Boca Juniors and River Plate are set to lock horns in the second leg of the Copa Libertadores finals at El Monumental on Sunday.
The game had originally been scheduled for Saturday, but a ferocious attack on the Boca bus forced officials to postpone the decider and they have rescheduled.
The tie itself is locked level after the Superclasico rivals played out a tempestuous 2-2 draw at La Bombonera in the first leg, meaning the game was already primed to be a tense affair.
