The Dutch style of football encourages teams to attack and defend together, the empahsis is on offense and goals.
Those players were so hyped up but couldn't handle solid English defenses and teams that could deal with crosses and set pieces. Another problem with the Dutch league is the bad goalkeeping, we all saw what the so-called next big thing Gomes is like
However, to be honest the Dutch league has produced some of the best attacking players in the recent era, legends like Ronaldo, Romario, Larson, Gullit, Rijkard, Van Basten etc there are so many names the list could go on and on, all these players made their name there.
Holland is like a football factory, they have some of the best youth academies and satellite clubs around the world, they produce and sell, so many of the players in the top teams in Europe started of in Holland.
