Mats Hummels has admitted the boys at Dortmund are desperate to beat their former manager, Jurgen Klopp when he comes to Signal Iduna Park.
Klopp managed BVB between 2008 and 2015, winning two league titles and taking them to the UCL final in 2013.
The German manager who is now in charge at Liverpool, will face his old club in the Europa league.
And Hummels, who admits the return will be emotional, wants a win against his former manager.
“The tie with Liverpool is one where we are simply desperate to beat Klopp. We have to beat him,” Hummels told ZDF.
“Of course, he will get a warm welcome and a warm farewell. But I hope to drive him mad in between.
“There will be a lot of media attention. And it will be something special for the players to meet Klopp again. It will be very interesting, also on an emotional level.
“But I try not to think about it too much yet. I already said after we were paired with Liverpool that we will start thinking about it when the game is actually around the corner.”
The first leg at the Signal Iduna Park takes place on April 7, with the return at Anfield scheduled for April 14.
