I think I agree with David Coulthard when he says anyone one of the top 10 (apart from Button) could have been driver of the day.
Vettel - didn't have the fastest car in qualifying yet put in 2nd, had the better race pace and just cruised away as usual
Hamilton - We have got the old one back! (I hope) Got pole with a stunning lap, finished ahead of Webber who had a faster car, defending really well and gave us a good battle, beat his team-mate all weekend.
Webber - Think this has to be one of his best performances this season, and I think he could have won it if he got past Hamilton in the second stint as he had the best strategy, in the end he didn't but gave us a good battle!
Alonso - He said he gave up, but he did the exact opposite, put in some stunning laps in the end but seemed to be struggling in the second stint.
Massa - Had the old front wing, out-qualified Alonso, had a great start, ran good first two stints and was pulling away from Alonso, the two pitstops that he had though where quite poor, one of them was 6.1s compared to Alonso's 3.6s, then in the next one came out in traffic. Great race by him, I hope we get the old Felipe back!
Alguersuari - Out-qualified his team-mate ran well, benefitted a lot from the safety car as the rest around him pitted a lap or two early, but he had good pace, and had a great race, but did he tie his shoe lace?
Rosberg - Was running well in the first two stints, until he had that massive lock up, ever since then he was on the defensive and lost the position to Alguersuari probably because of fuel being "critical".
Buemi - Got tagged from the start, had to make his way through the field from 20th, costing him a lot of time, he had great pace and only finished 10s behind his team-mate even though he pitted one lap before the safety car. Finished 9th strong performance by him.
Di Resta - Hm...he was quite quiet, had a bad first stint and was one of the first to pit, finished ahead of his team-mate who I feel was on a better strategy, gets a point.
Three worthy mentions though, two who were running well until an incident, Petrov and Schumacher.
Schumacher - seemed as if he had the legs on Rosberg, and was ahead of Alonso until he got take out by Petrov.
Petrov - out-qualified his team-mate by a big margin, was running really while fighting it out with the Ferrari's and Mercedes, managed to make his tyres somehow last the same time as those around him even though they were 4 laps older than everyone else's, in the end crashed into Schumacher.
Kovalainen - strong performance by him aswell, got ahead of both Sauber's in the race, Kobayashi may have had a problem with his wing for a while, but as far as I am aware Perez didn't. Solid by him.
Don't have a clue who to give it too, it's between Vettel, Hamilton, Alguersuari and Buemi.
