Former referees Mark Clattenburg and Mark Halsey have questioned the reactions of assistant referee Constantine Hatzidakis after the official appeared to throw an elbow at Andy Robertson during Liverpool's 2-2 draw with Arsenal, and both say he could now face a ban.
Shortly before half-time during what proved a dramatic clash at Anfield, the left back approached the official and appeared to shove him, with Hatzidakis responding by raising an elbow which caught Robertson in the face. The incident incensed the Scot, who was then yellow carded for dissent as he and teammate protested to referee Paul Tierney.
The PGMOL have since confirmed they will be investigating the flashpoint, stating they were "aware of an incident involving assistant referee Constantine Hatzidakis and Liverpool defender Andrew Robertson at half-time during the Liverpool v Arsenal fixture at Anfield", adding it would "review the matter in full."
