I don't totally agree with that as Fisi has been racing in F1 whereas Luca hadn't even driven the car up until Valencia. Also there is the fact that Fisi can be quick on his day and was always a quick driver at certain circuits and when he had preferential or equal treatment (Renault years, depending on team-mate).
There is still not much of an excuse for being as slow as he was..
I know the media have a ridiculous effect on Politics, Sport and all the rest.
But when you qualify for your races last and finish the races last, in a car that got a 3rd and a win in the two races in the hands of your team-mate, the media could call you God and you wouldn't keep the drive.
Sorry, Luca, don't moan when you haven't brought home the bacon!
