It is happening again. Nearly a year after Rio de Janeiro hosted World Youth Day, millions of screaming, face-painted, flag-waving fanatics have flocked to Brazil to fill up the streets and stadiums and make some noise. But this time it’s not the Catholic faith or Pope Francis inciting these pilgrims, but rather their love of a sport and the likes of Ronaldo, Suarez and Messi motivating them as they journey to worship at the altar of soccer, or as they call it all over the rest of the world, football, for the World Cup 2014. Noting the similarities in dress code and nationalistic pride between the two groups of pilgrims (or disciples, zealots, or supporters, depending on which vernacular you prefer to use), we thought we’d have a little fun and make a game out of distinguishing between the two. So it’s up to you, take a look at the slideshow below and guess if the image comes from last year’s World Youth Day or this year’s World Cup.
