Borussia Moenchengladbach battled past VfL Wolfsburg 1-0 with a goal in the last minute of extra time through Manu Kone on Tuesday to move into the German Cup last eight.
The Foals struck on the break with Kone nodding in at the far post after a quick move at the end of a game that had few highlights over 90 minutes.
Wolfsburg had missed two golden chances in second half stoppage time through Jonas Wind to snatch a late winner.
Bundesliga leaders Bayer Leverkusen take on Paderborn on Wednesday while Borussia Dortmund travel to in-form VfB Stuttgart for a place in the last eight.
