Valtteri Bottas believes the returning
Robert Kubica will help
Williams get back to where they "deserve to be" following a dreadful 2018 season.
The British side finished 10th in the constructors' championship last year, with just seven points recorded by their two drivers
Lance Stroll (six) and
Sergey Sirotkin (one).
Bottas drove for
Williams in 2013-16 before replacing Nico Rosberg at
Mercedes and the team haven't been the same since his departure.
But next season brings more hope for Williams with a brand-new driver line-up, with Kubica being partnered by Mercedes youngster
George Russell.
"For Robert, it will be nice to see how it goes," Bottas said to Crash.net. "He's been out of racing for a while (eight years), so it will be nice to see how he compares to George Russell.
"I think for the team, that has had a tough team - and I know how difficult it is to keep up the motivation and the good spirit when things are tough - maybe a new drivers' line-up will bring more positivity and things to look forward.
"I'm sure they'll be full of energy, both drivers, for the great opportunity they're both having. Hopefully that will help put Williams where they deserve to be and not where they are now."
Kubica is making a long-awaited return to Formula 1, after a rally-car accident back in 2011 left him with severe injuries to his right hand.
