"We'd gone into the day hoping to be able to start on the UltraSoft tyre and hoping for the front row so naturally we're delighted with the way that Qualifying went," explained Trackside Engineering Director, Andrew Shovlin.
"We had quite a few changes to the cars overnight and looking at our pace in the practice session today, we seemed to have moved in the right direction. We were certainly happier on the hot track than we had been on Friday.
"We were surprised by the pace on the UltraSoft in the second part of Qualifying. We'd thought it would be really tight to go through but as it happened, Lewis had nearly 1.3 seconds in hand, so the car is clearly working nicely on that tyre and hopefully that will carry into the first stint tomorrow.
"The HyperSoft is a bit trickier, even though the track is quite cool in the evening sessions it is still difficult to get the tyre to last the lap without overheating in the final sector. Both drivers did good laps in the final session and it was great to see Valtteri get back onto the front row on his final run and Lewis take another brilliant pole position.
"We know that we've still got a lot of work to do to win tomorrow and that Red Bull and Ferrari will be doing everything they can to take it from us, but we will keep pushing until the last lap of the season and hopefully finish the year in style. I also want to say congratulations to George Russell for his F2 title - well done, George!"
