The 32-year-old spent six seasons driving for the German constructors in F1 after joining them from pit-lane rivals Williams.
And he won his only ever World Drivers’ Championship with them last year before making the shock decision to quit the sport.
Rosberg didn’t leave Mercedes altogether though and continued to work for them in an off-track capacity.
The German has now discussed potentially signing a new deal to continue as an ambassador and whether it will impact his criticism of them as an RTL pundit.
“My contract as a team ambassador expires at the end of the year, so I will be totally independent,” he said.
“It may be that I will become a Daimler [Mercedes shareholder] ambassador next year, but that will not stop me being completely neutral and commenting critically on the races.
“Niki [Lauda] managed to do it as a member of the team, so in my situation I can as well.”
Rosberg follows in his father’s, Keke, footsteps by going into F1 punditry.
And his first race in that role will be the 2018 Australian Grand Prix.
Mercedes will be looking to defend their World Drivers’ Championship and Constructors’ Championship titles next year.
