The Football Association has launched its own investigation into the video that appears to show Premier League referee David Coote using foul language to describe former Liverpool boss Jurgen Klopp.
Coote has already been suspended by refereeing body Professional Game Match Officials Limited (PGMOL) pending a full investigation.
BBC Sport has also been told the 42-year-old has been withdrawn from an international commitment this week.
However, the nature of Coote’s alleged comments are also attracting the attention of the FA.
Coote used Klopp’s German nationality to preface one of his comments and FA rules state nationality is one of the references that can lead to an aggravated breach of its rules.
“We are aware of the matter, and we are investigating it,” said the FA in a statement.
