However, if Fritz does play on Wednesday (kick-off: 20:00 CET) in Leverkusen, he has to remember that he is one yellow card away from a suspension, with the combative leader already on nine bookings for the season. Zlatko Junuzovic and Felix Wiedwald are also one away from a suspension.
Claudio Pizarro, Santiago García and Theodor Gebre Selassie are all fit for yet another meeting with Bayer. The trio have been working individually in the weights room since the start of the week. However, this game has come too soon for Janek Starnberg, who only returned to full training with the team on Monday.
These are the 18 players included in the squad to face Leverkusen:
Wiedwald, Tremmel – Santiago García, Djilobodji, Gálvez, Yatabaré, Kleinheisler, Vestergaard, Fritz, Öztunali, Veljkovic, Pizarro, Junuzovic, Ulisses García, Ujah, Bartels, Gebre Selassie and Grillitsch.
