It nothing to do with conspiracies. It has everything to do with the stupidity of using world refs. Hell I bet MLS refs/linesmen are a HELL of alot better than those shitty ones FIFA was using, heck they should have just used various refs and linesmen from the various leagues in Europe. But no they thought they should use refs that really dont have the experiance to call these world class games.
The linesmen robbed both Italy and Spain. You say both had their chances to win. Know what, they shouldnt have had to HAVE those chances. Italy had 5 legit goals disallowed in the world cup 2 vs Croatia, 2 vs Korea, and 1 vs some other country that the name escapes me at the moment, they HAVE EVERY GOD DAMN RIGHT TO WHINE. They were out and out robbed by poor officating. With better officiating, Korea wouldnt have made it out of the round of 16. Anyone that says Korea deserved to be in the semi's is just sad.
I dont care if people say thats just how it is. It shouldnt be how it is, yes calls even themselves out in various games, but Italy was robbed through and through, as was Spain, they just happened to be playing the host country. Its a damn good thing Germany won, or it would have been a farce of a World Cup if Korea made it to the finals.
How many goals did Korea have called back that caused them to be knocked out? None. How many goals did they have called back period? Having legit goals disallowed is far worse than getting other bad calls. Korea had very few bad calls called against them.
