Williams need Kubica's "fighting spirit" to comeback from 2018 woes

After completing his own mega comeback, Claire Williams is asking Robert Kubica to give Williams some "fighting spirit' as they hope to bounce back from a disappointing 2018 season.

Kubica will complete his comeback from a life-changing rally crash when he drives out of the Williams garage as a Formula 1 driver in Australia. Last season Williams picked up just seven points over 21 races.

"Next year - is a new start for Williams and I spent a lot of time with Robert over the course of the year. I really enjoy his company, just his fighting spirit. We need that in this team at the moment," Claire Williams told Autosport.

"We need everybody pushing, and I think Robert is going to be a great addition for us for 2019 and beyond."

Williams faces a reshuffle next season as both Sergey Sirotkin and Lance Stroll walked through the exit door. British youngster George Russell will make his Formula 1 debut, but Kubica's role from 2018 will provide some important information for both drivers.

"One of the things that impress me most about Robert is the fact that he didn't get in the race seat for this year, yet he still took on the role of the reserve driver. That shows a lot about his personality," she added.

"He knows everybody in the team, he gets on well with everybody in the team, he's dedicated, he spends a lot of time back in the factory in order to help us drive our performance."
