Williams development driver Robert Kubica has revealed that Nico Rosberg is no longer actively involved with his management team.
The 2016 world champion lent a helping hand to the Pole during his F1 comeback efforts last year which yielded a reserve and development role with Williams, although Kubica and his management team had been targeting a full-time drive with the Grove-based outfit.
Rosberg and Kubica share a friendship which goes back to their days in the junior formula of motorsport. While no longer working together, the two men remain in contact.
"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. It is just that this period was very intense and now it's a completely different situation.
"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."
Kubica said that if circumstances change in the future, he could once again work with the former Mercedes star.
"It doesn't depend only from my side," he added.
"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."
