Undoubtedly Vettel is a great driver. Yet I am unable to think he is better than Michael Schumacher ever was but then Schu also had stratospheric cars in many of his campaigns.
If we were to add up their combined world titles (3 + 7) when did they actually have cars that were only “just there or thereabouts”?
Compare Vettel’s & Schu’s achievements to Senna or even Alonso who has narrowly missed the championship in all but one of the years he’s been at Ferrari in spite vastly inferior machinery.
