Lewis Hamilton may not be about to sit back and gift Massa the win at his home race in Brazil, but if he did, the British ace could still become world champion.
Here are the permutations that would see the McLaren ace crowned the youngest ever world champion, and the first British driver to claim the top honours since Damon Hill in 1996.
Lewis will be world champion if:
He finishes second
He finishes third
He finishes fourth
He finishes fifth
He finishes sixth and Felipe is second or lower
He finishes seventh and Felipe is second or lower
He finishes eighth and Felipe is third or lower
He fails to score and Felipe is third or lower
Felipe will be world champion if:
He wins and Lewis finishes sixth or lower
He finishes second and Lewis is eighth or lower
If the pair are tied on points on Sunday afternoon, Felipe would win the title by virtue of more victories (six to Lewis s five) or second-place finishes (three to Lewis s two).
