Ibrahimovic retired from international football after Euro2016 and missed Sweden's World Cup qualifying campaign.
However, the former Manchester United striker has announced on US television he will be making a comeback.
"I will go to the World Cup, it is the only thing that I can say," said Ibrahimovic.
"If I say more, people will blame me. I have to be careful what I say now. A World Cup without me would not be a World Cup."
