I think we have a big enough squad to focus on both but injuries to key players is beginning to take it's toll on the our form. We're usually very strong vs teams outside the top 4 though and we have a good run of winnable games coming up. That Arsenal game in May is looming large though (you lot are playing United on the same day so it could be a do or die doomsday for us all).
Just checking the remaining schedule, Arsenal is our only remaining top 4 clash while Arsenal, City and United all have to face each other once each, which could work in our favour :)
