Liverpool supporters were left less than impressed with the workings of the Video Assistant Referee after seeing a penalty given to Sheffield United on Saturday.
The Reds fell behind after 13 minutes at Anfield when Fabinho clattered into Oliver McBurnie on the edge of his own penalty area.
Referee Mike Dean initially blew for a free-kick, but changed his decision upon consultation with VAR and pointed to the spot.
Sander Berge subsequently stood up and converted past the newly returned Alisson to give the Blades the lead, to the anger of the Reds looking on.
