Arsenal forward Kai Havertz should have been sent off against Brentford earlier this month.
The German scored a late winner in a 2-1 success for the Gunners at home recently.
Now it is revealed by an independent review panel that he should have been given a second yellow card for diving earlier in the contest.
“Havertz is already falling when the defender makes contact, brushing Havertz's hip," the ruling read.
“The panel unanimously agreed the on-field decision was incorrect and Havertz should have been awarded a second caution for a "clear act of simulation"."
The issue is that VAR could not have intervened, as they cannot give out second yellows.
