Valtteri Bottas: It was nice to be back in the car after the break. Today our main focus was on aero testing, including the rear wing configuration and we also looked at the tyres as you would expect from a Friday. We collected plenty of data throughout the day so we know that today's times are not too representative, and we will continue to strengthen our performance throughout the weekend.

Felipe Massa: It was a typical Friday for Williams, we don't go out trying to top the time sheets. We completed a lot of the work we had set ourselves, only held back by the red flags which were unexpected. This has meant my long run pace isn't as clear as I would have hoped, but we should be able to be competitive tomorrow and build as the weekend progresses.

Rob Smedley, Head of Performance Engineering: We have had a decent Friday. We had set ourselves an ambitious programme to complete and although the red flags hampered this slightly we are very well prepared for the weekend. We focused on rear and front wing development during the morning and this afternoon was all about tyres. We still have a bit of time to find on the low fuel, but we know where to find this. On the higher fuel loads we look quite competitive. There are lots of small areas where we can find performance, so everyone needs to ensure that they have done their job to be ready for FP3.
