After seven years, two German league titles and a 2013 Champions League final appearance, the 47-year-old will leave Borussia at the end of the season and will be replaced by ex-Mainz coach Thomas Tuchel.
Klopp is targeting a place in the final on May 30 and will be presented with a floral bouquet in Munich.
But he says he is more interested in his team giving Pep Guardiola’s side a proverbial black eye by ending the Bavarians’ dreams of repeating their 2013 treble of European, league and cup titles.
“(The bouquet) is a very nice touch, but we’ll be spoiling for a fight on Tuesday and we don’t want to be softened up by flowers,” Klopp said after Saturday’s 2-0 win over Eintracht Frankfurt.
Pierre-Emerick Aubameyang converted a penalty and set up Shinji Kagawa as Borussia beat Eintracht to go within three points of a Europa League place.
Klopp is targeting a top-six finish having started February bottom of the table after a dire run of results in the first half of the season.
“Today was a step in the right direction. Now we have to attack and say to hell with it,” Klopp added.
“I don’t know if we can still slide in up there, but it’s our turn to take three points.
“Now there is everything to play for and I hope we can sneak in there somehow.”
Aubameyang claimed his 20th goal of the season against Frankfurt when he converted an early penalty, then provided Kagawa with the final pass to score Dortmund’s 34th-minute second.
The Gabon winger has filled Robert Lewandowski’s boots as Dortmund’s top scorer since the Poland striker joined Bayern at the end of last season.
Dortmund have a tough league run-in as they face Hoffenheim, who are also chasing a European spot, Hertha Berlin, Wolfsburg and Werder Bremen.
