Sebastien Bourdais has admitted that his future in formula one still hangs in the balance.

Bosses of the Toro Rosso team have said their decision about the 2009 lineup, with Sebastian Vettel moving up to Red Bull Racing, has been delayed until the end of the season.

Candidates including rookies Sebastien Buemi and Bruno Senna, and Japan's popular Takuma Sato, are in the frame for seats.

Bourdais, a multiple title winner of the now defunct American Champ Car series, has had a difficult debut season alongside Vettel, but at Fuji finished sixth and ahead of the highly rated German race winner.

He was furious when stewards subsequently demoted him to tenth place because of his collision with championship contender Felipe Massa.

Bourdais wrote in his latest column for France's L'Equipe that good results are "essential" to his chances of staying at the team in 2009.

"My team has not yet decided whether it will keep me next year," the 29-year-old confirmed.

Recently, he was quoted as urging Toro Rosso to make its decision.

"If there comes a certain time when they have not taken a decision, it may be necessary for me to take it for myself. I am neither hopeful nor anxious," Bourdais said.
