David Coulthard is determined to carry on in Formula One and has confirmed his interest in joining the BAR team.
Coulthard wants to keep racing
The Scot has been racing for 11 seasons but loses his McLaren seat for 2005.
"I am highly motivated to continue racing," said Coulthard. "I was surprised to see some of the internet sites questioning how much I want it.
"I don't have a wife or children - I don't have anything else in my diary. There really is nothing else to get out of bed for."
Button will move to Williams at the end of the season providing his current dispute with BAR can be resolved and that has opened a new door for 33-year-old Coulthard.
"All the seats that are available we have targeted," added Coulthard.
"BAR's performance this year has been fantastic, there's no reason to expect it to be any different next year.
"I can understand Jenson's desire to go to Williams but at the moment BAR are doing a better job.
"They've done a fantastic job under David Richards' leadership and there is absolutely no reason why they can't build on that.
"I want to be in a competitive drive and have an opportunity to enjoy what I love doing, which is getting out there racing, irrespective of whether it's a foregone conclusion if you are going to be on the front two rows or not.
"If you can push yourself and the package then it's the same deal.
"There's naturally only so many seats available and in time we'll find out whether there's one available for me."
Coulthard has six races left this season to persuade potential employers of his abilities, starting this weekend in Hungary.
