will continue his push towards formula one with different management. Amid Sauber
's financial struggle this season, the Swiss team's Dutch reserve driver - rated highly in the paddock but not heavily sponsored - lost his job.
So 22-year-old Frijns, also in and out of GP2 seats this year, revealed recently he has teamed up with Just Sports Marketing in a bid to secure backing. But Werner Heinz, who is Nico Hulkenberg
's manager and earlier worked with Nick Heidfeld
, remained Frijns' manager.
However, Frijns has now announced that he has split with Heinz "with immediate effect". "Unfortunately, my career is somehow stuck now," he explained, "and I hope that these changes will help me to do some important steps forward."
Frijns said he will appoint a new manager "very soon". (GMM)
