SEBASTIAN VETTEL

SAO PAULO (Reuters) — Red Bull will feel far less pressure than Brawn's Jenson Button and Rubens Barrichello in Sunday's Brazilian Grand Prix, according to Formula One title long-shot Sebastian Vettel.

''The only thing I can do is win,'' the German, who is 16 points adrift of Button and two behind Barrichello with two races to go, told a news conference on Thursday.

''The pressure is on the two people in front of me.

''For me it is pretty straightforward. You don't have to be a genius to work out that from now on we simply have to win the two races and hope that those two mess it up.''

Vettel, 22, won this month's Japanese Grand Prix to roar back into the reckoning after five non-scoring races in the 15 to date.

The wet conditions expected at the weekend could also favour the Red Bull, although Vettel's engine reliability could be suspect.

Brawn need only a half a point to be sure of the constructors' championship while Red Bull must aim for a one-two finish and hope Button and Barrichello fail to score.

Vettel said Red Bull had ''another couple of things in the bag'' in terms of development of the car, with a new type of front wing available and offering a potential step up in performance.

''This circuit should suit us. You still have a lot of corners where you need the downforce and it seems that is our strength, so we are looking forward to it,'' he added.

''On the other hand, you don't really know what to expect as this year has been very much up and down. You have seen different teams at the top.

''It's a good thing not to have the situation they (Brawn) are facing, they have to race each other,'' said Vettel, whose own Australian team mate Mark Webber is out of contention for the title.

The German expected Webber to do what he could to help him on Sunday.

''We are working together hand in hand and I think if the situation should come up, then I think he is the last one to deny any help,'' he said.
