Pep Guardiola believes Bayern Munich are in for a tough test against Bayer Leverkusen on Saturday.
German champions Bayern return to action for the first time since it was announced that coach Guardiola will join Manchester City at the end of the season when they visit the BayArena on Saturday.
Guardiola made it clear on Friday that Bayern's fight for honours on three fronts would retain his focus until he leaves for Manchester, and warned his players to be on their guard against Roger Schmidt's side.
In-form strike duo Stefan Kiessling and Javier Hernandez have helped Leverkusen up to fourth in the Bundesliga standings but Guardiola believes they carry threats all over the field.
"Leverkusen are more than just Chicharito [Hernandez] and Kiessling. We are definitely facing one of the best teams in Germany," he said.
"They play very intense, that is good for us. It will be difficult.
"If Leverkusen play high balls in to the box we'll have problems, but then everyone struggles against Kiessling."
Guardiola's defence will be without the injured Jerome Boateng (groin) and Javi Martinez (knee), while midfielder Joshua Kimmich was deployed at centre-back during last weekend's 2-0 win over Hoffenheim.
"He'll train in two to three days," Guardiola said of Tasci. "He'll help us. He has experience, is fast and good on the ball."
Nevertheless, Guardiola is keen to proceed cautiously with the Germany international.
"I missed Holger for a long, long time," he added. "He has a big heart and is a top, top player."
"But someone like Holger needs a break sometimes and it is right therefore that the club brought in Tasci."
