Last night (21st), England and Iran played face-to-face.
Before the game, I read a lot about Iranian players refusing to sing the national anthem.
The Iranian national anthem rang in the stadium before England and Iran's Group B match, and all 11 Iranian players refused to sing the national anthem and remained silent.
In Iran, anti-government protests continue in the wake of the mysterious death of Mahsa Amini after being taken away by the police for not wearing the hijab in September.
Iran's national anthem reads that it wishes the Islamic Revolution and the Islamic Republic to be eternal.
Esan Hajisafi, the captain of the Iranian national team, said at a press conference the day before the game, "The situation Iran is in is not good and the players know it."
