- Did the SuperSofts not show to be as fast and reliable on Friday during practice? And if they did why was it not ideal to start on the UltraSofts to gain an advantage then switch to the SuperSoft that apparently just kept getting better throughout the entire race?
AS: "What we'd seen on Friday was that the Ultra was actually quite a weak tyre in Baku. I think that was a surprise for a number of teams. But we were seeing some abrasion on the fronts, where it starts to tear and open up, losing grip.
"You also saw some teams had a bit of damage on the rears. But, the net effect of that was that through the stint you were losing a bit of grip.
"Those teams that were fast enough to get through Q2 on the SuperSoft chose to take it. We saw that with Ferrari, Red Bull and us. Kimi (Räikkönen) had the issue where he locked up and scrapped that set, so he had to start on the UltraSoft.
"The concern with the UltraSoft was the degradation would bring you in early and you would lose control of the race. That's why the front teams were choosing to start on the SuperSoft.
"At the time, I think most people were thinking it would be SuperSoft and straight onto the Soft tyre, running the whole race on that.
"What emerged on Sunday, though, was the warm-up issues, which was why we saw more people jumping back to the UltraSoft. If they can manage it and can look after it, the tyre should be OK, but at least it will have better warm-up."
