I'm gonna say Alonso will win it. Button has a good chance as he is one of the smoothest drivers out there so he will take good car of his tyres.
Agree on the tyres there but he has a bit of work to do. Its just too early to tell I guess with this fuel situation.
Heart says Button, head says Massa.
I did like how at the end of Q1, all the top 10 drivers were together chatting and congratulating each other...all except Schumacher who was out side watching the tyre bloke test pressure / temp on one of the McLarens. He was having a good old nose round the car too
