Nico Rosberg has refused to be drawn on whether he is really contemplating a switch from Mercedes for 2017.
Italy's Corriere della Sera claims that talks between the championship leader and Ferrari are underway.
When asked about that as he departed the Barcelona test, Rosberg said: "I feel very good at Mercedes, but let's see what the future holds."
A move to Ferrari would create a German 'super team' at the very Italian Ferrari, and Rosberg said that his relationship with Sebastian Vettel is "normal".
