Brazil Saturday quotes: Sauber

Nick Heidfeld - 16th: "I must admit I am a bit annoyed. Dry conditions would have suited our car better, but that's not under our control. What we could have done better was the timing in Q2. My tyre change was two laps too early, which meant I wasn't on the track when the conditions were at their best with a set of tyres in good shape. However, as I said, in dry conditions we can be strong here and the forecast for the race tomorrow says it will be dry."

Peter Sauber, team principal: "It was a typical Interlagos weekend with an unexpected grid. Congratulations to the Williams team and, in particular, to Nico Hulkenberg, who did a fantastic job to grab pole position."

James Key, technical director: "As predicted the rain came today. This morning we went through a programme trying to understand the different conditions and, in particular, the cross over between extra wet and intermediate tyres. We seemed to lose some competitiveness in wet conditions compared to yesterday. The main issue seemed to be warming up the tyres. We made some changes for qualifying, where it was crucial to hit the track and tyre conditions at the right time. Kamui did a reasonable job to get close to Q3, after he had some difficulties in the morning. Nick was a little less happy, and he also suffered from some traffic. It's unfortunate we didn't get through to Q3, but equally it's going to be a dry day tomorrow, so we should be more competitive and we will fight hard. Finally congratulations to Williams and Nico Hulkenberg on the pole position."
