Sam Michael, Technical Director, WilliamsF1: "It's obviously a pretty disappointing result to finish outside of the points. Both cars finished which is good, but we will go away from here and make sure we have significantly better performance in Monaco. Mark and Nico had good starts but we lost out on the first lap and from that point on spent most of the race in slower traffic, which is pretty difficult to recover from at Barcelona."

Mark Webber: "Our strategy today was similar to a lot of other people but we weren't quick enough here. Barcelona has been a tough venue for us all winter as well as the build up to this event and the race itself has been no different. Finishing one lap down isn't good, but everyone at Williams will be looking for a much more promising showing in Monte Carlo."

Nico Rosberg: "Formula One is different to GP2 where you could always have a fight where-ever you were in the race and quite often you might earn some points. But in Formula One it is different and sometimes you have races where you don't get any points, like today. The race didn't go too badly in overall terms as I improved from 13th on the grid to 11th at the finish. Unfortunately, there was a mistake in my second stop, so I fell behind Trulli, which cost time in the final stint. I couldn't get by him despite trying. I also had my first experience of being lapped in my career today and it is not a pleasant feeling! However, the positive thing is that both Mark and I finished the race and now I am looking forward to Monaco, where we will have a fresh engine and where we should be strong. I was third there last year in GP2, and this is a good omen for me."

Sean O'Mahony, Principal Engineer - F1 Race Engineering, Cosworth Ltd: "It was a frustrating day for us as both cars were obviously quick when not held up. On the other hand, it was good to see both Series 4 engines get to the end of their second race. We had no real concerns about the engines during the race apart from some high oil temperatures at the start due to the hotter than predicated ambient temperature."
