Korean GP: Sauber Saturday quotes

Sergio Perez - 12th: "It is a shame, as we were so close to getting into Q3 but, of course, I had to back off because of the yellow flags in the last sector. Well, the positive side is that we have saved a set of fresh tyres for the race. In any case it will be an interesting one because I could not do long runs in free practice to the extent I wanted to."

Kamui Kobayashi - 13th: "I would have been easily five tenths faster but I had to back off when the yellow flags came out. I am quite disappointed, especially as we had improved the car for Q2. In Q1 initially I had problems with oversteer, but our set-up changes worked out nicely. However, here we have a track which allows overtaking and the race is always a different story."

Monisha Kaltenborn - Team Principal: "We showed a strong performance today, which was not rewarded because both our drivers had to slow down due to the yellow flags in the last corner. They both delivered a strong qualifying and, based on the long runs we did yesterday, I'm confident we can have a strong race tomorrow."

Giampaolo Dall'Ara - Head of Track Engineering: "There's no doubt we were unfortunate today with the yellow flags, but we have to take the positive from the day. After having some troubles yesterday, we managed to improve the set-up significantly overnight and both our drivers were very strong. However, I believe the performance of the car is stronger than the results suggest, so we have every reason to be positive for the race."
