Canadian GP: Sauber race quotes

Esteban Gutiérrez - DNF: "For the entire race the car was difficult to drive, and I was always pushing to the limit. Right from the start everyone was closing in. The first set of tyres was difficult to drive on and a one stop would have been impossible. When I came out from my second pit stop into the fist corner, I went over one of the bumps, the front locked up and I couldn't stop."

Monisha Kaltenborn team principal: "This is a weekend to forget. We knew this track wouldn't really suit our car. If you have weaknesses on the car in addition to a track that doesn't suit you, then it's twice as hard. We have a lot of work to do."

Tom McCullough - head of track engineering: "The circuit's characteristics were going to make it a hard day for our car. Ultimately it was a double DNF, which is very disappointing. On the strategy side we attempted a one stop with Esteban and a two stop with Nico, which was the base strategy today. But ultimately the tyre degradation and wear were too high for Esteban, so we had to convert to a two stopper late in the race and unfortunately he had the incident exiting the pits. Looking forward to Silverstone, that's a track that should suit us better. We have to make sure to get the maximum out of our car."
