Korean GP: Mercedes Sunday quuotes

Nico Rosberg - DNF: Unfortunately this has been the second poor weekend in a row for me, and it's very frustrating to be taken out twice in the first corners of the race. Kobayashi hit me from behind today and that was my race over. The one small positive to be taken from the weekend is our qualifying performance which was a small step forward. Now I'll look forward to India and hope for a bit more luck there.

Ross Brawn: It was a difficult race for us today. Nico was hit by Kobayashi on the first lap for the second race in succession, and to lose him again through the error of another driver was extremely disappointing. Michael did all that he could today but we struggled to keep the tyres up to temperature. There were parts of the race where the tyres were working properly and we were more competitive, but too many periods where we struggled. We need to look at how we can improve that situation, and we will keep working hard to make progress at the final four races.

Norbert Haug: Nico was once again the victim of a crash on lap one when a competitor drove into his car. This damaged the radiator which put an end to his race and, as in Japan, it was through no fault of his own. At no stage did Michael's car produce the grip we had anticipated. We need to quickly put this race behind us but not before a thorough analysis, with an understanding of why we got it wrong today.
