#3 Passing the Torch
Alonso's first world title in 2005 made him the youngest champion in Formula 1 history, beating Emerson Fittipaldi's record by over a year. His second title, though, sealed his place among the great champions of the sport, because he beat one of the sport's best ever drivers.
Ferrari were a joke by their standards in '05, only winning one Grand Prix, the controversial USGP a.k.a "Tyregate". The Scuderia had a resurgence in '06, with Alonso and Schumacher competing for the title throughout the year.
In the end, Alonso came out on top, the first driver to beat Michael in a season-long title fight since Mika Hakkinen in 1998. To be the best, you've got to beat the best, and Fernando has certainly done that.
