Barcelona have one immediate objective, one moral victory in mind, and one medium-term big goal as they take on Espanyol.
First of all, Barça have to win to keep their relatively slim title hopes alive. Not winning would spell certain doom for their La Liga campaign. The next mission is to boost morale, by continuing the good feelings from their 4-1 win over Villarreal. That a win would also send bitter rivals Espanyol down to the Segunda is just a cherry on top for the good mood the team would be in.
