Jenson Button hopes his dreadful run of form will come to an end in the Canadian Grand Prix in Montreal this weekend.

The Englishman has scored points just once in the last four races, with his plight hitting a new low on home ground at Silverstone two weeks ago when he retired after starting 19th.

But he hopes to leave Honda's poor form in Europe and enjoy an upturn in fortunes for Formula One's North American double-header, starting this weekend in Montreal before the trip to Indianapolis.

He said: "Montreal is a great circuit and I really enjoy racing there.

"Our car seems to be well-suited to the track. It's a medium downforce circuit which requires much less wing than we have run in the last few races and the car seems to work well on that wing level.

"We've done some good work in testing and I'm generally pleased with the results, but we'll have to wait and see how things go at the weekend.

"The critical thing is to make sure we get the very best out of what we have."

Button set the fastest lap in testing at Monza last week and his team-mate Rubens Barrichello is taking encouragement from an extensive three-day test session.

He said: "We had a positive test last week in Monza and I think we should be able to have a good weekend."
