GROVE-BASED Williams endured a difficult weekend in a rain-soaked British Grand Prix at Silverstone.

Felipe Massa finished 11th and Valtteri Bottas 14th at the Northamptonshire circuit, with both drivers struggling in changing conditions.

Bottas, who qualified seventh, spun on lap ten to fall to 13th and never recovered as he struggled with the pace on the medium tyre in a race started behind the safety car.

Massa started 12th and made up places late on as others suffered with degradation.

The Brazilian said: “That was a disappointing race.

“We were trying to fight with so many cars throughout the whole race, but in the wet it was so tricky with oversteer.”
