I think it also has to to do with Costa Rica not having a huge following.. Most of other games have been composed of the Brazilians, and the fans of the 2 teams playing (all South Americans teams had a huge crowd).
Huntelaar in. Lance Stephenson out. Dutch want to finish it on the field. They do not want to leave it to chance of PK.
Costa Rica made all of their PKs against Greece so they have good shooters as well. The weaker side settles for PK. The better side wants to settle it during regular time and not leave it to chance. Which is why you saw that Dutch sub for another striker.
I'm aware of that. Dutch sure would like to win it in regular time but if it does goes to penalties, they have 5 reliable PK takers Huntelaar was brought in not only to try and finish the game before PK's but also because he is a good PK taker if it gets there
