Jenson Button is now set to sort out his future with Brawn GP after becoming Formula One world champion. The 29-year-old has confirmed he wants to stay with the team that has helped him achieve his lifetime ambition, but there are apparently doubts. Button's fifth place in Sunday's dramatic Brazilian Grand Prix guaranteed him the title with a race to spare as rivals Sebastian Vettel and Rubens Barrichello could only finish fourth and eighth. Now he can concentrate on organising his future within a team that also collected the constructors' title just over ten months after it appeared they were on motor sport's scrapheap. The main issue appears to be money with Button understood to be looking to return to the £8 million-a-year salary he previously enjoyed with Honda before taking a £5 million pay cut for this season to drive for Brawn. "I want to be here next year and I want to be with a team that can challenge for victories like this season," said Button. "Brawn can do that. These guys are not one-hit wonders. We've some sensationally talented people in our team."
