Jenson Button will hope to take a big step towards the F1 title this weekend as the Briton heads for Interlagos and the penultimate race of the season.
The Brawn GP ace remains the hot favourite for the title with a lead of 14 points going into the final two races of the campaign.
However, with team-mate Rubens Barrichello and Red Bull's Sebastian Vettel still in contention for the crown, Button goes into the weekend well aware that he can't afford to relax and the Briton admitted he was ready for the challenge of a vital weekend for the his title hopes.
"This year will be the first time for a while that we've been to Sao Paulo for the Brazilian Grand Prix when it hasn't been the final race of the season but it's still going to be such an exciting weekend,” he said. “There's always a great atmosphere at Interlagos and the Brazilian fans are so passionate about motor racing and particularly Formula One. Interlagos is quite an unusual circuit and it's an enjoyable challenge for the drivers.
“It's an important race for me and for the team in terms of the Championships and we will be working hard to get the best results possible from the weekend. It's going to be a challenge but one that we are all looking forward to."
