China Sunday quotes: Red Bull

Mark Webber - 14th: "It was going reasonably well until I got up to Nakajima, but it's so difficult to follow cars through the quick sections here. I tried my best, the strategy was always going to be difficult with a ten place penalty, but the guys from Red Bull did a good job. It's a shame for Renault, as that was the first engine failure for us."

Christian Horner: "Unfortunately yesterday's grid penalty was always going to be a massive handicap in the race today. Mark drove a good first stint, passing several cars, he made progress in the second stint until he got stuck behind Nakajima, which killed his chance of progress.

"With one further stop before the end of the race, 14th was as much as he could achieve today. David drove a good race on a one-stop strategy, but unfortunately we just weren't quick enough. He got close to Vettel at his last stop, but tenth was all that was possible."

Fabrice Lom, Renault, Principal Engineer, Track Support: "A very tough day. Mark had a great race, but with the penalty he received, he was too far back for it to make any impression. He had a very good first stint and overtook several cars, but we had to make a pit-stop quite early. He then got stuck behind Nakajima and it wasn't possible to overtake. For David, it was a difficult race on a one stop strategy - but he drove well. The same engines will do Brazil, so they have still a long way to go."
