Non-executive chairman Niki Lauda has admitted that Ross Brawn's future at Mercedes is in the balance, stating that it is currently 50/50 as to whether the team principal will stay next year.
Reports earlier this month suggested that Brawn could be set to leave the Brackley-based team to be reunited with Honda at McLaren
, while he has also been linked with Williams in recent months.
Brawn's future has been the centre of much speculation this year after both Toto Wolff and Paddy Lowe joined Mercedes, with Lowe being viewed by many as the long-term replacement for one of the most successful designers in recent F1 history.
Speaking the Mirror
, Lauda revealed he was keen to keep Brawn with the team for 2014, but said the ball was in his court as to what decision he takes.
"It's down to him now," he told Mirror Sport. "I'd say it's 50-50.
"We have had some small problems in the team in the past but everything is sorted now. It's all agreed between him and Paddy and everyone else.
“He's number one. I have tried to persuade him to stay. I want him to stay. We will talk again at the end of the season."
According to the report, sources have suggested that Brawn could elect to walk away from F1 altogether rather than seek opportunities elsewhere.
