Webber: Vettel chances are realistic

The Australian, who was in contention for the title in the middle of the season but dropped out after the Singapore Grand Prix where he crashed after suffering a brake failure, believes that Vettel could still overhaul championship leader Jenson Button.

Red Bull is also in with a shout of winning the Constructors' Championship, although would need to finish one-two in both the Brazilian and Abu Dhabi grands prix with Brawn not scoring to do so.

"The team knows it's a long-shot, but we're still in with a chance," Webber told AUTOSPORT. "This is F1 and anything can happen.

"Jenson has had a tough back part of the championship. There have been a lot of teams arriving at the front - Lewis Hamilton and all those guys. Different cars have operated well at different tracks and that's what has made it hard for Jenson to close the deal.

"I think that he has driven sensationally and I think if he is the world champion, he deserves it.

"We have scored a lot of points and Brawn have more than us, but it is still a phenomenal season for the team. There are still a lot of positives."

Webber has also clarified reports suggesting that he is unwilling to support Vettel's title bid, saying that he will do whatever he ca to help the team.

"If I can help Red Bull, of course I will," said Webber. "I was asked what would happen in a certain situation and what I could have said is that I will do whatever to help the team. But what I actually said was that I doubt the situation would arise - and I still do now.

"The race is long and to do a perfect grand prix for the right situation is not that straightforward. I that does happen, then we will do what we can do.

"But I am getting out of bed thinking about getting the best result for me because that's what I've got to do. If I can help Red Bull, I can do it."
