Thimm played professional basketball for the
West German Basketball Bundesliga teams
SSV Hagen,
TuS Bayer 04 Leverkusen and the
Spanish ACB team
Real Madrid. In 1972 Thimm became the first German basketball player to ever play professional basketball for an international team. Even though Thimm constantly was among
Real Madrid’s top performers, he never consistently made it into the starting lineup. Besides winning two Spanish Championships and two Spanish Cups, Thimm has won five German Championships and five German Cups and remains one of the most successful German basketball players in history. ==West German national team==
