US Sunday quotes: Red Bull

"I understand that Montoya then created a shunt, so we picked up a lot of places there. There's an incident in Turn one almost every year, so I was mindful of being in a position off the grid and keeping it. From there, it was just a battle with Liuzzi and Rosberg.

"The team's strategist guy Will (Courtenay) did a great job today and again my engineer Mark (Hutcheson) gave me some good advice on the radio, so we were able to get out in front of Nico. I'm happy for the whole team. To get these points, especially at this time of year, will help us against Williams."

Christian Klien - DNF: "My start off the grid was actually okay. I passed both Midland cars and heading into the first corner, I was right on the inside. But then it got very tight. There's basically just one clean driving line and off it, it's really dirty. It got too tight for all the cars and I don't actually know what happened.

"I was next to a Williams and then a lot of cars crashed together and there was no way to get through it with no trouble. It's a shame to finish the race this early, because I think we had a chance to get some points today."

Christian Horner: "After a fair bit of chaos on the first lap, David emerged unscathed and, focusing on a one stop strategy, drove another strong race. In a car that was difficult to handle on heavy fuel, he delivered when he needed to and was able to go longer than all the others before his first pit stop.

"Thanks to some great work from the team today, a great pit stop and a good strategy, we managed to get David out in front of both Rosberg and Liuzzi. From that point on he was able to pull away and finish seventh. Congratulations also to Toro Rosso on gaining their first point."
