David Coulthard believes he is the best candidate to take the vacant drive at Williams next season.
Williams have lost their battle with BAR to sign Jenson Button, while Coulthard's contract with McLaren is up at the end of this season.
"I think my credentials are stronger than anyone's," said the Scot, who made his F1 debut for Williams in 1994.
"I've got pole positions, I've won Grands Prix and I've got a lot of experience of developing cars."
He continued: "I've got to do everything I can to try and make them realise that I am the best of the drivers available."
Williams had signed up Button to partner Mark Webber next season, but BAR retained the Englishman's services by winning a bitter contracts dispute.
Coulthard will complete his 150th and final race for McLaren in this weekend's Brazilian Grand Prix after which his place will be taken by Juan Pablo Montoya.
Coulthard, who was linked which a move to Jaguar before owners Ford decided to put the team up for sale, faces competition from Antonio Pizzonia for the vacant Williams seat.
The Brazilian test driver impressed as a stand-in for the injured German Ralf Schumacher.
Meanwhile, Coulthard has urged F1 supremo Bernie Ecclestone and the British Racing Drivers' Club, owners of Silverstone, to come to an agreement to retain the British Grand Prix.
"It is a regrettable situation and I hope it can be
rectified so we can have a Grand Prix at Silverstone," said Coulthard.
"It is not the best drivers' circuit in the world but it is by a
long way better than some of the modern tracks we have raced on
recently from a drivers' point of view."
Brazilian driver Rubens Barrichello agreed that Silverstone should be kept on the F1 calendar.
"There are a couple of tracks that we should get rid of in the
calendar," he said.
"I wouldn't name them, because that would be bad, but
Silverstone isn't one of them.
"It's a circuit which is fantastic to drive and I would be very
sorry not to visit England."
