Nico Rosberg
We didn?t have a perfect morning and it was tough out there with the low temperatures. They were causing a lot of tyre graining, which made it difficult to do much useful testing. It was a few degrees warmer after the break and that gave a completely different picture. In general, I?m pleased with what we?ve achieved this week ? I did a lot of mileage and the team has done a good job over the winter. I feel more comfortable in the car and the balance is quite good, but we still need to work in a number of areas. That?s why I?m looking forward to testing next week and to see what progress we can make.
