Its not cheating to dive when you are fouled, its common sense
We've been here before . Of course it's cheating. It sucks that refs almost never have the balls to blow unless someone falls over, and that it certainly seems that you sometimes have to dive to get the right decision made, but it's still cheating.
This here is the problem, referees don't see it as a foul if you don't fall. Not sure how much there was contact on Robben though regarding this incident.
