Felipe Massa has insisted that he is not worried about his future with Ferrari.
Massa's contract runs out at the end of the current season, and his form has raised questions over whether Ferrari opt to keep the Brazilian.
However, after a poor start to the season, in which he scored just two points from the opening five races, he has performed better recently, finishing fourth in the British Grand Prix ten days ago.
"Of course I keep an eye on what is going on with other drivers, just as anyone likes to know what is going on in whatever work they do. But the only thing that is important for me is I keep performing in the same way I did in Silverstone," said Massa.
"In the two grands prix prior to that, in Montreal and Valencia, I should have been entirely capable of finishing in the top five or on the podium. But for various reasons - a spin in Montreal and a problem with the floor of the car in Valencia - that did not happen. Without that, since Monaco, I would have been fighting for the top five at every race.
"I'm sure driving the way I am now is the only thing I can do and need to do to ensure my future. What happens in the drivers' market does not have a significant effect on my position. If I carry on performing the way I did in Silverstone, then I don't feel too worried about my future."
Ferrari are currently fourth in the team rankings with 97 points.
