Fernando Alonso-My choice. He's far enough ahead and the Reanult has enough speed and reliability to win even if he doesn't win any more races this season.
Kimi Raikkonen-Very fast, but I'm still not convinced about the Reliability of the McLaren. My pick for 2nd, and he will keep it close.
Michael Schumacher-Bridgestone tires aren't up to the task this year if the track is warm, and are not fast enough out of the box to qualify well. Will win a couple of races in cooler temp races on tracks that suit the Ferrari (Magny Cours, Monza, Canada, Hockenheim, China)
Jarno Trulli-May win a race or two, but won't finish high enough regularly to be able to catch either Raikkonen or Alonzo.
Juan Pablo Montoya-Too far behind, slower than Raikkonen
Rubens Barrichello-Too far behind, slower than Schumacher.
