Andy Robertson claimed to have been elbowed by linesman Constantine Hatzidakis at half-time of Liverpool's crunch match against Arsenal. The Liverpool full-back was seen approaching the official, who then appeared to raise his arm towards the defender.

Referee Paul Tierney brandished a yellow card to the Scot for his protestations AFTER blowing up for half-time.

The official was subsequently surrounded by Liverpool players, including a furious Robertson.

And Jamie Carragher, working on the commentary for Sky Sports, quickly claimed that an apoplectic Robertson was "elbowed" by the assistant ref.

He tweeted: "Linesman elbow on Robertson!"

Television replays appeared to show Hatzidakis striking the full-back.

The officials were booed off by the crowd after exchanging stern words with Reds skipper Jordan Henderson, who protested his team-mate's case.

Sky Sports reporter Geoff Shreeves claimed that Robertson was furious as he entered the tunnel, accusing the official of "elbowing him in the throat".
