Belgium Sunday quotes: Toro Rosso

"Given how difficult this track is, I think the weekend went better than expected, as we showed we had a good race pace compared to the Red Bull Racing cars. It was a job well done apart from a problem with the right front wheel during the pit stop which cost me a few seconds, that meant I could not fight with Button. But he retired anyway."

Sebastian Vettel - DNF: "I retired because I could not steer the car to the right. It was a problem with the steering but we don't yet know exactly what it was. In left hand corners it was fine. The problem was getting worse and at first we thought it might be something related to the tyres.

"But as soon as I left the pits with new tyres and went into the first right hand corner, I could feel the same problem. A real shame as the race was only five laps old and we seemed to have quite a good race pace."

Gerhard Berger: "We had a good race with Tonio, apart from a small problem with the right front during the pit stop. The rest of his race was consistent and quick. He was able to fight with the Honda, running at the same pace. I think twelfth is an optimum result for us on a day when few in front of us had any problems.

"It's a shame Sebastian was unable to get past the opening laps because of a steering problem we are currently investigating. We are testing in Jerez next week and we will continue trying to make progress to the end. We cannot afford to lie back."
