In that clip doesn't look clear to me,in fact it looks the opposite that there was no contact until lamella claters into him....but it's only this clip all others show clear contact.It's clear that he is kicked in the back of the knee. Him getting between VVD and the ball does not make it less of a foul.
Not going to disagree with anyone's other view on this as I think it was a certain penalty and not going to argue over a crap quality video that I thought showed the opposite.
