The Paris Saint-Germain striker believes that progress is in the team's hands after a 2-1 victory over the Republic of Ireland moved them into second place in Group C.
The Swedes have three fixtures remaining, with Kazakhstan, Austria and Germany their next three opponents in the qualifying phase.
"I feel we have it in our own hands," Sky Sports News quotes Ibrahimovic as saying.
"If we succeed in winning these two matches [against Kazakhstan and Austria], we will see if the last match against Germany is important."
Sweden take on Kazakhstan on Tuesday.
