Felipe Massa admitted his early crash caused him to struggle during the whole of Friday practice for the British Grand Prix.

After Susie Wolff had already stopped on track with an oil pressure problem, Massa soon crashed at Stowe to rule both cars out of FP1. The incident meant a number of parts Massa had used in Austria were damaged and he had to revert to previous versions, and he said the knock-on effect was a tough second session.

"It was for sure not a very positive day for me because of the crash," Massa said. "So I am very disappointed to have that crash starting the session. So I lost time in the second session and also I had to put some pieces on the car which were old-spec - which shouldn't be a problem for tomorrow, but it was today - and I didn't have a very good balance in the car as well.

"So it was not a great day for me. I'm sure things can be much better tomorrow and things can be more consistent as well to get the right balance and everything with all the pieces and everything set for the race. Maybe tomorrow will be completely different weather as well so we need to be clever about everything."

And Massa took full blame for the accident despite tricky conditions for the teams throughout Friday's running.

"It's very windy. For sure the wind didn't help but it's my responsibility. I just went a little bit wide on the exit of corner 15 and the astroturf just pushed me to the inside and I spun. It's really disappointing to start the session like that so thanks to the job from the guys that they managed to fix the car to run in the afternoon."
