SAO PAULO - All the pressure for Sunday's decisive Brazilian Formula One Grand Prix is on the shoulders of Lewis Hamilton, his one remaining rival for the world title Felipe Massa believes.

The British driver will start the season's closing race with a seven points lead over the Brazilian knowing that he needs just a top five finish to ensure he wins auto racing's biggest prize for the first time.

But he was similarly placed last year only to blow a 12-point lead in the last two races and lose the crown on the final day to Ferrari's Kimi Raikkonen.

Massa accepts he is the big underdog but feels that means he has nothing to lose.

"The pressure on me is zero," the Ferrari driver said.

"It's true that I have a harder job ahead of me to win the world title than for Lewis in terms of points but my game plan for the end of the week is more simple than his.

"The one thing I must do is win. After that it's just a case of seeing exactly what he has done and how many points we can win back.

Massa also said he believed that the home Brazilian support for him could be a telling factor on the race.
