US GP qualifying quotes: Mercedes

Nico Rosberg - 14th: I had real problems getting my tyres into the right working window today and it's so disappointing to have not gone through to Q3. It was all about finding the right compromise in the conditions which saw very hard tyres on a very soft track surface, and we saw a lot of surprises today as a result. Tomorrow should be warmer which will improve the situation for us but starting so far back is not ideal. We've worked a lot on our race pace so the car should be strong tomorrow and I'll be pushing really hard to move forward, overtake some guys and score good points.

Ross Brawn: That was a very tough qualifying session and certainly not what we were hoping for. Our car appeared to suffer more than most in the prevailing conditions: the blustery wind was upsetting the car and it was also tricky to bring the front and rear tyre temperatures into the right window in harmony. However, conditions are predicted to be very different tomorrow, and I am optimistic that, with the set-up we have on the cars, we can achieve a decent race result.

Toto Wolff: A very disappointing afternoon for the team. The main challenge was to get all four tyres into the operating window with the front and rear sets working well at the same time. We clearly didn't do that as well as our competitors, which is reflected in the grid positions. But tomorrow is another day where the warmer conditions should bring the track towards us so we are optimistic that the race could play to some of our strengths.
