Q. Having delivered this result as a track that has not been your best in the past, does it lift confidence for Monza now?
CH: We know that Monza for sure has always, certainly in recent years, has been our weakest circuit. We know Ferrari will be strong there, as they historically are. McLaren and Mercedes will be strong there, but this result gives us a lot of confidence and we will be going to Monza trying to beat our previous best result, which is a fourth place there. But it is a different challenge to Spa. However, with the performance we have seen in the first and third sector here, hopefully it is a sign of a good omen for Monza.
Q. Did you think about putting Webber on options for the last stint, or was that an easy call to make for the primes?
CH: With the energy you put into the tires, if you damage them in three laps in qualifying - to do 10 or 12 we thought might be too much. And with the prime, he looked really happy on it. It looked as quick after a few laps as the option, so it was logical to keep him on the prime.
Q. Vettel seemed to do quick times on the option, even with the blisters. Were you surprised about that?
CH: Yes. I think by that stage we had got enough information and enough feedback from Pirelli to have enough confidence that the tire could go a certain distance. Then you are into a standard situation in terms of the degradation of the tire.
Q. How much consideration did you give to actually starting from the pitlane?
CH: A lot. You have to take into consideration safety at the end of the day. We had great support from Pirelli, working with their engineers and with the information they provided to us, we were able to make a decision.
Q. In terms of the championship, Vettel has made another big step. So when do you declare it a done deal?
CH: When it is impossible for anyone else to win it! There are seven races to go, and still a lot of points to go on the board. This is our seventh win this year, our 12th pole position. We have got a 100 percent finishing record, but we do not underestimate our rivals. There will be no complacency. We are heads down, focused on the next race – and not thinking anything is done and dusted at this point of time.
Q. So you don't change your stance in terms of development?
CH: We don't change our approach. Absolutely not.
Q. And Webber is still free to race?
Q. You went into this race with a lot of uncertainties, and Vettel had to manage the tire problems. Where would you rank this in terms of his victories?
CH: I think this is up there among some of his best – like in Monaco, where on the hard tire he went so long on that. I think he produced a very, very mature drive here. It is quite often easy to forget that while he is having a conversation with his engineer, he is running at the front of a grand prix. He was very measured, as Mark was. The communication between the car and the pitlane was excellent, apart from the blockage around the safety car.
Q. Do you think Ferrari could have given you more of a fight if it had made the same decision as you at the safety car?
CH: I don't know. I think we just looked quicker. You saw Mark hunted him down from five and a half seconds behind, and it looked like we had more pace today. I think that was one of our most competitive races in terms of outright performance.
Q. Did the drivers support the decision not to start from the pitlane?
CH: We spoke with the drivers about it and said, 'Look, this is the situation, this is the feedback we have from Pirelli.' We sat down with Pirelli, and said we believe that the risk is minimal. We asked them if they were comfortable and they had to buy into that.
Q. Did you feel comfortable?
CH: I don't think any of us felt truly comfortable, but we had to believe in the information that we had and the feedback we had from the specialists. We had great support in that respect.
