Ross Brawn has denied there is any favouritism in the Brawn GP team following comments from Rubens Barrichello after the Spanish Grand Prix.
Barrichello had led from third on the grid in Spain ahead of Button, but the positions were reversed after the team took the decision to switch Button from a three-stop strategy to two-stops – while Barrichello remained on the planned strategy to stop three times.
With Barrichello also struggling with his third set of tyres, Button was able to get ahead and secured his fourth win in five races this season – extending his lead over Barrichello in the standings to 14 points as a result.
After the race, the Brazilian was quoted by American television channel SpeedTV
as stating that he would 'hang up his helmet tomorrow' if he 'got the slightest sniff' that the team was favouring current championship leader Jenson Button as it challenges for the 2009 F1 title.
Barrichello has already been embroiled in team orders issues before after being forced to play second fiddle to Michael Schumacher at Ferrari for a number of years, but Brawn insisted that his drivers comments had been 'overblown' in Barcelona and there was no issue between his men.
"We don't have a one and a two driver," Brawn told BBC Radio 5 Live
. "They're both on equal terms and conditions.
"Once he [Barrichello] got back and we talked things through he was fine. Rubens is a great team player. Everyone is working so well together and Rubens and Jenson recognise that. The fact we have such a great atmosphere drives us on and we don't want to lose that.
"We've been completely honest with the drivers. They know the situation and their engineers know that - there's no favouritism.
"Our plan is to give both drivers both equal opportunity unless there is a mathematical chance one can't do it. If one driver can do it and one can't then we would have to focus on that driver."
