The referee of World Cup continue to make mistake, even if in semi-final

The referees will always do mistakes, but I think at this World Cup some of them influenced the final result. I can't understand why FIFA brings all the unknown referees instead of the well-known ones.

Yes, Van Persie did look off side for the second dutch goal, but the ball came off the defender, so I guess the offside rule might not have counted, but still it was a contentious decision. Also, at the end the referee was making a mockery of the added on time. First it looked like he had called off the match and then he waves a yellow card and then plays on for another minute or so!!

but this time it was not the referee fault, if you watch the replay you'll see that if the player is on offside( i think he were on line with the defender) imagine the assistant, that he doesn't have cameras, and 437463242362 replays for all the different posible angles. 1 thing is that the referee see how a player scores with the hand and doesn't says nothing ( luis fabiano, brasil vs costa marfil) or doesn't indicate a clamorous penalty ( spain vs paraguay, the keeper makes a penalty that also was a red card for the keeper) and another is that he doesn't indicate a very very very adjustated offside

I will remember this tournament not for the so good football (which I saw in two or three matches) but for the tons of wrong referee calls. I don't know if those were just mistakes or something else but those decisions ruined the tournament for a lot of teams.

I think that the off side you are refering to was a very close call. The tv coverage showed the incident from a number of angles and the comentators were still undecided so i would not blame the officials.
