but imo this "intentional" thing goes a little too far sometimes. not saying something about this case directly, but imo, players could very often do a better job in putting their hands/arms directly at their bodies (look at badstuber who blocked that shot in the last seconds of the germany/portugal game).
sometimes i feel like they run around the box with their arms flailing around, effectively increase their "blocking" zone and then claim it wasnt "intentional".
obviously i am half german so i dont give a fuck about that situation, but imo its not as black/white as you say it is. i fully expect 2 or 3 out of 10 referees to give that penalty.
