Boca currently sit in 3rd position in their group and know that only a minimum 3 goal win tonight, will ensure their progress regardless of what happens in the other fixture.
They are currently in second place in Primera A, their domestic league, just two points behind San Lorenzo and failure to reach the next stage of the Copa, would be a massive disappointment.
Bolivar are the group whipping boys and are also struggling in the Bolivian league, where they are 11th of 12, only off the bottom on goal difference. They actually meet the basement club at the weekend, in what will be, for them, a much bigger game.
Bolivian sides have a very poor record in Argentina and have lost on their last 7 outings in this competition, conceding, interestingly enough, an average of 3 goals per game.
