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.
