Career
Mainly a right back who could also appear as a midfielder, he possessed a thunderous right-foot shot, often scoring from free kicks, and played most of his career for Borussia Mönchengladbach. Deemed surplus to requirements after having appeared in only nine games for the 1990 champions, Kastenmaier joined Borussia Mönchengladbach, scoring nine goals in two separate seasons, while also helping the club to the 1995 German Cup. He retired in 1998 after two injury-ravaged seasons, subsequently beginning his managerial career, starting with Borussia"s amateurs.
