Coulthard will finish his drive with the McLaren team this weekend at the Brazilian Grand Prix. But he has made it clear that he wants to remain in the sport.

In a recent interview Coulthard said: "As we speak I don't have a contract to drive in Formula One next season, but there is a drive available at Williams and I think if there is a candidate available, my credentials are stronger than anyone's out there.

"I've got pole positions, I've won Grands Prix, and I've got a lot of experience of developing cars, tyre development. I've got to do everything I can to try and make them realise that I am the best of the drivers available."

Coulthard also indicated that he would not only be valuable to the WilliamsF1 team as a driver but through the sponsors that he would bring to the team.

He added: "It's been quite surprising the amount of interest from sponsors because over the last few years I've never had an outlet for that because at McLaren you don't carry your own personal sponsors and badges.

"I've been contacted by people wanting to know what my future is and if they can be involved. In terms of that sort of thing it is a pretty exciting time, it just takes a number of other people to believe and give you an opportunity."

Despite his desire to keep driving this weekends race could be his last, unless the WilliamsF1 team throw him a life line for at least the 2005 season.

Coulthard closed by saying: "You decide you are getting older because you've been doing this for a few years, but it is an exciting time. With uncertainly, if you have motivation to want to continue and then you get up and work and see what you can see. Obviously in this situation is not just down to your desire but we shall see what happens."
