F1 legend Gerhard Berger has admitted he is involved in Nico Rosberg’s negotiations with Mercedes over a new contract beyond 2017.
Earlier, the former Ferrari and McLaren driver was quoted as saying he recommended that both parties "renew the contract".
Now, Berger has confirmed to Germany’s Auto Bild that he is representing Rosberg in those talks.
"Keke (Rosberg) asked me if I would take over the negotiations for him," Berger said. "But this has nothing to do with a collaboration in the future.
"It is purely an act of friendship."
Berger and the Rosbergs’ relationship dates back years, including when as joint BMW motor sport director he arranged the now 30-year-old’s first F1 test for Williams.
Niki Lauda, Mercedes’ team chairman, confirmed the talks with Berger over Rosberg.
"I talked with him (Berger) already yesterday," he said.
"I have negotiated with Gerhard before, when I was a Ferrari advisor and he the driver. I am curious to see what comes of it now," Lauda added.
