Monday 30 June at 10:41 : Sebastien Bourdais says he is trying not to worry about his uncertain future on the formula one grid.

The multiple Champ Car title winner, who is 29, joined the grand prix circus only this year, and has often failed to impress as much as his Toro Rosso teammate Sebastian Vettel.

Moreover, the future of his Faenza based employer is very much in doubt, after Red Bull mogul Dietrich Mateschitz signalled he is looking to sell his 50 per cent share.

But in interview with ITV, Frenchman Bourdais said he is trying to simply focus on 2008.

"Obviously if you start looking at this then you can get worried, so there are two attitudes to this.

"You can completely disregard it, which is pretty much the approach I choose to adopt -- after all, we've only had eight races so we're not even mid-season yet," he said.

"I can't really say I feel that I've shown what I wanted to show this year so far.

"What happen will happen. If I get fired because of this or because of that then so be it.

"What's really important for me is that I give my best. And I am giving my best, even if it's not paying off right now.

"But you can only influence so many parameters, so I will have no regrets, that's for sure. I'm doing the very best I can, and if it's not enough in some people's opinion then fine."

Bourdais said he hopes he can extend his formula one career into 2009, when the sport switches back to slick tyres -- with which he so dominated throughout his American career.

"Right now I'm focused on 2008. I can only hope I'll be able to show what I can do with a car that has slick tyres," he added.
