Andy Robertson was left raging after an incident with the linesman in Liverpool’s Premier League clash with Arsenal on Sunday afternoon.
The Reds desperately needed a victory at Anfield to keep their chances of qualifying for next season’s Champions League alive.
But they got off to the worst possible start against the league leaders as they fell behind after just eight minutes.
Gabriel Martinelli was gifted the ball in a dangerous position by Virgil van Dijk and he gobbled up the opportunity with both hands.

There were no further goals for the remainder of the half as Arsenal held a 2-1 lead at the break.
Andy Robertson clashes with linesman in Liverpool vs Arsenal
Things got heated at just after the half-time whistle blew as Robertson clashed with a linesman.
Robertson was seen protesting with Constantine Hatzidakis as the official made his way to the centre circle.
The Scotsman then appeared to be elbowed by Hatzidakis. Watch the moment below…
Robertson was, understandably, not happy at all.
He was given a yellow card by referee Paul Tierney for his protests.
Roy Keane’s reaction to Andy Robertson being elbowed by the linesman
Roy Keane was covering the game as a pundit for Sky Sports.
He did not feel much sympathy at all for Robertson following his clash with the official.
He said: “I’ve not seen anything like it really, But Robertson… does he grab the linesman first? I’m not sure.
“But Robertson’s complaining. He should be more worried about his defending.
“I’ve watched Robertson a number of times and he is a big baby. Just get on with the game and concentrate on your defending. He does grab the linesman first.”
It remains to be seen whether Hatzidakis will be punished for his actions.
