Bayern Munich coach Pep Guardiola is not taking high-flying Bayer Leverkusen lightly ahead of the much-anticipated match on Saturday.
Guardiola's men will travel to the BayArena on the back of a terrific 3-1 UEFA Champions League win at Manchester City on Wednesday.
The European champions sit second in the Bundesliga but are just one point ahead of the in-form Leverkusen.
Sami Hyypia's men recorded a superb Champions League win of their own on Wednesday, as Jens Hegeler's stunning stoppage-time free-kick saw them beat Real Sociedad 2-1.
Leverkusen have won six of their seven league matches this season and Guardiola paid his respects to them, and Hyypia, ahead of Saturday's difficult road trip.
"They are just one point behind us, but they have played very well until now," Guardiola said.
"In the Champions League they secured an important win against (Real) Sociedad. They are well organised in defence and dangerous on set pieces, so are a very dangerous team.
"They have a young manager with Sami Hyypia. He was great when he was playing, a strong defender with Liverpool. He played well with Rafa Benitez.
"It's going to be a huge challenge for us, after the match on Wednesday (the 3-1 win at Manchester City)."
Bayern will be hoping to maintain their unbeaten Bundesliga run, which stands at 32 matches, in the fixture.
They last lost a league game in October last year, when Stefan Kiessling and Sidney Sam scored as Leverkusen won 2-1 in Munich.
