Esteban Gutierrez has downplayed rumours that Sauber's newest partnership deal could spell the end of his time with the F1 team.
Last month, Sauber announced that they had signed a deal with three Russian companies that is believed to hinge on the team putting 17-year-old Sergey Sirotkin in one of the cars.
And it is thought to be Gutierrez who will make way for the Russian teenager.
The Mexican, though, insists he's not worried about the reports as he "knows" where he stands with Sauber.
"They say a thousand things," the 22-year-old told reporteindigo.com.
"Right now the media is so efficient that on Twitter or Facebook or anywhere you want things spread fast - and maybe things that are not true.
"Many people have speculated and are concerned about my position at Sauber.
"I know well what my future plans are with Sauber. I have good communication with them and so I'm focused on what I have to do."
