Max Verstappen: "Today was maybe not the best of days, but in general it was okay. I like it here and I enjoy driving this track. We still need to find some time, but we did a lot of running, which was important to achieve. It will be a very challenging race on Sunday, that's for sure, because it's very hard for the tyres here."

Carlos Sainz: "I think we had a good first day in Brazil. We managed to complete plenty of laps, which was the main target for today as this is a new track for me. I must say that I really enjoyed it a lot out there, it's an interesting circuit! We were able to complete all of our programme without any issues. The only little inconvenient in the whole day was that our run on Option tyres in FP2 was spoiled because of the red flag. A bit of fine-tuning needs to be made for tomorrow, but overall I'm happy with today."

Phil Charles (Chief Race Engineer): "A bit of a difficult day for us today. The short runs didn't look to be our normal performance level so we know we have some work to do in this respect tonight. We did make some changes across lunch so we will dive in the data tonight to see if there is a direction or some clues in those changes that can help us. In terms of the long runs it looked like a lot of people were struggling with tyres after quite a small number of laps. On the positive side, I think we were not in as bad a situation as some in this respect, however, getting on top of the tyres for Sunday will be a big focus. Both the front and rear axle are not particularly happy so it will be quite an engineering problem to tackle."
