Felipe Massa: It's always the job of Friday practice to understand the tyres and the track. It's a difficult track here and today was not so different from what I expected, and very hot. Now we need to analyse everything to improve our performance for qualifying tomorrow. We know the teams around us are very competitive here, maybe even closer to Mercedes than usual.

Valtteri Bottas: The car felt good today, we were able to find a good balance. We tried the option tyre, which was a bit of a struggle for us today, so we need to analyse how we can get a bit more out of it tomorrow. The long run felt consistent tonight, so the main thing to work on from today is the option tyre.

Rob Smedley, Head of Performance Engineering: We've got a bit of work to do on both the low and the high fuel. The drivers are alternately happy on the prime and the option tyre, so we need to work to get them each happy on both compounds. The reality is we need to find a bit of performance as well. The up sides are that we've brought a lot of new parts here, worked through our programme diligently, and they seem to be working well. Now we just have to put everything together to ensure we get a good position in qualifying.
