Britain Sunday quotes: Toro Rosso

Sebastien Buemi - 18th: "It was a very tough race and we struggled to be on the pace and now we must try and work out why, as we have been quicker than this earlier in the weekend. On worn tyres especially, the car was very difficult to drive. Nurburgring will be another difficult weekend, but we are due to get some updates for Hungary, which will allow us to be more competitive and perform much better."

Sebastien Bourdais - DNF: "Regarding my collision with Kovalainen, he changed line twice. At the exit to Stowe, I was on the normal line and he went to the inside, I moved to the outside, then he moved over so I moved across to the other side and he changed again. He braked early, because he'd only just left the pits on full tanks and cold tyres. I was trying to out-brake him, but he should not have changed line like that. It was frustrating and then at the end I lost water pressure and had to stop in the garage."

Franz Tost: "First of all, well done to Red Bull for a fantastic job, especially the drivers, Vettel showing incredible pace in the early stages, with he and Webber easily controlling the race. For our part, we were off the pace this weekend and apart from some small technical problems, we were not at the level at which we expected to be. One of the reasons is that we suffer from the lack of new specification aero parts. We will have these for Hungary, when I expect and hope that this will bring us back to the front end of the mid-field."
