Borussia Dortmund manager Jurgen Klopp, a reported target for Chelsea, wants to provide new Bayern Munich boss Pep Guardiola with the same level of competition as Jose Mourinho did with Real Madrid.
Guardiola will become the Bayern Munich coach in the summer after the retirement of Jupp Heynckes having decided to enter back into the game having taken a year out after leaving Barcelona.
The 41-year-old Catalan had numerous heated battles with Mourinho's Real Madrid during his time with Barcelona, and Klopp is now determined to take the place of the former Chelsea manager.
Klopp, who is reported to be among the targets of Chelsea owner Roman Abramovich, is determined to stay with Borussia Dortmund and provide Guardiola with the type of challenge he faced in El Clasico.
"I want to become Guardiola's new Mourinho. We want to be an unpleasant opponent for Bayern in the next few years," Klopp told Sport Bild.
"If Pep Guardiola doesn't like me during the game or because of the result, that's not a problem.
"I do not believe that Pep has bad feelings toward his rivals, though. I think that I will get along very well with Pep. I have a good relationship with Mourinho as well."
Guardiola, meanwhile, is likely to be an interested spectator on Wednesday as Mourinho and his Real Madrid side take on Barcelona, now managed by Tito Vilanova, in the semi-final of the Copa del Rey.
Barcelona are holders of the trophy, having beaten Athletic Bilbao in the final last season - Guardiola's final game as the club's manager.
