Jan.11 (GMM) Nick Heidfeld will have a new personal manager for his formula one career.

The existing contract between the BMW-Sauber racer and his current manager, Werner Heinz, runs out after Christmas this year.

Andre Theuerzeit, managing director of the sports communication agency b.a.n.g., will take over after that, following a transitional period where both men will share the duties in 2008.

Dr Stefan Seitz, meanwhile, has become Heidfeld's legal advisor, a statement added.

"After a long and successful cooperation with Werner Heinz, who has been my Manager so far, I decided at the end of the contract period to choose a new management path," Heidfeld told the motor sports magazine adrivo.com.
