(CNN) American women's soccer co-captain Megan Rapinoe is not happy with FIFA.

The US star forward slammed the soccer federation during a news conference on Saturday, saying it did not respect female players as much as men and calling FIFA out for offering women less prize money than men.

The prize for the 2018 men's World Cup was $400 million. This year's winnings for the women will total $30 million, though FIFA President Gianni Infantino told reporters Friday the organization will double the prize to $60 million for the next women's World Cup in 2023.

"It certainly is not fair," she said. "We should double it now and use that number to double it or quadruple it for the next time."
