Rubens Barrichello could stay at the Brawn team next year, despite expectations he had already penned a deal to switch to Williams.
The Brackley based team will almost certainly keep Jenson Button on board for 2010, but it was thought 37-year-old Barrichello's place would be filled by Nico Rosberg.
But to Brazil's SporTV, the Brazilian said he was "surprised" by some of the behind-the-scenes developments during last weekend's Interlagos event.
"I have the possibility of being with Brawn and also with others," Barrichello said.
However, a report in Spain's AS sports newspaper said Barrichello suspects Brawn altered his tyre pressures after leading until the first pitstop last Sunday.
