The VAR for Liverpool's 3-0 dismantling of Man United on Sunday has been told that they made a 'baffling' mistake.
New Reds manager Arne Slot made it three wins from three as his side crusied to a 3-0 victory at Old Trafford.
Luis Diaz netted twice before Mo Salah sealed the three points with a crisp finish as Erik ten Hag found himself back under huge pressure once again.
And it could have been more if an incident during the second half had been reviewed.
United new boy Noussair Mazraoui appeared to catch Cody Gakpo from behind in the area but referee Anthony Taylor played the advantage which resulted in Darwin Nunez shooting wide.

Replays showed the challenge was made in the area and former Liverpool striker Neil Mellor believes VAR should have stepped in to award the penalty.
VAR John Brooks and assistant Harry Lennard did not review it and Mellor was left baffled
He tweeted two images to justify his thoughts, writing: 'referee sees foul on Gakpo and indicates advantage… Nunez shoots wide,' Mellor wrote.
'Contact was inside the area… so why hasn't VAR told him he was right and contact in area so should be a pen? Baffling decision.'
The decision had little impact on the result with United well beaten by their rivals on the day.
