'For a century, one duel has halved Buenos Aires. The God of one half is the Devil of the other"
- Eduardo Galeano
Occasionally in life, the stars align. Shining specks in the night sky meet, forming patterns that are romanticised from the safety of planet Earth. Get a little closer - approximately 4.24 light-years closer - and a star bares its teeth. Face a ball of furiously burning gases, and Twinkle Twinkle Little Star suddenly loses a touch of its charm.
Back down to Earth, in Buenos Aires, Argentina, two more combustible entities are set to collide. The constellation of the Copa Libertadores, South America's top club competition, has guided bitter rivals Boca Juniors and River Plate towards a stellar collision that will dwarf the magnitude of cosmic activity.It's been 58 years since the inauguration of the Copa Libertadores, yet the first that has graced a final between Boca Juniors and River Plate. If fate wasn't clear enough, this year's final is the last that will be played over two-legs at each team's home ground, meaning that both Boca and River will take their turn to welcome their arch nemesis to their own, spitting cauldron.
The derby, the superclásico, is widely considered to be the greatest in world football, and is regularly dubbed the holy grail of the sport's 'bucket list'; attend a superclásico and you've done it all. Take a stroll through Buenos Aires and the presence of the two teams is unavoidable. Whether it be the ragged replica shirts, the branded shop fronts or the murals of Riquelme and Aimar, the city breathes from two lungs, one blue and yellow, the other red and white.
