Massa vows to play fair in Brazil

Schumacher trails Fernando Alonso by ten points with just the Brazilian Grand Prix remaining, meaning the German needs to win the race and Alonso to fail to score in order to take the title.

The championship situation has led to speculation about Ferrari's tactics, but Massa says there will be no dirty tricks to help Schumacher.

"I am going to be honest. It is important to fight and compete, and I want to win the best possible position. But I am not going to be dirty," Massa told reporters in Brazil.

"There will be no dirty tricks. We will do things only in an honest way.

"I am going to help Michael, because the championship situation is very complicated but I will only help him in an honest way."

Massa admits he would love to win his home race, but his chances will depend on what Alonso is doing in the race.

"There is a chance to fight for victory and if Alonso is in the top eight," said Massa. "Then even if Michael wins then it doesn't change anything in the championship so that would give me a chance. But we have to work together for the championships.

"Maybe Fernando doesn't finish in the top eight, no one is thinking about that, and of course I will help Michael to win."
