Mikel Arteta's patience with referees appears to have run short, with Arsenal having been subject to some contentious officiating this season.
Video Assistant Referee officials forgot to draw lines to see whether Christian Norgaard was offside in the draw with Brentford. The week prior, the north Londoners were denied another penalty following a clumsy-looking tackle by Neal Maupay on Gabriel Magalhaes.
Then, in the goalless draw with Newcastle at the Emirates Stadium last month, Arsenal were denied a penalty after Gabriel's shirt was pulled by Dan Burn. Despite the Gunners' protests, VAR did not award the home side a spot-kick.
