Massa sure Raikkonen would help him

"If it is necessary, yes. I did it last year and, for sure, because of my job my teammate was champion," Massa told reporters at Spa.

"If it is necessary, then for sure (he should help).

"He is a very fair guy, as I am as well. That is part of our job."

Massa, winner of four races to Raikkonen's two, is currently in second place in the standings, six points behind Lewis Hamilton and seven ahead of Raikkonen.

The world champion has not won a race since the Spanish Grand Prix in April and Ferrari have admitted the Finn will have to play a supporting role if needed.

Massa said he did not know if there was a deadline to decide when the team switch their efforts.

"I don't know. I didn't talk to anybody about that," he added. "I always had a great support inside the team from the first race, and until now it hasn't changed anything.

"We always need to do the maximum we can to win the race, or even to finish in the best condition for the championship. That doesn't change my mentality."

Massa, however, reckons Raikkonen is as motivated as ever to win.

"I don't think Kimi is not motivated or not passionate about winning. I think every driver is. I think you don't keep racing in F1, especially if you are a successful driver, just to race. You race because you want to win. It is part of the mentality from the good drivers.

"I have known Kimi for two years, and for me Kimi now is the same guy I met at the first race. It doesn't change anything. The result is more important. I am motivated and I am passionate to win, and that is my feeling."
