Esteban Gutierrez says he isn't worried by talk that his F1 career could be at risk after just one season.
The Mexican made the move into F1 with Sauber with a big reputation at the start of the year, but has so far failed to trouble the scorers – with a best finish of twelfth in Malaysia.
The 21-year-old has also failed to make it out of Q1 on numerous occasions, leading to reports that he could find himself ousted at the end of the year.
The arrival of new Russian backers at the Swiss outfit, and the fact that Sergey Sirotkin is being primed to race for the team next year, has done little to dampen the speculation, although Gutierrez himself said he wasn't getting concerned.
"All I know is that there is a lot of speculation," he was quoted by Totalrace
. "There are many people (drivers) around, many cars (for 2014), and this generates a lot of rumours and information that is not accurate.
"Right now, the most important thing is that nothing has changed this season. I'm focused on doing a good job. The entire career of a driver depends on results, and this is what I am focused on.
"It doesn't matter much what I did or did not do in the first half of the season. The important thing is what I do in the second, and in this way I think I have much to gain and little to lose.
"I am determined and will make every effort to achieve what I have always wanted in my life."
