This summer's World Cup boasts as deep a field of competitive teams as there has been in recent memory; many of the world's conventional powers will be fielding exceptionally strong teams in the tournament. Previous World Cup winners Brazil, Germany, Argentina, Spain, France, England and Italy are all expected to play a significant role in the knockout rounds, while perpetual late-round teams such as Portugal and the Netherlands are also expected to impress.
At the same time, individual play in the 2013-14 domestic seasons combined with World Cup qualifying results in various regions have established an interesting group of dark-horse contenders. These dark horses extend beyond a country like Belgium -- which recently has cultivated so many individual stars that its lack of relative team success appears to be irrelevant -- to a group of lesser-known individuals and teams that could pose a real threat to an established football nation if they advance past the group stages.

This is not really the case in Croatia's midfield, as Real Madrid midfielder Luka Modric and Sevilla midfielder Ivan Rakitic appear to complement each other in their respective positioning with their club teams....
