Refereeing body PGMOL to investigate Andy Robertson’s clash with linesman

Refereeing body PGMOL is set to investigate after Liverpool defender Andy Robertson appeared to be elbowed by linesman Constantine Hatzidakis in the Reds’ match against Arsenal at Anfield.

PGMOL intends to “review” the extraordinary incident which happened after the half-time whistle was blown, with Robertson remonstrating with and possibly coming into contact with the assistant referee.

Sky Sports cameras zooming in on the confrontation showed Hatzidakis then seemingly throwing up his arm and making contact with Robertson, who gesticulated that he had been hit by the official.
