Jenson Button says wet Brazilian GP would increase risks for both Vettel and Alonso

Jenson Button has warned Sebastian Vettel that a wet Brazilian GP would "really mix it up" in his battle to see off Fernando Alonso for the Drivers' Championship.

The ever-tense spectre of a final-race title showdown has already been heightened at Interlagos by the ominous weather forecast for race day, which suggests heavy rain will hit the Sao Paulo region throughout Sunday.
Button's own title-winning weekend in Brazil three years ago was almost derailed when struggles in a rain-hit qualifying session left him well down the grid and the McLaren driver admits a wet Sunday would be a real step into the unknown - particularly for the two remaining title contenders - if the first days of the grand prix weekend are dry.
"It's really tricky for us to try and get a set-up for Sunday because we're not going to drive in the wet probably until Sunday," Button told Sky Sports News' Rachel Brookes.
"For us it's tricky but there are two people who are going to find it even trickier - Sebastian and Fernando. What a great championship decider to have these guys fighting it out and in the wet as well where there is so much risk involved."
Indeed, the 2009 World Champion reckons a wet race round the undulating circuit would immediately increase the chances of one of the title contenders not finishing, a prospect he says would alarm points leader Vettel in particular.
Asked by Rachel which one of Vettel and Alonso he felt would be feeling more pressure after both contenders had brushed off potential concerns to the media on Thursday, Button replied: "We all know the truth don't we - that isn't the truth from either of them!
"There's a lot of pressure on the guys, and they put it on themselves. That's the way it is, you want to win. If it's dry here I think it's pretty easy for Sebastian if they don't have reliability issues.
"If it's wet, which it probably is going to be, it's really does mix it up. It doesn't matter where you start, there's a massive risk of not finishing the race. Rather than being the quickest guy out there, it's not finishing the race which is the scary part for Sebastian."
