Newcastle players fiercely protested a perceived injustice - even after Atsu equalises. And let's not forget the injustice of the free kick that Ritchie "gave away" and gifted Liverpool the winner.
Even as Atsu ran to the corner in order to celebrate his equaliser, some Newcastle players were still fiercely protesting a perceived injustice.
Referee Andre Marriner gave Newcastle the advantage when Alexander-Arnold handled the ball on the line to block Rondon's shot, before Atsu followed up to score.
But whether United would have preferred a red card and a penalty, as well as the ability to play against 10 men for 70 minutes, as opposed to a goal, was a debate which raged on.
Alexander-Arnold could still have been booked, if not dismissed, according to the laws of the game even once the goal was awarded - but he avoided any sanction at all.
