When Joelinton turned back towards him against the momentum of his body in the close up slo-mo, I was thinking "Oh yea, you can see he's pissed and is about to pop him with a hand/forearm/elbow in the chops"....and then nothing. De Paul is a clown. You can see what the ref thought he saw (I guess), but the VAR must be on a lunch break or something.
