Everything hinges on the subjective interpretation of condition #4: "Making an obvious action which CLEARLY IMPACTS ON THE ABILITY OF AN OPPONENT TO PLAY THE BALL"
Webb: "Only Donnarumma truly knows if he was impacted by this and we have to look at the factual evidence."
I'm screaming at Owen to ask, "if only he knows, what evidence do you see that he is clearly impacted?"
If none, the condition isn't met and thus the on-field decision is wrong.
