Arsenal say the referees' governing body needs to "address the standard of officiating" following their controversial 1-nil defeat to Newcastle yesterday.
Boss Mikel Arteta described the decision to allow Anthony Gordon's goal - which was checked by V-A-R - was "embarrassing" and a "disgrace".
The Londoners say they hope to work with the PGMOL to achieve the "world-class" standards the Premier League demands.
