Pierre-Emerick Aubameyang's late winner against Eintracht Frankfurt secured Borussia Dortmund a berth in the DFB Cup semi-finals.
In an intense match Tuesday, resilient Frankfurt made Dortmund's life difficult as Juergen Klopp's men needed 83 minutes to break the deadlock and edge their opponents 1-0, reports Xinhua.
Dortmund took the wind out of Frankfurt's sails when Aubameyang headed home a corner at the back post with seven minutes remaining.
"In both halves we had a better start. Nonetheless, you have to take advantage of your opportunities," Frankfurt coach Armin Veh said.
