Max Verstappen: "It was pretty difficult but we knew coming into the race this weekend that this might be the case.

"There was a lot of bounce and temperature changes on track, which also made it tricky. Every time that we went over a bump, the car lost a lot of lap time and on this track one small jump could result in you ending up against the wall. We are looking into a solution ahead of the weekend to sort this out. In general, the issue is a bit more difficult to solve in set up and it won't be a quick fix but we are going to work on it overnight; we don't expect miracles but are still looking ahead to tomorrow. Ferrari are also looking quick but I am not thinking about that ahead of tomorrow. Overnight we are going to review the issues that we have and we will hopefully improve the drive of the car ahead of qualifying."

Sergio Perez: "It is going to be tough this weekend, we are finding it hard to get away from our limitations at the moment. We will see what we are able to come up with tonight, we ran a slightly different set-up on each car and I don't know what the issues were for Max until we debrief. There are plenty of things to look at, the long run pace seems to be in a better place, but we will have to wait and see how we perform tomorrow. Ferrari look really strong and whenever they need the lap, it has seemed really quick and easy. It is a benefit to them and they aren't struggling with their tyres either. We have a few items we need to be able to improve overnight and then hopefully it can put us back in the fight and we can be closer to the top."
