Lewis Hamilton is the favourite to win a sixth world title of his career.
The Brit beat Sebastian Vettel to the Championship last year with the help-of team-mate Bottas.
However, the Finn is not happy to play the wingman role this time around and has warned his ally he is gunning for blood.
“When I came back [from the winter break] I decided that I’m going to beat everyone this year,” Bottas said.
But can he beat an in-form Hamilton who is closing in on Michael Schumacher’s record?
“Yes, that is my aim and I feel I can do it,” Bottas added.
“That’s the goal but how to get there, that’s going to be hard work.
“Last season was tough, quite tough, but it’s over it’s done.
“It’s made me tougher. I feel it’s a nice fresh start.”
Mercedes have claimed they will treat both drivers equally at the start of the season to give them a fair shot at the world title.
And Bottas knows the importance of getting off to a good start.
“I’ve learned that the first half of the season is always very important,” added Bottas.
“I started the year pretty well, just sometimes lost some points because of different things. I’m ready to go for it and try to be a better me.”
Bottas also spoke of his activities during the offseason.
“I got to Finland, got properly smashed a few times, did anything I wanted to do basically,” he said.
“Then I got a camera, I started photographing, it’s like a new hobby now so sometimes went for a walk somewhere and took pictures.
“I also travelled with my wife and some friends to South America, just for a proper holiday, didn’t think about Formula One.”
