Jul.19 (GMM) Felipe Massa is confident he just needs to keep up his improved form to "ensure" a new contract for 2013.
In a pre-German Grand Prix statement posted on Ferrari's official website, the Brazilian denied that Mark Webber's decision to stay at Red Bull next year is a weight off his mind.
"The only thing that is important for me is that I keep performing in the same way I did in Silverstone," the 31-year-old is quoted as saying.
He admitted he is keeping "an eye" on the 2013 silly-season.
But "I'm sure that driving the way I am now is the only thing I can do and need to do to ensure my future," Massa insisted.
"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."
Massa has raced for Ferrari since 2006.
