James Key to Williams in 2018?

James Key has become the latest technical figure in Formula One to be linked with a move away from his respective team.

The Toro Rosso technical director is being linked with a potential move to Williams once his contract expires in 2018, where he will replace Pat Symonds who is set to retire.

Red Bull's motorsport advisor Dr. Helmet Marko did little to dispel the speculation of the former Sauber man's impending exit, telling Auto Motor und Sport: "It is possible that after his contract expires (in 2017), he will go to another team."

Meanwhile, James Allison, who left Ferrari earlier this season, is being linked with a number of teams.

Former team Renault is a potential destination, along with Williams, McLaren, and Red Bull, where there has been whispers of him potentially replacing Adrian Newey in some capacity
