Real Zaragoza are facing relegation from La Liga should they lose to Athletic Bilbao on Sunday afternoon.
If Zaragoza go down, it would be the third time in 10 years that Los Maños have been relegated from Spain's top tier.
Manolo Jiménez's side's 1-0 defeat to Mallorca last week has left them six points behind Villarreal in the table and with just four matches remaining and an awful goal difference, the odds are stacked against survival.
Bilbao meanwhile, are still in contention for a top-four finish and Champions League football, and the club is on a high following their qualification for the Europa League final this week.
A late strike from Fernando Llorente for Athletic saw them overcome the challenge of Sporting Lisbon 4-3 on aggregate, to set up an all-Spanish Europa League final with Atletico Madrid.
And now the Basque club are within touching distance of their first continental trophy, they'll be determined to keep their Champions League hopes alive with victory today.
Bilbao trail fourth placed Levante by four points, but have a game in hand and should consign Zaragoza to the drop this afternoon.
