Looking ahead to the big showdown at a venue built for world title deciders!

It's 4pm and the bus is in full swing along another Texan highway. Ranches, churches, RV Parks and as many fast food joints as you could ever wish for line the route as out of Austin we head toward Houston and the flight down to Sao Paulo.

The scene is set for a brilliant final chapter. Who will win? I've said Alonso all season so don't expect me to change my mind now. It's not logical, the smart money would be on Sebastian. But sport sometimes isn't about logic, it's about the unexpected, the brilliance, the inspirational, the despair and the delight. All of which Interlagos has proved in the past and this weekend, is on the verge of doing so once again. DC
