The linesman pushed Robertson’s chin with his elbow as the Scotland skipper approached.

Referee Paul Tierney then issued a yellow card to Robertson despite his vehement protests.
As Roberto Firmino’s 87th-minute header prevented the leads from winning the championship for the first time since 2004, Liverpool salvaged a 2-2 draw. At halftime, Arsenal led 2-1.
Following a pledge to evaluate the event by the organization that regulates referees, PGMOL, Hatzidakis now faces an investigation into his behavior.
The statement read, “PGMOL is aware of an incident involving Liverpool defender Andrew Robertson and assistant referee Constantine Hatzidakis during half-time during the Liverpool vs. Arsenal game at Anfield.”

“Once the game is over, we will fully analyze the situation.”Roy Keane, a former player for Manchester United who now works as a Sky Sports analyst at Anfield, wasn’t impressed with Robertson’s response to the match.
Robertson snatches the linesman first, right? Robertson may be whining, but I’m not sure,” Keane added.
He ought to be more concerned about his defense. Do you understand who Robertson is? I’ve seen him several times, and all that man is a big baby.
“Just play the game and pay attention to your defending. The linesman is the one he grabs first.

Aleksandar Mitrovic, a striker for Fulham, was given an eight-game suspension this week for hitting referee Chris Kavanagh during the Cottagers’ FA Cup loss to Manchester United last month.
Nevertheless, according to former Manchester United defender Gary Neville, Hatzidakis will be the one in danger this time.
Neville said on Sky Sports, “I’ve never seen an official lift an elbow to a player. “I believe he’ll be in serious danger after this game is over,”
