REF’s picks

Boca Juniors hold a distinct historical edge when playing continental ties at La Bombonera, making them a solid pick to edge out Vasco da Gama. While the Brazilian side arrives in strong defensive form, the atmosphere in Buenos Aires usually tilts these tight knockout encounters toward the hosts.

1. 1Boca's home pedigree in continental competitions remains one of the hardest tests in South America.
2. 2Vasco da Gama travel well defensively but often struggle to generate clean-cut chances away from home.
3. 3An overly cautious tactical approach from the visitors could frustrate the hosts and lead to a narrow margin.
