Three names have made the final list to drive for Williams F1 Racing in 2018.
Motorports.com is reporting that Robert Kubica, Felipe Massa and Paul di Resta are the focus of Williams, but that a decision is not expected quickly.
Kubica, who has driven for Renault Sport F1, is set to test for Williams in the coming weeks. Massa and di Resta are known quantities to Williams, with Massa already driving as a replacement for Valtteri Bottas and doing a respectable job. Di Resta has been a reserve for Williams, but not had a regular F1 ride since 2013.
Williams Racing is considered one of the premiere rides open for 2018 and, with not many teams having open rides, can take their time being selective. Whoever gets the nod will ride alongside Lance Stroll. One criteria for the slot that has factored in the decision - Williams arrangement with title sponsor alcohol brand Martini dictates that one of the drivers must be over the age of 25.
