Last season was memorable for Dortmund fans, but for all the wrong reasons. An ignominious 2-0 defeat to Bayer 04 Leverkusen at home on Matchday 1 set the tone for a wretched Hinrunde: only four wins in 17 games left die Schwarz-Gelben a place from bottom over the winter break. The unthinkable did happen when BVB slipped to 18th in February, although coach Jürgen Klopp masterminded a revival-of-sorts, inspiring his troops to a seventh-place finish and UEFA Europa League qualification. The legendary tactician called time on his era at the Signal Iduna Park at the end of the campaign, his final game a 3-1 defeat to VfL Wolfsburg in the DFB Cup final.
