Goals from Jo and Leonardo Silva helped Atletico Mineiro overturn a 2-0 first leg deficit to win the continental cup for the first time.
Atletico Mineiro was 2-0 down heading into the second leg of the final, but strikes from Jo and Leonardo Silva sent the game into extra time, with the home crowd cheering the Brazilian side to its first triumph in the continental tournament.
"Today Atletico is a winning club," Cuca told reporters. "No one can say the opposite. Especially after all we’ve been through in this competition.
"We saved a penalty kick in the 93rd minute [of the quarterfinal win over Tijuana], we won in shootouts, we lost 2-0 in two first legs including in the final, so today this changed.
"We have changed a club history. A century-old club that now is a lucky club. And so am I. We haven’t realized this achievement yet. It is too much. We are all numb at this moment. But we have to be thankful.
"We’ve managed the first-leg defeat quite well, as we did against Newell’s as well. We worked on our emotional side during the week keeping everybody positive and faithful.
"We did everything right. The match was really tense because we are all human beings. We felt the obligation of winning this trophy for the first time, so it was hard to keep our patience and composure in the final."
Mineiro became the fourth consecutive Brazilian club to win the competition, following in the footsteps of Internacional , Santos  and Corinthians .
