Eternal rivals Boca Juniors and River Plate will make history on Saturday as they go head to head in the Copa Libertadores final first leg.
La Bombonera is the stage for the opening joust between the Superclasico foes as they compete for the right to be crowned champions of South America.
Meetings between the sides are typically tempestuous and they will both be desperate to lay down a marker ahead of the second leg, which takes place at El Monumental two weeks later on November 24.
