The defender has won the ball, the ball is heading away from the goal, the attacker is not in control, VAR thinks that the angle that shows the foot in front of the knee does not confirm there was any contact, the defender's follow through is retracted so quickly it is not clear if there is excessive, reckless, careless or no contact... in the absence of a conclusive angle from the side showing contact, VAR says no foul...
My point is: I would buy that from the VAR in this case.
That's what I find interesting about this clip. From the most damning angle I don't think its conclusive. From the other angles it looks clean. IMHO
At the same time I could buy RC SFP, YC reckless, DOGSO-R or no foul...
I don't buy definite or easy though here! But YMMV I guess
