Borussia Dortmund could be boosted by the return of attacking midfielder Shinji Kagawa.
The Japan international missed the German Bundeliga leaders' last outing against Hertha Berlin because of injury but could be back for Sunday's home clash with Hannover 96.
Dortmund captain Sebastian Kehl says the inclusion of Kagawa, who has scored four goals in his last four outings in the absence of Mario Gotze, will be vital for the reigning champions.
"It is looking good for Shinji and I hope he can be with us on Sunday," Kehl told reporters. "Our medical team is doing fantastic work."
