Since taking over for the second time, Schalke have seen much success, including a 1997 UEFA Cup win, and victory in the DFB-Pokal finals of 2001 and 2002. Schalke narrowly lost the Bundesliga title race in 2001 in the very last minute to Bayern Munich, which was described as the most bitter moment in his career. Assauer also oversaw the development of a brand new stadium for the club. In May 2006, Assauer was suspected of giving away secret information concerning the financial problems of Schalke, so the club and Assauer parted company.
