Rot-Wiss Essen from the German fourth division came back in extra-time to beat Bayer Leverkusen 2-1 to qualify for the German Cup quarter-finals.

Simon Engelmann snatched an unlikely winner in the 117th minute for Essen, who knocked out second division Fortuna Dusseldorf in the last round and last lifted the Cup back in 1953.
