Daniel Ricciardo: "I'm happy with today. This morning was solid and the long run pace was good. We made a few changes in between the two sessions and look pretty good for now so hopefully we'll stay like that. On our long run pace we look like we're able to match Mercedes, possibly quicker, so if we get the pace we had today against Mercedes on Sunday it's going to be a fun race. It is only Friday though so let's see what they're doing tomorrow but it's nice to start the weekend on the right foot. I don't think we've got hours and hours of work ahead of us. Just a little bit of fine tuning as always but we don't have to search for too much at the moment."

Max Verstappen: "We tried some different setups from FP1 and FP2 to try and find a strong feeling with the car. In the end we found a good one for the long runs on soft tyres but we still need to improve the short run pace. I'm quite confident we can do that tomorrow. We got some good data from the short runs but struggled to find a clean lap. We changed the setup during FP2 in order to improve some issues, which is why my car was worked on for a while. The supersoft seemed to lose grip every lap and get slower, so I think for the race it will be interesting. The long run pace seemed good, I had a Ferrari in front of me and I was catching it so I think that is a positive sign."
