Athletic Bilbao striker Fernando Llorente admits tonight's game with Espanyol is the biggest of the season.
Athletic make the trip to the Cornella-El Prat stadium lying six points clear of eighth-placed Espanyol and with just four rounds left after the match, the Basque side could all but make their position in the top seven impregnable with a win.
Llorente said: "It's the most important game of the season for what it could mean.
"If we win, we will be in Europe. Espanyol are the team who are just outside the European places, and the following week they have to go to the Nou Camp to play Barca, who are playing for the league."
