Fernando Alonso was "undoubtedly" the best driver of the 2012 season, according to fellow Spaniard and Ferrari test driver Marc Gene.
"The ease with which Vettel has won his titles is abnormal," the former Minardi driver is quoted by EFE news agency.
"For me the best driver this year was undoubtedly Fernando, getting thirteen out of twenty podiums."
In contrast, Red Bull’s German Vettel - who beat his Spanish adversary to the championship by 3 points - was on the podium after 10 of this year’s 20 races.
