Yes great article. Sums up how I feel about him. What really rankled was him putting himself in the 'greats' bracket with Fanio and Prost, during his podium speech....I believe he missed out Ayrton. How odd. Perhaps he feels he's already surpassed senna.
Seb you don't put yourself in the 'great' bracket, other people do.
More than likely he purposely did not mention Senna, since he has been linked with Hamilton so often!! 
No I doubt he even considered that. I think he just thought I've got four! I'm better than Senna, I've joined Porst, Schumacher and fangio. Well he can dream on . He's not in Senna league!
I don't think he considers himself higher than Senna, he was merely stating the people has has joined in having 4 championships. Senna didn't so he didn't mention him. It would be weird if he said "I'm in the club with Fangio, Prost, Schumacher and Senna now" you'd end up with people complaining that he isn't in the same league of Senna or Senna didn't get 4 WDCs....
I feel a bit sorry for Vettel sometimes, he does everything right, the politics the racing and the taking control of a team; all the things you need to do in F1 (The kind of things Fangio, Prost and Schumacher did) however he just get's mowed down by fans for "having the best car" ala Prost, Schi and Fangio.
