Gianni Infantino says he is expecting 'positive developments' at Iran's World Cup qualifying match in Tehran next month.
FIFA President Gianni Infantino has reiterated the world football governing body's calls for Iranian women be allowed entry into its stadiums.
In a statement on Thursday, Infantino said he contacted Iran's football federation and Iranian authorities several times recently and was "hopeful" they were "receptive to our repeated calls to address this unacceptable situation".
"Our position is clear and firm. Women have to be allowed into football stadiums in Iran."
Foreign women are allowed to watch some matches in Iran and Infantino has been urging Tehran to lift the 40-year ban imposed on local female fans after the 1979 Islamic revolution.
Despite years-long efforts, including an ultimatum that Iran would be banned from FIFA events which expired on August 31, the world football governing body has failed to compel Iran to allow women in.
FIFA's statutes prohibit discrimination by member federations, and could allow for Iran to be suspended from international football.
Al Jazeera contacted FIFA to inquire about sanctions that Iran might face if it does not comply but no further details were given.
