Brazilian GP: Sebastian Vettel must find pace in the race

World Champion and Championship leader Sebastian Vettel says he hopes to "discover pace in the race in Brazil" as he targets fourth or better to retain his title for a third successive season.

The German qualified fourth fastest but importantly starts the race ahead of championship rival Fernando Alonso who could only manage eighth quickest.

Vettel is 13 points clear of the Spaniard going into the final race of the season at Interlagos.
