If Williams is serious about becoming a top team again, signing Jenson Button for next season would be an emphatic statement of intent.
With Kimi Raikkonen now confirmed at Ferrari for 2017, Red Bull all tied up and Mercedes almost certain to re-sign Nico Rosberg, Williams finds itself in the enviable position of holding the most desirable seats on the grid.
It marks a distinct change to 2014, when the team was limited in who it could get after a disappointing run of form. It kept faith in emerging talent Valtteri Bottas and signed the experienced Felipe Massa as it began the rebuilding process.
