China Friday quotes: Mercedes

Nico Rosberg - 5th: "It's important for us at the moment that we try a lot of different evaluations during practice to improve our race pace. So I think it was a decent start to the race weekend today as we learned quite a few interesting things. The conditions were so changeable today that it was difficult to take the right decisions in terms of set-up work, and we struggled a little with the front tyres. That may have been caused by the cold temperatures today, and can change very quickly between now and the race, so I am not too concerned."

Ross Brawn: "We had a useful second session on the dry track this afternoon and were able to carry over some of the work that we wanted to do this morning to ensure that we completed our planned programme. Whilst our low fuel runs look good, our primary focus has been on race pace and working to understand the tyres so that we can use them as well as possible on Sunday."

Norbert Haug: "We are not reading too much into today's lap times but we are quite positive about what we have learned in terms of race simulations and the comparison between the tyre types on both our cars. In the limited time available after the wet first session, our team and drivers did a good job finding a solid basis to work from tomorrow."
