Reigning World Champion Nico Rosberg has become part of Robert Kubica's management team as he looks to help the Pole get back into Formula 1.
Many wanted to see Kubica replace Jolyon Palmer at Renault next season, but Carlos Sainz has now been confirmed as the Brit's replacement for 2018 on an initial one-year loan.
However, it is looking increasingly likely that a seat is available at Williams as doubts linger over Felipe Massa's future, and Kubica has added Rosberg, who spent four seasons with Williams from 2006 to 2009, to his backroom staff.
"Excited to be working with Robert and his return to F1," said Rosberg.
"He and Lewis were the fastest I raced against."
Kubica added: "We have known each other since we were kids and he will be a great asset in my F1 comeback."
