I thought the officials favored Spain enough to decide the match. Robben was held and deserved a penalty shot; instead they gave him a yellow card. The red card against Netherlands that decided the game was not warranted. The Spanish did play well, but the officiating was decisive.
I don't know about that. The ref could have and should have red carded de Jong for kicking Alonzo in the chest.
Webb, the English ref, is a very good ref and I'm betting he didn't want to decide the match at that point, which it probably would have.
The red card was because the it was the player's second yellow card; and it was well-deserved. A second yellow card requires the red card also be shown and the player sent off. The ref had no other option.
IF Robben was held, it was minor and Robben was also pushing off. Good no-call.
