Well if we're predicting then this is my top 5
Hamilton
Schumacher
Button
Massa
Vettel
Alonso may pop his head in and Button will be a close fought thing with Massa and Vettel. Although I do think Button has every chance to take it back in 2011 once he beds in with the team, car permitting. I am a huge Button fan so hopefully this season will be a fight amongst the McLaren boys.
Going to be a tight one this year.
