Well, the European teams have a different style of play (for the most part). Most of their players play for well known club teams (Real Madrid, Barcelona, Arsenal, Chelsea, and dare i say Juventus?) and the type of play tends to be very strong defensively. Look at Arsenal in the Champions league...broke the record for longest run of giving up no goals. And that was with a bunch of 18 - 20 year olds playing defence. Those same players also play in the World Cup. Now, i am an Arsenal fan if you hadnt picked up, so sorry for a biased opinion on some players.
Europeans play a mechanical, methodical game. They (like England for Example) rely on set pieces, or a string of passes to pick apart a defense. In the Premiership League, where many of this World Cup players play, the top three teams are known for their passing capabilites (Arsenal more so then the rest) which can result in fluid play that looks like artwork. It can cause defenders to get pulled out of position, or beaten with a quick one-two, or frees up room to make a through pass.
The Americas (lets just ignore the US, since they really do suck) have an entirely different style of play. Brazil, for instance, rely on pace and fancy moves and skills. You'll notice that those sort of countries (argentina too, mexico somewhat) are more offensively minded and have very little in the way of a big-name defenders.
The Africans are much the same way, going for finesse and speed. Unfortuneately for them, it usually doesnt work against a strong European team.
Think of it this way: Europeans go for a static, strong defense, with probing runs and passes and a method to picking apart a defense. A solid team makes this hard to do, which is where the skill of the individual comes in. The Americas rely on fast pace and skill to beat a defense, but what they have on offensive they usually lack in defense. Possesion is their best way to shut down an opponenet. The Africans are quick and rely on pure speed to beat defenders. This works often, though they dont always get a result. They tire out faster, which usually results in their game falling apart.
