The Premier League has had the most World Cup players since at least 2006, meaning World Cup players from every team, Drogba, Kuyt, etc, in fact, let's not forget the Korean who played for Man Utd. as well, I think Park.
That's got to be a good stat.
Still, it seems the "mega-stars" in recent years have been in Spain, Ronaldinho, Messi, now Cristiano Ronaldo who of course, played in England, now they have Gareth Bale. A decade ago, Zidane and Ronaldo. Not to forget Ibrahamovic and Eto'o who were prime big stars there.
