Its hard to call:
Obviously Michael did a good job, Ferrari are back on from and he pushed Fernando hard.
Speaking of Fernando, he did an excellent job, not just quick, but he put in some real performance where it counted, on the in and out laps, on those laps between his & MS' pitstops...and he did well considering his lack of luck with the pitstops.
Kimi also did a great job, pulling the car through the field and doing a great damage limitaion job by picking up some valuable pionts.
And finally Nico Rosberg did fantastically for his debeut. A few little hiccups but he did very well to make up for that and put in some exceptional lap times.
Drive of the day, for me, goes to Fernando, once again he kept Schu behind him, turning up th heat where it matters, and held his line well and aggressively at the first corner against Michael, when he came out of his final pitstop.
Nico would have got it, if it wasn't for those "hiccups" i mentioned. Rookie or not, if you make mistakes like that you dont get drive of the day, but if its any consilation he gets 2nd place in my books.
If we was to talk about "Performance of the Day" then I'd have to say none of the drivers deserve it....The whole Renault pit crew do!
Silence is golden when you don't know a good answer.
