Liverpool's 2-2 draw with Arsenal at Anfield on Easter Sunday had plenty of drama, but the most contentious part came when assistant referee Constantine Hatzidakis seemingly elbowed Andy Robertson just after the half-time whistle had sounded.
Hatzidakis is currently suspended by the Premier League referees' body, the PGMOL, pending an investigation into the incident, while Robertson received a yellow card for approaching the assistant referee, which, under the laws of the game, is correct.
