Rosberg joins Kubica's management stable
15 September 2017 – Reigning World Champion Nico Rosberg has revealed that he is to work with Robert Kubica in the Pole's bid to return to Formula 1.
Rosberg claimed the 2016 world title and shocked the sport by retiring just five days later, in order to explore new avenues in life.
Rosberg raced alongside Kubica in karting and junior formula, before the pair both graduated to Formula 1 in 2006 with Williams and BMW-Sauber respectively.
Kubica, though, suffered severe arm injuries in a rally crash in 2011, cutting short his Formula 1 career, before he began to explore the possibility of a comeback earlier this year.
He sampled 2012-spec machinery in association with Renault and was afforded the chance to pilot the manufacturer's 2017 car during in-season testing at the Hungaroring last month.
Kubica's prospects of returning with Renault, though, appear to have been ended by the impending announcement that Carlos Sainz Jr. will partner Nico Hülkenberg in 2018.
The 2008 Canadian Grand Prix victor is still pushing to make a return to Formula 1, and Rosberg has now joined his management stable.
"I'm excited to be working with Robert and his return to F1," Rosberg posted on social media.
"He and Lewis [Hamilton] were the fastest I raced against."
