Taking into account Barcelona’s game against Young Boys in the Champions League midweek, Flick might opt to give rest to some of the regular starters. Therefore, it is possible for the Catalans to lineup in any viable combination against Osasuna.
What is certain is Barca’s list of long term injuries who are in no way capable of playing this fixture. This list comprises of Marc Andre Ter Stegen, Ronald Araujo, Andreas Christensen, Dani Olmo, Frenkie De Jong, Gavi, and Fermin Lopez.
Defense
Inaki Pena is set to feature in the Barca goal due to the lack of availability of any other alternatives. Hector Fort could potentially feature in place of Kounde at right back, who is long overdue to get rested for a fixture. The center back pairing could potentially comprise of Pau Cubarsi and Eric Garcia, which would allow Inigo to get some rest. Alejandro Balde is most probable to start at left back, but Flick could look to start Gerard Martin against Osasuna if he would prefer Balde to be rested.
Midfield
Most of Barcelona’s midfield options are out due to injury, hence there is not much room to rest the players. Pedri is certain to start as he got his fair share of rest against Getafe. Additionally, Marc Casado and Pablo Torre are expected to start alongside him to form a trident of young Spanish midfielders against Osasuna.
Attack
Contrary to what Flick said recently, Lamine Yamal is due to be rested as he has started every game of the season thus far. This would mean that Ferran Torres would get the nod in the starting 11 against Osasuna. Additionally, the pairing of Raphinha and Robert Lewandowski are also set to play this fixture out.
