Canada Sunday quotes: Renault

Nelson Piquet - DNF: "It's a disappointing end to my weekend, but I still take some positives from the race as the car was good today and our strategy looked really promising. The race was pretty hectic in the early laps, but unfortunately we had a brake problem and so I had to retire the car. It's a shame as we could have challenged for the points today. Now we need to focus on the next race in France."

Flavio Briatore, Managing Director ING Renault F1 Team: "After a good performance in qualifying we had other hopes for the race this afternoon. The arrival of the safety car at the start of the race meant that we had to review our strategy and that penalised us, especially with Fernando. He was then stuck behind the BMW before he retired."

Pat Symonds, Executive Director of Engineering: "Nelson retired due to a problem with the brakes, which caused abnormal wear, but we don't know why yet and we are still investigating exactly what happened. With Fernando we adopted the same strategy as Kubica at the pit stop, but unfortunately we got trapped by Heidfeld, which made our race difficult and ultimately we didn't finish."
