The 2014 FIFA World Cup is almost upon us and fans around the globe will be scouring the finalised 23-player rosters, eagerly looking for the star names and the players expected to cause the most impact at the finals.

It's not always the biggest names, though, who make the most telling impact at the World Cup.

In fact, it is often the lesser-known talents who take their chance to shine at these major international tournaments—players who come in with somewhat lower expectations compared to their team-mates but leave with a massively inflated reputation. And transfer fee, in some cases.

Here we look at the under-the-radar talent for each of the 32 competing nations, making it relative in each case: The Brazilian or Spanish squads might all be well-known, but some will have a bigger impact than might be expected when considering their experience and relative worth to the squad.
