Ross Brawn: 'Michael Schumacher could leave Mercedes'

Ross Brawn has admitted that he faces a difficult decision over whether Michael Schumacher will remain at Mercedes beyond the end of this season.

Reports late on Thursday night suggested that Lewis Hamilton was ready to agree a move to Mercedes, throwing Schumacher's future further into doubt.

Team boss Brawn told Radio Five Live: "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.

"Michael has been a huge asset to the team, he's really taken us forward. I do think Michael contributes an awful lot."

A number of Mercedes officials are reportedly eager for Schumacher to retire.
