The Bayern Munich sporting director has called for an improved performance from the side as they look to avoid an upset against the minnows
The Bavarians entertain the 2. Bundesliga outfit as they look to retain the competition they won last year and set up a final date with either Borussia Dortmund or Wolfsburg.
The Fritz Walter Stadion side eliminated Bayer Leverkusen in the quarter-finals and Sammer says they must be careful to avoid another upset.
"It's a final for us," he told reporters.
"The lads know exactly not to follow Leverkusen's example. We need to produce a better performance than we did against Dortmund."
Bayern chairman Karl-Heinz Rummenigge echoed Sammer's thoughts: "It will be important for us not to underestimate the opposition.
"They showed what damage they can do against a Bundesliga team at Leverkusen.".
