Born in
Bamberg, Koch arrived in the
Bundesliga at already 26, with
1. FC Kaiserslautern, after having played amateur football, and quickly became an undisputed starter. In
1997–98, he played in 31 matches as the club won the national league straight out of the
second division. In 2003, after 187 matches with 17 goals in the first division, Koch moved to
SV Eintracht Trier 05, closing out his career three years later. Immediately after, he took up coaching, replacing Werner Kartz at the helm of lower-level team SV Dörbach. ==Honours==
