Bottas got into the thick of things in Barcelona during pre-season testing, with Mercedes non-executive chairman Niki Lauda happy with how the team's new driver has settled in.
But the F1 legend also believes that Mercedes' new recruit isn't a match yet for start driver Lewis Hamilton, an assessment which isn't unsettling Bottas however.
"I can deliver," the 27-year-old driver told Germany's Sport Bild.
"I know I was lucky with Nico retiring. It was always my goal to be in a world-class car some day, and thanks to him this has now become a reality.
"Honestly, I feel no more pressure than before. I simply know that I have been given a special opportunity to drive the best Formula 1 car ever.
"I have much more to win than lose," he concluded.
The prospect of lining up against triple world champion Lewis Hamilton is not a concern for Bottas, even when looking back at Nico Rosberg's challenging relationship with the Mercedes stalwart.
"He is a real benchmark," Bottas added.
"For me, it will be interesting to see how he sets up the car and how his driving style works. I'm watching a triple world champion at work so to not use that opportunity would be stupid.
"For sure I won't give up," Bottas insisted.
"And I won't panic if Lewis is quicker. From the first race I have to be right there, even if I know that my learning curve is steep."
