Ross Brawn has once again dismissed speculation that he is on his way out, insisting he is responsible for "running the team on an operational level".
Rumours that Brawn is set to be replaced as Mercedes team principal refuse to go away and it increased on Monday after McLaren confirmed that Paddy Lowe will leave Woking at the end of the season.
However, Merc's non-executive chairman Nikki Lauda was quick to dismiss the reports saying "Ross is in his position and will stay in his position".
The 58-year-old Brawn has now also come out and denied that there are too many people in charge at Brackley.
When asked by the official Formula One website about the expression 'too many cooks spoil the broth', he replied: "Ha, it can be a problem if everybody tries to do the same thing! (laughs).
"It is important to have clear areas of responsibility. I am responsible for the sporting side; running the team on an operational level. If we can maintain that then there will not be a problem."
Brawn, who has won several titles with Benetton, Ferrari and Brawn GP, insists he is more determined than ever end his Championship winning drought which stretches back to 2009.
"I think it makes you more ambitious - hungrier to get back to that feeling that you had when you were successful," he said.
"Formula One is an incredibly challenging business and one has to be right on several levels to achieve success. We convinced Lewis (Hamilton) to join us, and we put in place a very good technical line-up during 2012 - and the car we've got now is reflecting that.
"It just takes some time to recognize what you have to do; that the corrections that you have to make and the solutions that you have to put in place are a 12- to 18-month process - in any team. Yes, it has been frustrating, but I genuinely feel that we are going in the right direction."
