It's the comeback the whole of F1 wants to see happen - but reports are now suggesting Robert Kubica is not likely to be handed a drive for 2018 by the Williams team.
The Pole, who last raced in F1 in 2010 before a rallying accident curtailed his career, was thought to be leading the chase for the only seat on the grid yet to be decided.
He drove for Williams at the post-season Pirelli tyre test in Abu Dhabi after the final race of the season last month, and since then the team has been evaluating his data as they try to come to a decision.
But according to Autosport, Kubica is now no longer in the running for the seat at Sir Franks's outlet.
Instead, Russian racer Sergey Sirotkin is now understood to be favourite to land the drive.
The 22-year-old, who has spent the last two seasons as reserve driver for Renault, also tested for Williams in Abu Dhabi and Autosport claims talks are underway between him and the team as they look to finalise a contract for 2018.
Former Red Bull and Toro Rosso driver Daniil Kvyat is thought to be the back-up option, meaning Paul Di Resta and Pascal Wehrlein are out of the running.
Williams has yet to comment on who will line-up alongside Lance Stroll next season, but are hoping to make a decision before Christmas.
