WILLIAMS head to Russia this weekend hoping to continue their strong record at the Sochi circuit.

Valtteri Bottas finished third in the race's Formula 1 debut in 2014, while teammate Felipe Massa came fourth last year.

The Grove-based team have not claimed a top-four finish so far this season, but chief technical officer Pat Symonds is hopeful a return to Russia will provide a boost.

He said: "This is a circuit where we have been competitive in the past, and whilst the first three races have not yielded as many points as we would have liked, we hope Russia will see an improved result for us."
