how the hell that was PK for Real??? he didn't even touch him.. even VAR got it wrong...
It was interesting, in the book it clearly reads, you dont need contact, if your action is violent and COULD cause harm , it is a foul , i think this is what the ref saw. As an example, if I walk to you, and attempt to kick you, but make NO contact, as a ref, I can give you yellow card or even red, contact is NOT required.
After all this though, its VERY subjective, IF i was the ref, I think i would make the same call.
