Simple question really.
Jenson is ready to start his contract talks with Brawn Gp. Now if you were in his place what do you do?
Its become clear the Brawn car has dropped off from the start of the season. They do not have the time and money backing that they had last year from Honda. So why would Jenson as a world champion not want to look elsewhere?
Ferrari and Mclaren have been by the numbers the two highest scoring cars in the 2nd half of the season, Mclaren started from scratch and built their new car with the plan to develop for next year. Ferrari gave up on this years car a while back and started again for next year, so you have to believe those two teams will be strong again.
Jenson might want to keep his eye on the second seat at Mclaren, Kimi is still no where near being signed up and I'm sure Mclaren would love an all british line up made up of the previous two champions, plus they keep the 1 on their car.
There is also Toyota, Renault and possibly a red bull seat, (webber is apparently not safe if a big name were to become an option) All those teams have shown they are capable of fighting at the front.
Brawn needs to hope he has a big cheque book or a generous sponsor, or else he's going to be left with Nico Rosberg and an empty second seat, in a car that wont start next season with a 2 second a lap advantage.
