Ross Brawn has said that his team are still in discussions with both Jenson Button and Rubens Barrichello about 2010 – and that the line-up for next year is a 'work in progress'.
Button has shined this season and currently leads the drivers' championship, however with no deal yet confirmed the Brit could still move elsewhere. Although that is believed to be extremely unlikely, Rubens Barrichello position is far more precarious.
Indeed after his outburst after the German Grand Prix, when he claimed the Brackley-based operation had 'lost him the race', the Brazilian may well find this season is his final at the pinnacle of the sport.
Speaking in the official FIA press conference on Friday though, ahead of this Sunday's European Grand Prix at Valencia, the eleventh round in the 2009 F1 World Championship, Brawn refused to confirm what the situation is with his drivers for next year.
"It is a work in progress. I am sorry but we are in discussions with our drivers," Brawn told reporters. "We are obviously very happy with their performance this year and it is not appropriate for me to talk about what we are doing with our drivers at the moment. But we will announce it in good time what is going to happen."
Meanwhile, Button and Barrichello both seemed to be back on the pace in practice on Friday, ending proceedings second and third fastest overall. Asked about the team's recent troubles and their lack of form relative to the competition, Brawn insisted that there was nothing wrong with the car.
"To be frank it is just tyre temperature. Obviously in these sorts of conditions we have no problem generating the tyre temperature," he explained. "We did some scans of set-ups we have used in the last few races and all of them to be honest were very bad. Some were better than others.
"We did a couple of aerodynamic comparisons on pieces which we have tried and I think we have seen some differences, nothing that would necessarily be the reason why we have struggled the last few races, so I think the main issue is that here we are generating tyre temperature and the car feels good.
"The car feels as we have had at previous races. We have just struggled at the last few with tyre temperature which is still an issue which we will have to find a solution for as we have got Spa coming up and we have got some races towards the end of the year.
"But we are very pleased with today. We did some very good race work and both drivers are happy with the cars. It was a good Friday - but we had a good Friday in Hungary but then it got a bit more difficult the rest of the weekend. But I think the reason there was the drop in ambient temperature on the Saturday and Sunday whereas here the forecast is for it to stay hot or perhaps even hotter for Sunday. That's the predominant reason.
"No magic switch has been turned. There was nothing horribly wrong with the car. We had a logical programme today and I think we have understood some things and we are pleased with what we did."
