Sebastian Vettel is not concerned about the weather playing a significant role in this weekend's title decider.
The final race of this Formula One season could be an extremely wet one with thunderstorms forecast for Saturday's qualifying and heavy rain for Sunday's race.
The weather could play into the hands of Vettel's title rival, Fernando Alonso, as his Ferrari is no match to the RB8 in the dry but has won two wet races already this season.
Vettel, though, is very relaxed about the situation.
"I think in terms of general preparation we do what we can; weather wise... it's Sao Paulo," said the German during Thursday's press conference.
"It's the same as if you go to Spa, things change quickly and the weather changes a lot here.
"I spoke some locals and I think there was a big rain [storm] a few days ago which wasn't expected.
"Probably for Saturday and Sunday there is some rain on the way, but you don't know how much, or when.
"I asked Pirelli if they had all the containers here with the rain tyres, and that's the case, so I don't think we have to be concerned!"
Should it stay dry, though, Vettel is in the pound seats as he holds a 13-point advantage over Alonso and is expected to be behind the wheel of the more superior of the two cars at a track where Red Bull have won the last three seasons.
"The circuit seemed to suit our car in previous years. We need to confirm it this year.
"So all eyes on Friday to start the weekend to get into the groove. I think we can be as confident as we could in this stage. Obviously we know there is a lot ahead but I think we are in a great position."
