Yes but Senna did not race for a proper team until 1988, Vettel went to Red Bull
in his 2nd full season as an F1 driver...
How many victories did Webber have in the same period? That's about where the Red Bull really was. Vettel was just able to get more out of the car than Webber.
Also, in 2009 he won already, and the car wasn't the best that year. Remember Brawn? And it probably wasn't the best in 2010 either - equal best, at best.
Oh, and winning at Monza in a Toro Rosso in 2008.
Anyway, haters gonna hate.
