The 57-year-old German's career at BMW dates back to the late 70s, and he has overseen the carmaker's formula one and motor racing activities for more than a decade.

Mario Theissen insists he is still not ready to make a decision about his future.

The 57-year-old German's career at BMW dates back to the late 70s, and he has overseen the carmaker's formula one and motor racing activities for more than a decade.

But with BMW deciding to withdraw from F1 after Sunday's Abu Dhabi grand prix, Theissen has left open the possibility that he might stay on board at the Swiss BMW-Sauber team, which has been bought by the Qadbak consortium.

He told the German news agency SID: "I have always said that I will make a decision after the current season. Nothing has changed."

Theissen believes that BMW is not likely to make a swift return to formula one.

"When a company changes its strategic decision then this is always of some duration. You can't change strategy from one day to another.

"To say anything more would be speculation," he added.
