Button looking forward to 'fun event'

Renault is heading to Indianapolis in confident mood following its double points score at Monza. Jarno Trulli headed Button as the pair took fourth and fifth places, the team's best result of the season.

"It's a fun event," said Button. "We don't go to the USA that often and it's pretty cool. I enjoy the whole weekend and the crowd means that the atmosphere is always special."

The Briton has outscored Trulli over the course of the season and hopes to retain his seventh place in the championship. "That's obviously important and I don't think it should be a problem," he said. "It would be great for me personally and is what I am aiming for."

Trulli is also excited about racing at Indy. "I enjoy being part of the myth of Indianapolis," he said. "The history of the track counts for a lot and it's always good to see some different supporters!

"We obviously have high expectations and want to end the season strongly. We need to wait and see how the car will react - we can't tell that until we get to the track - but I am very motivated and determined as ever to score more points for the team."
