He annoyed me through-out this year, however I absolutely cannot begrudge him the title. He was, as Anthony Davidson said on the Five Live coverage, the fastest driver this year. That won him the title so fair play.
What he needs to do now is mature as champion through next year. Improve his skills, especially at racing with other cars as opposed to sprinting from the front, and I see no reason not to like him. He certainly seemed to be a genuine guy after clinching the title.
The whole finger waving thing was just an excuse for the majority of this board to hate him because he was winning. It's amazing how fickle some here can be. He was hailed as the next god after winning in the Toro Rosso, yet this year as an arrogant little runt. Amazing some people still believe you can be a top level sportsman and NOT be arrogant.
