I don't care how much anyone poo poo's the Netherlands approach, but I think it was the right one. They were determined to play a tough, gritty defensive approach and try to hit on the counter. I serioulsy doubt that part of the plan was Van Merwyck telling De Jong to kick someone in the chest, though, but rather that he wanted the Dutch slowing the Spaniards down with fouls.
Look at the results. Spain was still able to get some quality attacking in throughout the game, but imagine if the Dutch had been pushing forward; IMO, Spain would have scored 3 or 4. Look at how many times Robben had great chances at goal; the counter gave the Dutch every chance to win. Okay, with a little bit of extra time left the Dutch lost a defender to two yellows and Spain scored the winner, but look how close that strategy had them to penalties or outright victory, if Robben manages to score earlier. Now think about how much space Spain would have had to work with if the Dutch had pushed forward constantly.
I think the Dutch clearly knew they weren't as good as Spain playing wide-open soccer, and went with a good strategy to try and win the game. And, if Iniesta had ended up on the left side of the box, that strategy likely gets them to penalties
