Roy Keane had the Sky Sports studio in stitches after Liverpool 2-2 Arsenal

Roy Keane had the Sky Sports studio in absolute stitches after Liverpool's 2-2 draw with Arsenal at Anfield.

Roberto Firmino came off the bench to head home a late leveller in an enthralling fixture where Arsenal led 2-0 through goals from Gabriel Martinelli and Gabriel Jesus.

Mo Salah pulled one back before missing a penalty, while the pulsating fixture also featured one of the most shocking moments of the season when a linesman appeared to elbow Andy Robertson at half-time.

After Jamie Carragher tweeted about the claim, Sky Sports showed a number of different angles of the incident whereby Constantine Hatzidakis raised his elbow at the Scot after he grabbed him.

Robertson was fuming and after being booked by referee Paul Tierney, continued to rage as he walked down the tunnel to the dressing room.

But Keane did not have any sympathy for the left-back and simply branded him a "big baby" in a half-time rant where he told Robertson to "concentrate on his defending".

The bizarre altercation was a key discussion point after the game but Keane doubled down on his comments and again repeated his "baby" jibe on many an occasion.

"What's he going over to him for and what's he complaining for? I said it at half-time, Robertson what a baby. What a big baby. Get on with the game... Baby."

"Robertson, what a baby! What a big baby...baby!"

The final use of the word tipped the whole studio over the edge, with Roy Keane, Jamie Carragher, Gary Neville and David Jones in utter hysterics and unable to hide their laughter.

Even Keane himself was laughing in an utterly brilliant moment.

Manager Jurgen Klopp made no comment on the matter even though he said he had seen what happened.

Pundits have been calling for the assistant referee to receive a substantial ban for lashing out and PGMOL, the body which governs referees, issued a statement to say they were investigating the incident.
