Felipe Massa is focused on doing the best he can for Ferrari despite ongoing rumours about his future at Ferrari.
Massa appeared to have a bright future at Ferrari when he missed out on the 2008 drivers' championship by a single point but a serious accident during qualifying for the 2009 Hungarian Grand Prix resulted him in missing the remainder of the season.
Since his return he has struggled to regain the form that saw him fighting for the title and a poor run in 2011 meant he became the first Ferrari driver in almost two decades to finish the season without a podium result.
With his contract due to expire at the end of the season and the Brazilian has been left in no doubt as to what is required from him with both Ferrari president Luca di Montezemolo and team principal Stefano Domenicali warning him he must improve to have any chance of having his deal extended.
However, a dismal weekend in Australia, which saw Massa qualifying in 16th and failing to finish the race, has resulted in speculation that Ferrari were on the verge of sacking him, but he insists he will not let the rumours distract him from his job.
"I really don't care. I don't drive thinking about what others are thinking or saying about me," he told reporters in Sepang ahead of the Malaysian Grand Prix.
"I'm doing my job, thinking about doing my best in the car, which is not what happened in Australia."
Massa has been given a new chassis for Sepang and he believes that could make the difference as he tries to gets to grip with the F2012.
"The only thing I care about is the car. To have the car I know (from testing), not the one I had in Australia. (Changing chassis) is the right thing to do," he went on.
"I really don't care (about criticism in the media), I have a job. The only thing I am working for is to drive the car and get out of the car 100 per cent convinced that I did the best."
