China Sunday quotes: Sauber

Sergio Pérez - 11th: "I must say I am very disappointed. I had a very good start, and for the entire first stint it really looked to be going very well for me. But then when I picked up the medium compound tyres I lost a lot of performance from lap 17 onwards. Actually I feel I would have been better off with a three stop strategy, but you never know. The pit stops as such were good, but at both I lost time at the launch because we had a problem with the clutch. However, this is racing and we will do better next time."

Monisha Kaltenborn - CEO: "We are obviously disappointed with this result. After our strong qualifying we expected more. However, we were not fast enough, and our strategy didn't work out - both our drivers got stuck in traffic. For the fans it was a very exciting race with a lot of overtaking right up to the end, which shows how fierce the competition is. Congratulations to Nico Rosberg and Mercedes for a well deserved victory."

Giampaolo Dall'Ara, Head of Track Engineering: "This was definitely not the race we were expecting, hence we are disappointed. A number of factors didn't go the way we wanted. First of all Kamui had a poor start, then his tyres wore out earlier than expected, and he had to pit earlier than planned. He then got stuck in traffic. Initially we had a three stop strategy for both cars, but then we didn't want Sergio to have the same problem and we reverted him to two stops, which was still a good strategy. But then we lost time at the first pit stop with a clutch problem, this cost him two positions and, as the final point, we expected overtaking to be easier for our cars, which eventually didn't happen. All these factors led to a disappointing result."
