Bayer Leverkusen manager Sami Hyypia expects a physical challenge from Kaiserslautern when the two sides meet in the quarter-finals of the DFB Pokal at the BayArena on Wednesday night.
Leverkusen, who are 13 points adrift of Bundesliga leaders Bayern Munich and second in the top-flight standings, will take on their second-division opponents as they bid to win the tournament 11 years after their only victory.
Hyypia refuses to take Kaiserslautern lightly and has warned of a bruising encounter.
"A cup match is always something special," Hyppia told the club's official website.
"Especially in front of their fans.
"FCK have a very robust team that is very strong physically. You always go right into the duels and have to have the players for it.
"If our quality comes through, we can win the game.
"It's the quarter-finals and we will only talk about the quarter-finals."
Eintracht Frankfurt will host Borussia Dortmund on Tuesday fresh from their 3-0 league win over Eintracht Braunschweig which lifted them away from the bottom three.
Dortmund, meanwhile, kept up their pursuit of second-placed Leverkusen with an emphatic 5-1 win over Werder Bremen, but the victory came at something of a cost for manager Jurgen Klopp.
Dortmund will be without midfielders Sven Bender and Marco Reus for the game after they both suffered thigh injuries in the match against Bremen on Saturday.
Bender was diagnosed with a strained right thigh muscle, ruling him out for up to one week, while Reus looks set to be out for two weeks after tearing a muscle, according to team doctor Markus Braun.
They will join defender Mats Hummels and midfielder Ilkay Gundogan on the sidelines, while Jakub Blaszczykowski and Neven Subotic have both already been ruled out for the season.
Hamburg face Bayern Munich on Wednesday, with coach Bert van Marwijk receiving backing from the club's board following the latest home defeat to Hertha Berlin.
That sixth straight loss has left the northern club in serious relegation danger and led to hundreds of fans protesting outside the ground, blocking the players' exit from the HSV Arena and pelting them with missiles when they tried to leave.
Chief executive Carl Jarchow said: "The board came together after the game (on Saturday) and analysed the current situation.
"We have agreed with the board's decision to continue with Bert van Marwijk.
"Here are the three major issues that were at the centre: has the coach achieved with the team yet? Is he determined enough? Does he have a plan?
"We have answered all three questions with a resounding yes."
The other quarter-final sees Hoffenheim face Wolfsburg.
