Lionel Messi will miss a third consecutive FC Barcelona game due to injury.
The club captain was ruled out of the opening day defeat at Athletic Bilbao and last weekend's 5-2 home win against Real Betis - and the club have confirmed that a calf problem will keep him out of the trip to the El Sadar Stadium.
Manager Ernesto Valverde will also be without fellow forwards Luis Suarez and Ousmane Dembele through injury, with Junior Firpo and Carles ALena also ruled out.
