Heidenheim, which upset Bayer Leverkusen in the third round on Tuesday, faces a daunting task in Munich as Bayern continues to chase a record-extending 19th German Cup title. "(We) will give everything so that we don't give ourselves away cheaply in this David vs. Goliath duel," Heidenheim chairman Holger Sanwald said.
The games will be played on April 2 and 3.
