Michael Schumacher talks with Mercedes still ongoing, says team principal Ross Brawn However, there has been no word from Mercedes, and unlikely to be for another few weeks at least, according to Brawn, as talks continue with 43-year-old Schumacher over his future. "It's still under discussion, I'm afraid," said Brawn on BBC Radio 5 Live. I can't comment very much on that, but Michael's been a huge asset to the team, he's really taken us forward. I do think Michael contributes an awful lot, so I think the decision for Michael to stay or not continue is a difficult one. Obviously he's very involved in that decision, and discussions are ongoing at the moment. Asked whether Hamilton could be joining Mercedes, Brawn naturally ducked the issue, adding: "I think any ambitious team looks at the top drivers and we're an ambitious team. But I think there's an awful lot of speculation. We will have some things to say in the next few weeks, next few months, and then all will become clear.
