Sweden were unable to qualify for the tournament in the summer, and despite being named on the 23-man shortlist, Ibrahimovic believes that missing out on competing in Brazil means that he will not be named the world's best player by FIFA.
"I think I have just played the best season of my career," Ibrahimovic told PSG TV. "That's one of my objectives - to be better each year and always improve.
"I've been nominated, but it will be difficult because I didn't play in the World Cup. A lot of fantastic players shone at the World Cup, so they'll have a certain advantage but, as long as I do what I can do, that I achieve results and I play at a high level, I can aim to win this award.
"That's what I try to do anyway day after day, by working again and again."
Ibrahimovic is expected to return from a heel injury against Lorient on the weekend.
