44 Lewis Hamilton
Mercedes F1 W08
When Hamilton has been on form, he's been outstanding. Six poles from the first 11 races attest to his general brilliance on a Saturday afternoon - especially considering the W08 hasn't been the easiest car to set up. Races such as Silverstone also remind us that Hamilton is capable of being in a different league to the rest when Mercedes gets everything right.
But occasionally this year it hasn't, and in these circumstances - Russia and Monaco in particular - Hamilton hasn't looked comfortable. Titles are won on the bad days as much as the good, and Hamilton needs to be better on his bad days.
