Pressure - Cover - A 5 year old knows

I was watching the match between Spain and Belgium a few days ago with my 5 year old son. (Background: I really started to emphasize Pressure-Cover to his team this season. We'll get to "Balance" soon enough.) Well Spain made one of their typical beautiful goals with short, quick, accurate passes that make it look so easy. As the players celebrated, my son asked, "Why don't they know pressure/cover?" I smiled in my all knowing mind and said, "These are professionals. They know pressure/cover. Look, I'll rewind and show you." Rewind and there it is. Both backs for the Belgium team moved up to pressure the attacking player from Spain leaving NO COVER. I looked at my son with astonishment, "You're right! They don't know pressure/cover."
