Everyone see's the talent they have and predicts them as the next big thing but it never quite works out like that(yet)
Adrian Sutil = Pierluigi Martini
loved by the back of the grid team he joined so much that he stays there for an enternity putting a couple of excellent drives a season that makes people wonder how they'd do in a car higher up the grid.
Paul Di Resta = Jan Magnusen
Lots and lots of hype but no product!- ok its a bit early for this one!
I think that's really harsh on di Resta.... He has incredible speed - but his racecraft in the Force India has been a little lacking! Remember that he was racing in the DTM for 4 years, and so almost has to re-learn how to race single seaters!
One comparison that might seem surprising would be old team-mates Niki Lauda and Alain Prost, due to in one particular aspect: (apart from winning title after coming back from retirement): the latter made no secret he changed his attitude to racing 1985 after learning from the former that it's better to finish second than risk not finishing at all.
Prost was a far more aggressive driver pre-Lauda (as a team-mate) than post-Lauda.
