Defending champions Barcelona face a tricky trip to Anoeta to take on Real Sociedad on Saturday in La Liga.
Imanol Alguacil's side have enjoyed a strong start to the 2019-29 season and are in fourth place in the Spanish top flight, just seven points off the top of the table.
Barcelona have struggled on their travels against Sociedad in La Liga and have won only two of their last nine visits. They may also have one eye on Wednesday's Clasico against Real Madrid.
