Review and events
In the 2011–12 season, Bayer Leverkusen finished fifth in the 2011–12 Bundesliga. Therefore the club qualified for the 2012–13 Bundesliga, 2012–13 DFB-Pokal and 2012–13 Europa League.

Bayer Leverkusen rejected a bid for André Schürrle worth €25 million from Chelsea. Bayer Leverkusen has decided not to sell Schürrle because they were "unable to sign a replacement" because suitable replacements are "too expensive" and would be forced to sign "a weaker player" who is "overpriced". Leverkusen CEO Wolfgang Holzhäuser accused Bayern Munich coach of Jupp Heynckes "tapping up" Lars Bender. The club had rejected an "official" offer from Bayern Munich the previous week.
