Arsenal boss Mikel Arteta says it his "duty" to defend the club after he criticised the officiating in last Saturday's 1-0 defeat at Newcastle.
He said the decision to allow Anthony Gordon's winner at St James' Park was "embarrassing" and a "disgrace".
Arsenal backed Arteta's comments in a club statement, which was called "dangerous" by pundit Gary Neville.
"It is my duty to stand in front of you and give a clear and honest assessment," Arteta said on Tuesday.
"My duty is to defend my players and my club in best possible way.
