Sébastien Bourdais' manager, Nicolas Todt, admits the French racer and Scuderia Toro Rosso driver is not yet guaranteed a future on the F1 grid beyond 2008.

Todt, who also handles the career of title contender Felipe Massa, told the French language 'RMC' that he is seeking to have the 29-year-old's contract extended to include next year.

"In Formula 1, whether it is your first or your tenth year, you always have something to prove and you are always judged on your most recent races," Todt, the son of former Ferrari boss Jean Todt, said.

"Right now, Sebastien's future in F1 is not yet assured, but I have a good feeling that he can stay at Toro Rosso," he added.
