Recent reports suggest F1 team Mercedes are looking to replace team principal Ross Brawn. New executive director Toto Wolff has agreed a deal to bring in McLaren technical director Paddy Lowe.
McLaren have refused to comment on the situation.
On Tuesday afternoon Wolff said in response that he "hoped Ross was going to stay". But he would not be drawn on whether Brawn would be replaced as team principal."
"I admire what Ross has done but I need to understand the structure and what Ross has done," he said.
"At this stage it would be foolish to come in and speak about replacing anybody.
"There is speculation which is coming up in some of the media."
The planned restructure at Mercedes would leave no obvious place for Brawn or chief executive officer Nick Fry, the two men who in the winter of 2008/9 saved what has become Mercedes following the withdrawal from Formula 1 of then-owners Honda.
Brawn has insisted that they had been hit by a technical reshuffle that impacted on their attempts to develop last year's car and has said that he believes the right structure for success is now in place at Mercedes.
