I bet you’re the kind of guy who thinks that the barista hates you specifically because they misspelled your name on your coffee cup.

Humans make mistakes. Refereeing is a hard job and it is literally not possible to get every call right

You seem to believe that there is a magical country full of incredible referees who never make any mistakes. If you could point us in the direction of this fantastic place, it would be great appreciated

I’m not privy to the comms between the referees, but I think most likely what happened was that Grealish was offside so when the ball was played to him, the AR said “waiting” (basically “he’s off but I’m not going to raise the flag yet”). Obviously there’s not going to be an advantage here, so the referee blew it back for the initial foul.

If this is what happened, it was actually really good refereeing, just poorly communicated to the spectators (though obviously it’s possible it was just a cock-up)
