Must say that they took their penaltys without any real balls generally , ronaldo , kaka , kroos all hit low , there is a 50/50 chance that the keepers get's that if he finds the direction , unless you hit really hard or millimetrically put it in the corner and the keeper can't get it , but they took them without much strength and didn't try for extreme precision because they were afraid of making a mistake , that is how i see it .
The only ones who took them with balls were ramos (who hit it badly) xabi and sweini , which get's the most credit for having the greatest burden maybe , since his shot could decide the winner
