The Professional Game Match Officials, or PGMOL as they are more commonly known, want everyone to know that they won't tolerate refereeing mistakes.
That is why John Brooks has been replaced as the VAR official for Manchester City's trip to Arsenal, replaced by David Coote. Brooks made a big error while on VAR duty during Brighton's game with Crystal Palace, and that mistake has not been tolerated.
Removing one man for one decision makes headlines, but anyone who has watched half a dozen games this season will know that the poor standard of refereeing is not limited to one man; Coote's name may be familiar because he was the referee who recently missed a glut of potential red cards during Liverpool's FA Cup defeat to Brighton including a crunching foul from Fabinho that even he expected to walk for.
