Ross Brawn is comfortable with how Jenson Button and Rubens Barrichello are performing, and sees no reason to introduce team orders as the final two races of the season approach, and the chances for Sebastian Vettel to upset the Brawn GP fans diminish.

"This is as good as I've ever seen it in terms of two drivers trying to win the title," said Brawn. "As for team orders, that just simply does not apply. I think the two drivers of the calibre we have got, you cannot separate one out unless it becomes mathematically impossible to win."

Jenson Button currently leads team mate Rubens Barrichello by 14 points, with 20 points still available. Red Bull's Sebastian Vettel lies just two points further back, meaning a fifth place finish for Button would be enough to put Vettel out of the title hunt.

McLaren boss Martin Whitmarsh isn't certain that Button will remain in the lead come the end of the Abu Dhabi Grand Prix. "Jenson is under a lot of pressure and when you have not won a world championship there is enormous pressure there, especially if it is your team-mate who is challenging you," explained Whitmarsh. "It's very easy to crash out at the next event with Rubens winning, which will be a 10 point swing - and we've been there, the last two seasons have been like that for us. He has to stay calm."

Ross Brawn, Jenson Button and Rubens Barrichello will be keen not to repeat McLaren's recent history.
