Bayer Leverkusen come into this one with four points from their opening three Bundesliga games, sitting tenth in the table, and that recent 2-2 draw at Augsburg tells you plenty about the mood around the BayArena right now. Patrik Schick popped up with a late equaliser to rescue a point, and while Carles Martínez will be pleased with the character, he will know his side cannot keep relying on late heroics. The positive is that Leverkusen are creating chances and scoring goals, even if the defensive solidity that once defined this club has been a little patchy. At home, though, they remain a different animal, and the BayArena has historically been a fortress where visiting sides struggle to dictate terms.

RB Leipzig arrive with their own questions to answer. Martin Demichelis has had to juggle a squad missing key men, with Christoph Baumgartner and Rocco Reitz both sidelined through hamstring and thigh injuries respectively, and that strips the visitors of creativity and legs in the middle of the park. Leipzig's recent form has been mixed, and their away performances in the early part of this campaign have not convinced anyone that they can go to a place like Leverkusen and dominate. The momentum, marginally, sits with the hosts, who have shown they can dig out results even when not at their best.
