Having rested several key plays for Saturday's defeat to Barcelona, Marcelo Bielsa should reincorporate the likes of Ander Herrera, Iker Muniain and Fernando Llorente. Ibai Gomez and Gaizka Toquero are likely to settle for a place on the bench, while Ander Iturraspe and Fernando Amorebieta are suspended for this game.
For Schalke, Lars Unnerstall should make his European comeback, having surprisingly started against Hoffenheim on Sunday. However, fellow goalkeepers Ralf Fahrmann and Timo Hildebrand remain sidelined.
Benedikt Howedes and Christoph Metzelder are still injured and Huub Stevens will be without left-back Christian Fuchs, who is ill. In midfield Lewis Holtby is in with a chance to replace Marco Hoger, who disappointed in the 2-4 loss to Athletic Bilbao. As well, Stevens has decided to give left-winger Julian Draxler a rest during Thursday's match.
