They have a storied history in Argentina, but now they will go head to head to decide who is the best team in South America
For the first time in history Superclasico rivals River Plate and Boca Juniors will face off in the final of the Copa Libertadores.
The Argentine giants, who both have a long and distinguished history in the competition, overcame Brazilian opposition in the semi-finals to set up a tantalising decider.
Boca have already been in 10 finals and are chasing their seventh title, while River can add a fourth to their trophy cabinet in what will be their sixth final appearance.
