Though some women have attended selected games in recent years, Open Stadiums has said that too few fans could buy tickets and they faced harassment from morality police.

FIFA president Gianni Infantino later Thursday cited his own role in the campaign which including pushing for some women to be allowed to attend the 2018 Asian Champions League in the same Tehran stadium. That breakthrough came months after Iran fans brought the issue to games at the 2018 World Cup in Russia.

“Thanks to the ongoing dialogue between FIFA and the Islamic Republic of Iran Football Federation, progress is being made,” Infantino wrote in a post on his Instagram account.

The FIFA leader said he had discussed with Iran state president Ebrahim Raisi Raisi in New York three months ago “the development of women’s football in the country and the progress made regarding the presence of women in football stadiums.”
