Monaco Sunday quotes: Red Bull

"Monaco's always a tough race. Once you get into it, you think you've done about fifty laps, but then you see that you've only done about twelve. It's such a hard, physical race and takes a lot out of you."

Christian Klien - DNF: "I lost drive during the race and that was the end of it. It's such a shame as the car was feeling strong until that point and I was up for a good points finish. It's frustrating that the car wasn't reliable and we need to work harder to ensure we get more race finishes. It was a great result for David though, and it shows the car has potential, which is encouraging."

Christian Horner: "It's a fantastic result for the whole team. David's driven well all weekend and was desperately unlucky in qualifying, but now he's got the result he deserved. It was a great strategy from the team, when we decided to change from a two-stop to a one-stop race and David did really well.

"But, let's not forget Christian in all this. He was looking really strong here and was very unfortunate to suffer a loss of drive in his car. We're sure that, without that problem, he would have been right up there too today."
