Although no official announcement as yet, plans are said to be close to completion for Felipe Massa to return to Williams, leaving the way open for Valtteri Bottas to join Mercedes.
Massa has allegedly agreed to postpone his retirement for a year, allowing Bottas to join Lewis Hamilton at Mercedes following Nico Rosbergs shock retirement announcement earlier this month.
Bottas was apparently Mercedes boss Tito Wolffs first choice with Williams only agreeing to release him if an experienced replacement could be found.
Williams have also signed 18 yr old Canadian Lance Stroll, the Formula 3 European Champion will be the youngest driver on the F1 grid in 2017.
