The first fixture of LaLiga Santander in 2021/22 and the first match of life after Lionel Messi will pit Barcelona up against Real Sociedad.
The champions of the 2020 Copa del Rey will provide a tough test at Camp Nou with a talented young squad.
Barcelona preview and expected line-ups
On Saturday, Barcelona confirmed the registration of Memphis Depay, Eric Garcia and Rey Manaj, meaning that the former is likely to come into contention to start for Ronald Koeman's side.
The Dutch coach faces a decision in attack, with Yusuf Demir likely to start after impressing in pre-season, opting to leave Martin Braithwaite on the bench.
Another option for Koeman to choose between is in midfield, where Pedri may be rested depending upon if Frenkie de Jong recovers from a knock.
With no Marc-Andre Ter Stegen as he recovers from surgery, Neto will start in goal for the Catalan side.
Expected line-up: Neto; Sergino Dest, Gerard Pique, Ronald Araujo, Jordi Alba; Sergi Roberto, Sergio Busquets, Frenkie de Jong; Antoine Griezmann, Memphis Depay, Yusuf Demir.
Real Sociedad preview and expected lineups
Unlike Barcelona, who have Pedri back in the squad after the Olympics, Imanol Alguacil may not be able to count on Martin Zubimendi, Mikel Merino and Mikel Oyarzabal.
Summer signing Mat Ryan also underwent surgery and will miss out, meaning Alex Remiro will start in goal.
Also out injured is Alexander Isak, while his backup Carlos Fernandez is out too. That leaves a void up front.
Expected line-up: Alex Remiro; Andoni Gorosabel, Aritz Elustondo, Ruben Le Normand, Aihen Munoz; Ander Guevara, Asier Illarramendi, David Silva; Portu, Adnan Januzaj, Ander Barrenetxea.
