Manchester United legend Roy Keane has branded Andrew Robertson a 'big baby' after the claims about being elbowed by the assistant referee.
Liverpool and Arsenal shared the spoils in a thrilling 2-2 draw at Anfield on Sunday, but Robertson's incident with assistant Constantine Hatzidakis grabbed all the headlines.
Replays showed that the assistant referee appeared to elbow the Liverpool full-back, who tried to approach him after the halftime whistle on Sunday evening.

Keane did not care for Robertson's actions and instead criticised Scotland international for his defending in the first half.
"No, not really. But Robertson, do you know what, does he grab the linesman first? I'm not sure, but he's complaining. He should be more worried about his defending.
"Do you know what it is, that Robertson? I've watched him a number of times. He's a big baby. That's what he is.
"Just get on with the game and concentrate on your defending. He does grab the linesman first."
The PGMOL have already confirmed the incident will be investigated.
"PGMOL is 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," the statement read.
"We will review the matter in full once the game has concluded."
