Brazilian GP: Helping Sebastian Vettel not on Mark Webber's mind

The Australian outqualified the German and they will start from third and fourth places respectively. Vettel's championship rival Fernando Alonso qualified down in eighth position.

Webber believes the best he can do in the race is to focus on trying to get the best possible result.

Alonso needs to outscore Vettel by 14 points to be champion, meaning he has to finish at least third.

"I think we focus on ourselves tomorrow and do the cleanest race I can. We know there is some tricky weather today," said Webber.

"I will be focusing entirely on my own cockpit."

Webber admitted it will be vital to react properly to the circumstances if the rain hits Interlagos as expected.

"We know Interlagos can be very hit and miss. A little shower can generate from everywhere and surprise you. We could run all three types of tyres - wet, slicks and inters.

"We need to keep our eyes open tomorrow. That is what can happen. Whatever it is, it will be a good final grand prix of the year and I am looking forward to a good result."
