Williams will wait until January to confirm who will drive alongside Lance Stroll in the 2018 season.
The replacement for the retiring Felipe Massa has prompted much speculation over recent weeks, with Williams continuing to delay a decision on their second driver.
Sergey Sirotkin is believed to be the favourite to take Massa’s spot after he impressed in the end-of-season testing in Abu Dhabi.

But Robert Kubica has also been in the running, as he eyes a return to Formula 1 – six years after suffering a career-threatening crash – while Daniil Kvyat is in the frame too, despite being dropped by Toro Rosso.
Williams have pledged to take their time over the appointment though after a spokesman confirmed that the team “don’t plan on any driver announcement until January”.
Kubica’s camp clearly still believe it is an open race after his father, Arthur, told the Polish press on Friday that they are harbouring hopes of a return with Williams.
“We’re still fighting to get Robert into Williams,” he said.
“We are taking steps to convince them to believe in Robert.”
