Dortmund must always play with a knife between their teeth - Aubameyang

The versatile attacker calles on his BVB team-mates to play with drive and determination until the end of the season after confirming their progress to the DFB-Pokal semi-finals
Pierre-Emerick Aubameyang believes that anything is possible for Borussia Dortmund if they continue to play with the same passion that they displayed in Tuesday's DFB-Pokal quarter-final win over Eintracht Frankfurt.

A single Aubameyang strike saw Jurgen Klopp's men progress to the final four and the attacker has urged his team-mates to show more of the same kind of drive and determination in the weeks to come.

"If we - like against Frankfurt - play with a knife between our teeth and fight until we drop, we can go far in every competition," the former Saint-Etienne star told the club's official website.

"There's a lot of quality in the squad. We can achieve much more if we stick together."

The 24-year-old then went on to voice his delight with his decisive strike in a hard-fought game against Frankfurt.

"I'm very happy about my goal as we had to work very hard for it," Aubameyang enthused. "It was a difficult game so we can be very happy about this win."

Dortmund were eliminated in the quarter-finals of the competition last season by eventual winners Bayern Munich. They last won the DFB Pokal in 2011-12.
