Borussia Dortmund will be without right-back Lukasz Piszczek for the Bundesliga match against Stuttgart on Saturday.
• Buczko: Dortmund can't afford half effort
Goalkeeper Roman Weidenfeller and winger Pierre-Emerick Aubameyang are also doubts for Juergen Klopp’s injury-hit side with colds, but should be fit.
Sven Bender, Ilkay Gundogan, Marcel Schmelzer, Neven Subotic and Jakub Blaszczykowski are already ruled out as Dortmund prepare for seven matches in 21 days which will decide their fate in the Bundesliga, Champions League and DFB Pokal.
At his prematch news conference on Thursday, Klopp explained that Piszczek had trained individually due to muscular issues, saying: “His problem is more than just a niggle.”
Dortmund, who face Real Madrid in the Champions League quarterfinals next Wednesday, have only won four of their eight matches ahead of European nights this season, leading some in the German media to question whether instead of going full-throttle ahead of the European games they put the handbrake on.
But Klopp has disputed that notion and insisted they are fully focused on the task in hand against Stuttgart this weekend.
“We might have lost one or two games too many, but there have been reasons for it and they have nothing to do with Champions League,” he said.
“We don’t think about getting Champions League out of our heads, because, right now, Real is still far away.
“We are only focused on our next task. You can put a lot of things on us, but not that we were not willing to give it our all in one or two games.”
