Britain Sunday quotes: Toro Rosso

"I had problems from about lap 15 onwards as something got stuck between my back and my seat, so it was really uncomfortable to drive, especially as this is a high speed circuit so it was very painful. That meant I was unable to push as hard as I wanted because of the pain. I also had a lot of understeer right from the start."

Scott Speed - DNF: "I got a good start and after that it was unfortunate that I did not get ahead of Trulli in the pit stops as that would have made our race for us. Then it all came to a quick end as we were letting the leaders by. It was certainly a bit of a complicated incident, because I knew that for about half a lap the leaders were quite close behind us, but Alex wasn't letting them by.

"When I did, I knew that me Alex and Trulli were so close I decided to let Fernando by at the same point as it would have been foolish to hold the race leader up for so long. As we went into the next corner, really tight together, Alex decided to take a very optimistic move down the inside but he couldn't hold it and ran wide into me.

"I didn't see Alex until we were in the corner. I went narrow to try and protect my position because I didn't want to brake late and run into the back of Fernando. "

Franz Tost: "We had a reasonable opening lap, with Scott coming up to twelfth and Tonio in fifteenth. Then they were both overtaking by Rosberg and Massa and after his pit stop, Scott collided with Wurz which put him out of the race.

"Tonio did not finish because of a gearbox problem. Next week we have a three day test in Spa, where we will have some updates which we hope can help us run at a more competitive pace."
