Sebastian Vettel: "Although I have raced here many times, this circuit feels a lot different in these new cars. The main difference is that the tyres are much bigger so it is more difficult to see the track around you. The cars are also much stiffer and going through the tunnel is not as easy as it used to be. I was lucky to save the car during a mistake at the Swimming Pool, despite my heart rate definitely going up! We tried some new things today, so we need to see what worked well and learn how to fine-tune the set-up more. Tomorrow the key will be making sure we have a clean lap in qualifying, especially during Q1 when the track will be busy."

Lance Stroll: "It is great to be back in Monaco. Regardless of the car regulations, it is still the same track with the same corners and challenges. Today was a good opportunity to continue understanding the latest car developments and build on our experience in Barcelona. The tyres were overheating a bit in the hot weather, so managing the degradation will be a key part of the race on Sunday. As always, there are still a few things to work on, but I am confident we will make progress before qualifying."
