Vettel still optimistic about title

The Red Bull driver took his fourth win of the 2010 season at Interlagos, leading team-mate Mark Webber to another one-two for his team.

The result left Webber eight points behind championship leader Fernando Alonso, with Vettel still 16 behind the Spaniard.

Alonso need second place in Abu Dhabi to secure the title, or third if Vettel wins and Webber is second.

Despite the gap to Alonso, Vettel believes the title is still possible.

"I think so. If it was 26 it would be impossible, but 16 is possible," said Vettel. "I don't wish anything bad for him [Alonso] but I wouldn't be sad to see some Ferrari smoke.

"We are racing and pushing ourselves to the limit, I have to focus on myself, get the best out of the car, and try to repeat and try to win the race there and then we see where he is finishing or probably not In a week's time we will know."

Today's result clinched the constructors' championship for Red Bull Racing, the first for the Milton Keynes team.

"I think it's an incredible day," Vettel added. "Pretty incredible."
