Real Sociedad have only won three times at at the Nou Camp in their last 70 visits, last winning in 1991, and have lost 60 times in Catalonia.
Sociedad coach Imanol Alguacil has shuffled his deck significantly with six changes overall, bringing in Moya, Elustondo, Llorente, de la Bella, Zurutuza and Januzaj. Odriozola, Rulli and Canales drop to the bench, with Hector Moreno injured. 34-year-old Prieto, who's spent his entire career with the Basque side, is retiring after the game.
Ernesto Valverde makes just one change to the side beaten by Levante last week, replacing Thomas Vermaelen with Gerard Pique.
