The football Association has launched its own investigation into the video, which appears to show Premier League referee David Coote using swear words to describe former Liverpool manager Jurgen Klopp.
Coote has already been suspended by refereeing organization Professional Game Match Officials Limited (PGMOL) pending a full investigation.
BBC Sport was also told that the 42-year-old was withdrawn from an international commitment this week.
However, the nature of Coote's alleged comments also caught the attention of the FA.
One of the comments points out that Klopp's German nationality and the FA rules include nationality of a state among the references that can lead to a serious breach of the FA's rules.
“We are aware of the matter and are investigating it,” the FA said in a statement.
The video, which allegedly shows Coote making derogatory comments about Klopp, was shared on social media.
It has not been verified by the BBC and it is unclear when it was filmed.
A source told the BBC that PGMOL's investigation considered the video to be genuine.
Coote is one of the Premier League's most experienced officials and has been officiating games in the top flight since 2018.
The video shared appears to refer to a Premier League game that Coote refereed Liverpool and Burnley in July 2020, the score ended 1-1.
Klopp criticized Coote after the game, saying the referee had failed to award foul after foul on Liverpool's players.
In the video, the man said to be Coote says that Klopp “had a real hit on me when I beat them against Burnley in lockdown”. He describes Klopp as arrogant and insults him several times.
The video shows him with another man and lasts just over a minute. The circumstances under which the video was created are unclear.
PGMOL says it will have no further comment on the case until the investigation is complete.
