Apart from the 4 tough away games at Utd, Arsenal, Liverpool and Everton we have at least 1 difficult home game v Southampton. Of these I think the key game if we are to win the title, is Liverpool away, especially if Chelsea beat Arsenal next weekend, and then as I believe they will, Liverpool beat Chelsea at Anfield a few weeks later.
I think Liverpool are possibly the main opponents for the Title, as Arsenal are a little bit more vulnerable with Walcott, Ramsay and Ozil currently injured (Hopefully still unavailable when we go to the Emirates in a couple of weeks)
We should (unless the team doses off like it did against Wigan) be able to beat Palace away and Fulham, WBA, Sunderland, West Ham and Villa at home. We cannot afford to drop a single point from any of our home games.
Thought - if Utd finish outside of the top 6 they will not play in Europe at all next season, hope that does not have the same effect on them next season as it has with Liverpool this season !
