Sebastian Vettel closes in on a third-successive world championship at the Brazilian Grand Prix.
But Ferrari rival Fernando Alonso is going all out for his first driver's title since 2006.
Vettel and Alonso will finally settle who will win this year's F1 driver's title in this weekend's season ending Brazilian Grand Prix.
Red Bull's Vettel is 13 points clear of Ferrari's Alonso following last week's US Grand Prix.
Vettel said he was feeling confident but the unpredictability of the weather in Brazil could cause some problems.
However, Alonso knows that if he wins at Interlagos and Vettel finishes lower than fourth he could win the Driver's Championship. -- ANC Dateline Philippines
