Young forward Ansu Fati is having a hard time finding playing time in the past few games. Against Napoli, Real Madrid, and Real Sociedad, Fati only got 17 minutes. This even though Luis Suárez and Ousmane Dembélé are injured, and Martin Braithwaite is ineligible for UEFA Champions League games.
The youngster could still be in line to start against Real Sociedad with Arturo Vidal and Sergio Busquets suspended, and Arthur struggling for fitness. Quique Setién had opted for using four midfielders in his starting XI but that seems less plausible now.
