Brazil is the world's fifth-largest country by area and the seventh-largest by population.
Football is a huge deal in the South American nation and Brazil exports more players than any other country in the world.
With five World Cup wins, Brazil also leads the way in the game's greatest competition and for many players, the route to international football is blocked by the sheer strength in depth available for selection.
Over the years, many Brazil-born stars have gone on to represent European nations instead. Here, a look at some high-profile examples from the men's game...
Thiago Cionek (Poland)
Born and raised in Curitiba, Brazil to a family of Polish descent, Thiago Cionek applied for citizenship and became a Polish international in 2014.
The centre-back, who also had a four-year spell in Polish football with Jagiellonia Białystok between 2008 and 2012, went on to play Poland at Euro 2016.
