Felipe Massa has said he knows who is replacing him for the 2018 season at Wililiams, but would not reveal the identity of the driver.

After the second attempt, Massa is retiring from Formula 1 following the Abu Dhabi Grand Prix this weekend as he stepped back into Williams car when Valtteri Bottas joined Mercedes.

But Williams are now one of the last teams to fully announce their 2018 line-up and are set to officially confirm the news after their post-season test next week.

Robert Kubica is the strong favourite to be announced as Lance Stroll’s partner, but Daniil Kvyat, Pascal Wehrlein, Sergey Sirotkin and Paul di Resta have all been linked throughout the long process of finding Massa’s replacement.
