Nobody is bootlicking referees (outside of like one City fan I’ve had the pleasure of).
People dislike Arteta’s petulance. And his rant was an example of that. The goal also was not that controversial, and especially compared to the shit other teams have been getting this season.
So to blow up over that just seems like a sore loser. He could have blown up over the Bruno G incident and would have likely been better received (though that would have drawn more attention to Havertz).
You could say the same for chemical doping…
