New F1 champion Jenson Button wasn't the only happy driver in the paddock following the Brazilian Grand Prix after Mark Webber secured his second career win in the penultimate round of the 2009 season.

Webber had gone into the weekend looking to return to the points after a poor run of form and was also seeking an end to a disappointing run at Interlagos - a circuit he admitted he enjoyed but which had never delivered results.

The Red Bull man qualified on the front row of the grid alongside Rubens Barrichello and remained close to the Brazilian through the opening stint of the race before jumping into the lead following the first pitstops.

From that point onwards, Webber was barely troubled out front as he picked up his second victory of the season and he admitted it was nice to be back on the top step of the podium.

"I'm happy with that!" he said. "You never know in the first stint of a race what's going to happen, although I knew Rubens and Robert [Kubica] were a bit shorter than me. I was matching Robert's pace to start with and when they made their pit stops, I knew I had a clear run to make a gap to start my second stint. I just cleared Jenson on my outlap, which was good too.

"I was just making sure the tyres were comfortable for the whole stint. I was a little bit panicky in the second stint as Robert started closing, although my pace was not too bad and I knew he was quite short in the middle stint. I was then able to control the gap to Robert and he backed off towards the end, which gave me a nice run home. It's fantastic feeling to win again."

While rivals Brawn duly wrapped up the constructors' championship in the race, Webber's victory and fourth for team-mate Sebastian Vettel secured second in the standings for Red Bull and Webber was quick to praise the team for its stellar 2009 campaign.

"As a team we've had quite a few victories this year off the back of some tough seasons, but today has confirmed second place for us in the constructors' championship," he said. "We're very proud of what we have achieved this year as a team - I want to thank Renault as well, the engines have been very good and they're not easy environments for them to work in.

"Congratulations to Jenson and also to Brawn on clinching the championships today after a good fight. It was a good weekend for the Australians, as Jason Crump won the World Speedway Championship last night. He's a close friend of mine and he won it under difficult conditions, so a good weekend."
