by Drawing and Losing to Arsenal, Beating and Drawing to us, And Losing twice to Liverpool. We have already have achieved nearly double that. People say Arsenal will sink, No way will that happen. Vermalaen has been sensational for them this season. Fabregas is the form player in the league atm, and there scoring for fun without Van Persie. Its time to stop thinking that this league will be a breeze. This could be the closest league for a long time. Its a 3 horse race, All teams look evenly matched, All have one Talisman. Personally, I think our strength in depth will get us over the finishing line, But anything can happen. Open your eyes people.
