Vitaly Petrov's manager has admitted that he will be without a drive in 2013 if he fails to come up with the right sponsorship.
The Russian was initially left without a drive for this season after Lotus dumped him, but he managed to secure a seat at Caterham after he came up with the right financial support.
However, he only signed a one-year deal with Caterham and he will once again need to come up with the right money to secure another contract.
His manager Oksana Kosachenko says they have halted talks about Petrov's future for the time being, but confirmed he will be without a seat if he doesn't find sponsors.
"We've taken a timeout now," she told RIA Novosti. "I need time to consolidate all our financial possibilities and understand if there's sense in continuing any talks.
"If there's no money, then there's no drive. I'm not prepared to hold talks all winter like last time."
