Valtteri Bottas is targeting the world championship for 2017.

With Finn Bottas switching from Williams, Lewis Hamilton's father warned just days ago that the triple world champion is nothing short of a "career killer".

Yet Bottas told Finnish broadcaster MTV that he intends to beat Hamilton.

"My goal is the championship and I really have the opportunity to get it," he said.

"The immediate objective is to fight against [Hamilton]."

To that end, the 27-year-old recently called the man he is replacing, world champion Nico Rosberg, with whom Hamilton shared an acrimonious relationship.

"It was good to talk to him," Bottas said.

"Nico has been in the team for a long time and knows very well how things work from the driver's point of view.

"The most important thing is to know how the team works and how to collaborate with them to get the most out of the car."

The 2017 calendar kicks off with the Australian Grand Prix on March 26.
