Jenson Button makes qualifying better his priority for Canadian Grand Prix

The McLaren driver has started the last two grands prix from 10th and 12th positions as he has struggled to get the balance of his car right. Button has scored just two points in the last three events.

The Briton, the winner in Canada last year, says he is aiming to fix his qualifying problems this weekend as his main priority.

"Obviously, returning to Montreal will be an extremely proud and happy moment for me," said Button in a team preview. "This weekend, though, it's going to be important to get a handle on the car in qualifying.

"At the last two races, Q2 hasn't gone my way, so, no matter what pace you have in the race, you're still compromised on Sunday afternoon, particularly as the pack is so tightly bunched at the moment.

"My aim for the weekend will be to have a stronger qualifying performance and to be able to build on that in the race."

Team-mate Lewis Hamilton is also hoping for a change of luck in Montreal, the 2008 world champion still seeking his first victory in 2012.

"I know that the results we all want will soon come to us: I am doing everything I can to extract every tenth from the car, and I know that the guys at the track and the men and women back at MTC are doing everything they can to give me a car that's worthy of winning," he said.

"We are still very much in the hunt for this world championship and I'm looking forward to bringing that fight to Montreal, which is one of my favourite races of the season."
