Nico Rosberg: “We had a mixed day today with some laps lost this morning. However we were able to work through a good programme this afternoon and, of course, it’s always nice to be quickest at the end of the day. In general, I feel happy and comfortable in the car and it feels better than the last time we were here at this track. There is still some work to be done on tyre degradation and our programme this afternoon was helpful in understanding that.” Content on GrandPrix247.com by: staff & contributors, Reuters syndication, GMM service, Getty Images, Formula 1 teams, sponsors & organisations.
