BERLIN (AFP) - Borussia Dortmund aim to ruin Bayern Munich's plans to say goodbye to Pep Guardiola with a seventh title in three years when Germany's top teams meet in Saturday's crunch German Cup final.
Victory over their main rivals at Berlin's Olympic Stadium would give Bayern the league and Cup double before Guardiola leaves for Manchester City next season.
After Bayern lifted the Bundesliga title last weekend, for a record fourth season in succession, Dortmund now want the Cup to compensate.
"We will do everything to win," promised Guardiola, who admits it will be tough against "the best Borussia (team) in history".
Borussia finished 10 points behind Bayern in the league and want to avoid losing their third straight German Cup final.
Dortmund controversially lost the 2014 final 2-0 to Bayern, after extra time, and were beaten 3-1 by Wolfsburg in last year's final.
As midfielder Sven Bender put it, Dortmund has "no desire to lose for a third time in succession in Berlin".
There is plenty of spice in the Olympic Stadium showdown with a sell-out crowd of 74,322 expected.
"This is actually the best final that one can imagine in Germany," enthused World Cup-winning coach Joachim Loew.
Mats Hummels will be playing his final game before becoming the third Borussia Dortmund star to join Bayern in the last three years, after Mario Goetze and Robert Lewandowski.
The Dortmund captain expects a difficult afternoon: "It's a strange feeling. Every mistake I make will be endlessly dissected."
The German league's top three strikers will be also be shooting it out.
Top-scorer Lewandowski, the first foreigner to score 30 Bundesliga goals in a single season, will partner Bayern's Thomas Mueller, who netted 20 league goals. But Dortmund striker Pierre-Emerick Aubameyang, who hit the net 25 times in the Bundesliga, has predicted he will score twice in the final.
