After claiming impressive wins over Real Madrid and Bayern Munich, Borussia Dortmund are eyeing a German Cup final berth in Berlin when they host VfL Wolfsburg in Tuesday's semi-final.
Dortmund bowed out of the Champions League last Tuesday despite a stunning 2-0 win at home to Real Madrid, losing the quarter-final 3-2 on aggregate, then they shocked Bundesliga champions Bayern 3-0 in Munich on Saturday.
It was Bayern's heaviest home league defeat since 2008 and the two Bundesliga giants could meet in this year's final at Berlin's Olympic Stadium on May 17 as Pep Guardiola's Munich host second-division Kaiserslautern in Wednesday's other semi-final.
"We're not thinking about that yet, we have to beat Wolfsburg on Tuesday and we have already seen how strong they are," said Dortmund's Germany winger Kevin Grosskreutz.
Borussia had to come from a goal down to beat Wolves 2-1 in the league at Dortmund's Westfalenstadion ten days ago in the semi-final dress rehearsal.
Klopp's side have a quick turn-around before hosting Wolves, who romped to a 4-1 win at home to Nuremberg on Saturday and are just outside the top four in the league.
"But we'll be putting in another passionate performance like we did against Real and Bayern," promised Grosskreutz.
Meanwhile Bayern boss Guardiola has demanded an immediate reaction in Wednesday's other semi-final with the Bavarian giants reeling from consecutive league defeats.
Bayern face Real Madrid in the Champions League's semi-finals later this month and are bidding to repeat last year's treble of European, league and cup titles.
But their shock defeat at home to Dortmund, with a full-strength side, did little to boost confidence.
The Bavarian giants are winless in their last three league games since wrapping up the Bundesliga title with a record seven games to spare.
"We want to see the real Bayern Munich again. We need much better performances than against Dortmund," said director of sport Matthias Sammer.
Giant-killers Kaiserslautern knocked Champions League side Bayer Leverkusen out of the cup in the quarter-finals and Bayern need to be on their guard against the 'Red Devils' who are pushing for promotion to Germany's top flight.
Bayern's Germany goalkeeper Manuel Neuer missed the second-half of the Dortmund defeat with a minor calf problem, but expects to play on Wednesday.
"We simply had a bad day at the office, but I'll be fine for Wednesday. It was just a precaution," said Neuer.
Should Bayern and Dortmund book their Berlin places, the Bavarian giants will be seeking revenge for their 5-2 defeat in the 2012 cup final when Borussia's Robert Lewandowski, who will join Munich at the end of the season, scored a hat-trick.
