Bolivar VS Sao Paulo

Bolivar, the home team, is in excellent form. They've won 4 out of their last 5 games, losing only once. They advanced past Grêmio in the previous round and have achieved four consecutive home - wins. Their forward, Aspillaga, scores goals consistently per game. The whole team has adapted well to the thin air, and their high - pressing style makes it difficult for Brazilian teams to cope. There are no key injuries in the lineup, and their home - ground offensive performance is outstanding. Historically, when playing against Campeonato Brasileiro Série A teams on their high - altitude home ground, they've always posed a threat. In 2013, they defeated São Paulo 4 - 3 at home, which gives them psychological confidence. On the other hand, São Paulo is in a slump. They've only won 1 and lost 3 of their last four Campeonato Brasileiro Série A games. They've failed to win in multiple consecutive away matches. They've lost their defensive mainstay, Trois, and forward Lucas Moura is injured, which has weakened both their offense and defense. The team has traveled a long way to play at high altitude without proper acclimatization training before the game, so their physical condition will decline significantly. Although they remained undefeated in the group stage, their away - game attacking efficiency is low, and their tactics are rather conservative. In the first leg, they didn't want to take excessive risks to avoid a heavy away defeat that could ruin their chances in the second leg. Based on the above analysis, the home team Bolivar has a greater chance of success in this game.
