Muricy Ramalho's Sao Paulo and Chilean outfit Huachipato will meet in the last 16 of South America's second-tier competition.
Sao Paulo, however, head into Tuesday's opening leg at the Estadio Cicero Pompeu de Toledo on a four-game winless streak in the Brazilian Serie A.
"Quality we have, but we have to show it on the pitch," said Bastos.
"We have another contest, a group of players with a good opportunity to leave behind the latest games.
"We are thinking about the future, which is to win the Libertadores spot and go far in the Copa Sudamericana."
Huachipato were also narrow winners in the second round, downing Ecuador's Universidad Catolica 2-1 over two legs.
Mario Salas' men are sixth in the Chilean Primera Division after eight games, 11 points behind league-leading Universidad Chile.
Huachipato's most recent league fixture was almost a fortnight ago - a 2-2 draw at Antofagasta.
Emelec earned a last-16 showdown with Goias after upstaging Uruguay's River Plate 3-2.
