Refereeing body PGMOL is investigating a video circulating on social media which appears to show referee David Coote making derogatory comments about Liverpool and the club's former manager Jurgen Klopp.
The video, which has been widely shared on social media, has not been verified by the BBC. It is unclear when it was filmed or its authenticity.
Coote, 42, refereed Liverpool's 2-0 win against Aston Villa on Saturday. He is one of the Premier League’s most-experienced officials and has been refereeing matches in the top flight since 2018.
The video being shared appears to refer to a Premier League match that Coote officiated between Liverpool and Burnley in July 2020, which finished 1-1.
