La Blaugrana are yet to lose an exhibition contest this summer and edged out El Clasico rivals Real Madrid 2-1 at the weekend, where young attacker Pau Victor was on target twice.
The 22-year-old will no doubt continue in a Barca side without Olympic participants Eric Garcia, Pau Cubarsi and Fermin Lopez, as well as Euro 2024 winners Lamine Yamal and Ferran Torres.
Vitor Roque, Frenkie de Jong, Pedri, Gavi, Ansu Fati and Ronald Araujo are also nursing injuries and will play no part in the contest, nor will Oriol Romeu, who is on the verge of a return to Girona.
There is scope for head coach Flick to make a central change, though, as Ilkay Gundogan was only a late substitute in El Clasico but could now return to partner Marc Casado in the middle.
The pair may operate just behind Pablo Torre in the number 10 role, while the in-form Victor, Raphinha and Robert Lewandowski are poised to complete the attacking quartet.
Further back, Marc-Andre ter Stegen, Inigo Martinez, Andreas Christensen and Alejandro Balde are expected to reprise their roles, but Hector Fort might demote Alex Valle to the bench.
Barcelona possible starting lineup:
Ter Stegen; Fort, Christensen, Martinez, Balde; Casado, Gundogan; Victor, Torre, Raphinha; Lewandowski
