Lee Mason's VAR blunder during Arsenal's 1-1 draw with Brentford on Saturday has infuriated Mikel Arteta and the Gunners faithful.
The north Londoners broke the deadlock in their tense Premier League clash with the Bees as January signing Leandro Trossard poked home Bukayo Saka's low-cross in the 66th minute. Brentford frontman Ivan Toney netted the equaliser just eight minutes later, although it has since been revealed that Mason forgot to draw the relevant offside lines in the build-up to the goal.
Midfielder Christian Norgaard, who assisted Toney, was in fact offside - a blunder that resulted in the Professional Game Match Officials Limited (PGMOL) contacting Arsenal and explaining the significant error. And it turns out this isn't the first time that the north Londoners have been left aggrieved by Mason.
