Bernie Ecclestone believes Williams should not hesitate to pick Robert Kubica for a race seat in next season's F1 championship.
Ecclestone, the former chief executive of Formula 1, has been following Kubica's progress closely since a rally accident in 2011, and thinks the Pole could be the perfect driver for struggling Williams.
Kubica completed a test drive for Williams at Silverstone this week ahead of another run in Hungary next week while he competes for a race seat against Paul di Resta and Williams' current driver Felipe Massa.
"If Robert had not have had his accident, then I think by now he would have been world champion anyway, I think he can come back even stronger than before," Ecclestone told Autosport.
"Mentally, I think probably he will be more aggressive than he was then: so I can only see good, good things for him....I don't think his injury will hold him back."
Ecclestone believes that the Pole could become a popular figure in F1 if he returns, with huge potential gains, both on and off the track, for Williams if he ends up driving for them next season.
He added: "If he does what I think he is going to do - be even better than before - then people will get behind him, He will be good to have for Formula 1.
"If I were Williams, I would definitely try to persuade him to join. Maybe they are going to lose Felipe Massa at the end of the year, I should think he has probably had enough, and if Robert is on board then he might wake up a lot of people there.”
Ecclestone then continued to comment on the state of underperforming Williams, who sit 81 points behind fourth-placed Force India in the Constructors' Championship.
"The team hasn't been performing as well as it should have done, and whether it is because of drivers or the team in general, I don't know. Nobody knows. So it would be nice to get a guy who should be quick in the car to find out."
