Jenson Button is refusing to let his head drop despite the Brackley-based Honda team sliding further off the pace of Formula One's top guns.

The 26-year-old was denied a point in Sunday's Canadian Grand Prix by David Coulthard's late passing move, which relegated him to a miserable ninth place.

Button has not scored in the last three races after Honda's form dipped so alarmingly they ousted Geoff Willis as technical boss.

But, despite the upheaval and the disappointments, Button is resolutely staying positive, insisting that is the only way progress can be made.

"I want it to get better," he said. "It's not going to move us forward if we are not motivated.

"What's the point in not being motivated? You have always got to be motivated in whatever you do. However bad things get you've got to be motivated.

"That's just my opinion maybe most people aren't like that."

The Englishman will head south to Indianapolis with little hope of an upturn in fortunes.

With only a few days before practice begins for the United States Grand Prix, Button can only hope lessons can be learned from his Montreal maladies.

He struggled with an unpredictable car and was several seconds a lap slower than race winner Fernando Alonso when the problem was at its worst.

He hopes Honda's under-fire engineers can find a solution, but concedes the odds are stacked against them with so little time before the next race.

"A lot of people in the team have obviously found this weekend tough and disappointing," Button added. "We'll look over the reasons for it and hopefully solve some of them for Indy next weekend.

"Words won't make us go any quicker, but Rubens Barrichello and myself are very pushy and it will make difference it has to. I don't know how long it's going to take.

"We just have got to make the most out of what we've got. It's really difficult, I don't know if we'll have the same situation as here.

"In Indy we have got to wait and see. Hopefully we can find something which can help us for Indy, because we don't have any different parts on the car.

"It's not an aerodynamic issue. It's something we need to resolve as soon as possible because it is costing us massively.
