Robert Kubica says 2016 Formula 1 world champion Nico Rosberg has taken a step back from being part of his management team.
Rosberg took an active role in helping lead negotiations for Kubica with Williams as the team pondered a replacement for Felipe Massa.
In the end, Williams opted for Sergey Sirotkin and Kubica was handed a reserve driver role for this year.
With the situation having been settled, and Rosberg working on other business activities that includes investment in Formula E, Kubica said the pair’s working relationship has changed.
“We did have a close work together at the end of last year, and we are in a good relationship, but for now, because I am doing what I am doing and he is very busy and he has his family, we are not working as close as we were last year, ” Kubica told Autosport. “But we are still in touch.”
Kubica has made it clear, however, that it was not the case that Rosberg and he had formally split – and that it was only ever really intended for the German to help with the specific talks at the end of 2017.
“It is just that this period was very intense and now it’s a completely different situation,” added Kubica.
“It is not a situation that Nico has been working and now is not working. It is just that the situation is that he is not as present as he was.”
When asked if it was possible that he and Rosberg could work again on projects in the future, Kubica said: “It doesn’t depend only from my side.
“A lot will depend on the situation and also it is kind of new everything for me to be back in paddock.
“So we will see what the future will bring and then we’ll move on.”
Kubica has retained his ties with long-time manager Alessandro Alunni Bravi, who continues to represent him on the legal and administrative front.
