In 2000 it was agreed that Christoph Daum, coach of Bayer Leverkusen, would become national coach in the summer of 2001. On 1 October 2000, the Bayern manager Uli Hoeneß hinted in a newspaper that Daum used drugs. On 9 October Daum gave a hair sample of his own accord. Ich tue das, weil ich ein absolut reines Gewissen habe. I am doing this because I have an absolutely clear conscience. On 20 October he was told the result from the Institute of Forensic Medicine of the University of Cologne. It showed cocaine. Leverkusen dismissed him without notice, and Gerhard Mayer-Vorfelder, then acting head of the DFB, declared: Der Handschlag-Vertrag mit Daum ist gegenstandslos. The handshake contract with Daum is void.
