Speaking to reporters after the match, Arteta called the goal's allowance "an absolute disgrace" and stated his disbelief that the goal was given by the VAR.
The incident followed a similar VAR controversy in October in a Liverpool-Tottenham match. After that game, the governing body for England's referees said new guidelines would be developed to improve communication between referees and the VAR team.
Arsenal also said they acknowledged the huge effort and performance from the players and traveling supporters at St James' Park.
Arsenal placed third with 24 points, while Newcastle is in the number six spot with 20 points in the league standings.
