Marco Reus, Nuri Sahin and Jonas Hofmann are all expected to play some part in Saturday's encounter at home to Hannover 96 after injury, while left back Erik Durm should also be available following a cold.
Ifs and buts
Whether or not Sven Bender and Marcel Schmelzer will be in a position to join their fit-again colleagues remains to be seen. "I'll know for certain who and who isn't available [after training on Friday]," explained Klopp.
Lukasz Piszczek (hip), Sebastian Kehl (ankle), Ilkay Gündogan (back) and Mats Hummels (suspended) will definitely miss out, but Klopp is nevertheless in no doubt he will be able "to put together a good team" as BVB look to bounce back from their first league defeat of the campaign against Borussia Mönchengladbach on Matchday 8.
