The historic inter-Korean World Cup qualifier in Pyeongyang on Tuesday was a blind game of sorts for South Korea with no live broadcast of the game and no fans in the stadium.
There's also a rising wave of criticism regarding North Korea's unprofessional handling of the match.
Soon after full-time, the Asian Football Confederation explained it could not take issue with Pyeongyang not allowing in away fans as the hosting country has full rights over home game marketing.
However, the AFC's competition operations manual states otherwise.
According to this year's edition, the hosting organization should ensure visas and entry to the AFC Delegation, traveling team's official delegations, media and travelling supporters without any discrimination.
This particular clause shows North Korea clearly violated the AFC's guidelines.
South Korea's Korea Football Association is closely reviewing the manual as it specifically states the entrance of media and travelling supporters should be permitted.
However, it's unclear whether an appeal would have any practical result because it's not one of the AFC's binding rules.
The KFA is also reviewing the team's three-day stay in Pyeongyang to see if there were any violations of match operations or international regulations that need to be raised with the AFC or FIFA.
Meanwhile, some video clips of the match were released on Thursday.
The KFA initially planned to televise the clips but uploaded the highlights on its website instead because the low-quality video was not suitable to air on TV.
