Canada Saturday quotes: Red Bull

"I'm not sure how they're going to manage with the track tomorrow, but everyone's in the same boat. I think we'll need to use motocross bikes, as it's not realistic in a Formula One car, you'll need to drive on the grass or on the inside of the hairpin."

David Coulthard - 13th: "The track is breaking up, as it did two years ago, and it was incredibly difficult to drive at Turn 7 and at the hairpin. The track was swept between the first and second session, but it was breaking up so quickly that it was like trying to drive on train tracks. When you've got that amount of horsepower on a car that's slipping and sliding, it's incredibly difficult.

"I think we had the pace to run inside the top ten today, but I had traffic on the last runs of both sessions. On the first I was behind Bourdais, and on the second behind Piquet. It's unfortunate to have a continued series of problems, but we're thirteenth tomorrow, and hopefully we can have a strong race from there."

Christian Horner, Team Principal: "After a really promising Q1 and first run in Q2, it's frustrating for Mark to get caught out by the difficult track conditions today. Unfortunately, unlike others that got away with an off-track excursion, he damaged the front of the car sufficiently enough not to take part in Q3.

"After not being happy with balance of his car this morning, David made good progress in the first session, but unfortunately wasn't quite quick enough to make it into Q3 today. We feel with 10th and 13th that we've underperformed."
