AS: "In the early part of the race the issue was we didn't really know how hard we can push the tyres, how fast that Red Bull was going to be, and we didn't know if we were going to run out of tyres at the end of the stint.
"So, Lewis set off, he was working the tyres into a nice region, only able to pull a tenth or so per lap but just building a little bit of a buffer.
"You are trying to get enough of a gap that you are outside that undercut threat. As it happened, we were able to get the tyres to last quite well, Lewis started to push a little bit harder.
"But, the key thing was we wanted to stay on track longer than they did. Because, if we box, leave them out, we then risk losing the win because there is always the VSC and Safety Car threat that would allow them to end up ahead of us.
"When we got onto that Soft tyre, the race becomes a bit easier. We are on the same rubber but it is fresher, we know it is going to the end of the race, we've seen from the first stint we can handle their pace.
"That was really just a case of keeping everything in a sensible condition on the car, making sure we don't damage the tyres, cause a flat spot and just getting it home to the finish."
