Ross Brawn has played down speculation that friction has developed between himself and the Mercedes board after a difficult F1 season.
Having bought the title-winning Brawn GP team during the winter, Mercedes went into 2010 looking to fight for the championship but has been unable to match the likes of Red Bull, McLaren and Ferrari.
As a result, the team goes into the final four races of the season fighting for fourth place in the standings with its hopes of defending the championship crowns having ended a long time ago.
Rumours had suggested that the lack of a title challenge had left Mercedes questioning Brawn's future but he insisted there were no problems with senior Mercedes management.
“It's sad that such rumours always get around,” he told F1.com
. “But let's be clear - none of us are happy with the performance this year, and of course Mercedes want to know how and when we will improve. But nobody needs to tell me that it is important to win.
“We can probably still improve the relationship between Brackley and the Mercedes engine factory, but Mercedes is very open to all suggestions. So at the moment there are no problems whatsoever. They will come if we are not able to improve in the future.”
Brawn also dismissed talk that he could quit his role at the end of 2011, insisting that it would be 'too early' to end his F1 career.
“Next year would probably be too early,” he said. “I like this team. We have gone through many things together. I would never leave the team in an unclear situation. But I also don't want to do this job when I am 65 years-old. Bernie Ecclestone set the benchmark very high, true, but I don't think that I am as highly productive as he is!”
