Ross Brawn is not ruling out another return to Formula One.
The highly respected former technical chief and team boss has been causing a stir this week with excerpts of his new book making their way into the press. One blamed his departure from Mercedes on the team's management trio of Toto Wolff, Niki Lauda and Paddy Lowe.
"I was surprised," Wolff told the Telegraph in Austin, "because it was not at all how my conversations went with him.
"The whole situation was much more complicated than just trust," he explained. "The board felt there needed to be change in the way the team was run. Succession is always a sensitive topic.
"But my respect is still where it was for him. The book hasn't changed that," Wolff added.
Now there are rumours linking the former Ferrari and Honda man to a sensational move to McLaren.
The speculation follows talk of Ron Dennis leaving the Woking operation, and Eric Boullier also following him out of the door, amid links to Ferrari.
"We can confirm that Eric is 100 per cent committed to McLaren and not in talks with Ferrari or any other team," a McLaren spokesman insisted.
But Brawn, 61, has now told Germany's Bild newspaperisn't ruling out an F1 return.
"I miss some parts of my life in formula one," he said. "The teamwork, the spirit and the development of a team and the car."
When asked if he can imagine coming back to F1, Brawn answered: "Never say never."
