Sep.9 (GMM) After a disappointing season so far alongside the impressive Nico Rosberg, Austrian veteran Wurz is yet to have his Williams deal renewed.

Sir Frank Williams admitted here at Monza that he is yet to decide who Rosberg's teammate will be next year.

Prodrive was touted as one possible alternative for Wurz, as the 33-year-old retains close links with boss David Richards from his days as a Benetton racer.

But Wurz is quoted as saying by sportnet.at: "(Richards) needs someone who can bring money. And I do not bring any money."

He even criticised those small formula one outfits that try to bolster their annual budgets with the bulging wallets of pay-drivers.

"As soon as teams begin to get drivers based on their sponsorship value, they never get away from the rear of the field," said Wurz.
