Well in my opinion it was a surprise, cause typically plays better as a team, where South Korea has some individualities, and the results have also been in favor of Netherlands - 13place at World Championship where Korea didn't even qualify, then second place at European Championship... even the bookmakers didn't really give South Korea a chance of winning ( the odds for Korea were about 7.00, and for Netherlands about 1.10 ) let alone 3-0, so for me it is maybe not something unbelievable, but really unexpected
