Adrie Koster

He played for Roda JC (1977–79) and PSV Eindhoven (1979–83). He played his last match in the Eredivisie on 2 October 1982, replacing Jurrie Koolhof. In the following season 1983/1984 he retired from professional football as a player.

Two years later, Huub Stevens took over as head coach and Koster returned to the Eerste Divisie to coach first Helmond Sport and since TOP Oss, before moving to Excelsior in 1997.

His next coaching job was RKC Waalwijk, where Koster was dismissed after a year due to poor results in 2006.
