Following their excellent start with a one-two result in both of Friday's free practice sessions, Sebastian Vettel and Mark Webber were feeling reasonably optimistic about the rest of the Brazilian GP weekend. However, they were reluctant to read too much into the first two outings.
For example, Vettel was faster than Webber in the morning and the afternoon but did not regard this as particularly significant: "I think that it was quite good, with the obvious reservation that topping the Friday timesheets is not the most important objective of the weekend. That comes tomorrow and especially on Sunday, Anyway, we'll see."
Webber was talking in terms of a good Friday. He was not unduly worried by the fact that Vettel had been quicker in free practice: "Look, he went out on track later than me and there's not much difference in the times anyway. I think we're very much on a par at the moment."
Fernando Alonso produced the third-best performance on the day, a good three-and-a-half tenths down on the leaders but still ahead of Lewis Hamilton, Felipe Massa, Robert Kubica, Jenson Button and Nick Heidfeld.
