Max Verstappen: "We thought it would be best to take the engine penalty here in Russia, we took everything into account before making the decision and we of course considered the weather for tomorrow. We had to take the penalty at some point so if we didn't take it here, we would have taken it somewhere else. As for the set up, we are trying to make the best possible race car for this weekend despite starting from the back of the grid. I hope it's going to work out and we will try to make the best of it during the race on Sunday, for now let's wait and see what the weather will be like tomorrow."

Sergio Perez: "I think we have some good information going into qualifying tomorrow, when there won't be much running due to the rain, so today was probably the last chance we have to test the dry conditions before qualifying. I think there is potential in the car for this weekend, we just have to make sure we get it right. I think my first and second sector looked good but there are some areas to improve in the third sector. There are some set-up changes we might need to make to the car to suit the weather conditions come qualifying but there are still a lot of interesting things to be analysed later on this evening. With Max starting from the back, it is going to be a bit of a challenge as a Team and obviously Mercedes are very strong around here but hopefully we are able to put some pressure on them and qualify very close to them, that would be ideal."
