It is very clear that pure individual quality wise, this is perhaps the worst world cup ever since football started to be professional. And it explains alot.
2006 was a pretty good tournament, lots of quality, also alot of stars last appearance at a major tournament.
2008 and 2010 to be very honest explained so many things.
Spain had a great team, Germany mostly had its current generation barely out of their teens, Holland had 3 good players, Portugal's smaller "golden generation" that never delivered when needed, and that was about it.
2012 ? Still more of the same. And Italy showing how good tactics could dislocate any of those teams
2014 ? Spain is gone, argentina sucks, brazil worst generation in history, germans forgot how to german, france is decent but far off 1985/1998 generations, africa forgot it could play football, portugal back to mediocrity, Belgium plays the best football, and holland still has those 3 players doing everything.
