Atlético Paranaense win on penalties to qualify for the Copa Libertadores group phases
The Brazilian side needed a late comeback to overcome Sporting Cristal in a match that involved four red cards.
Cristal arrived in Brazil with a 2-1 lead after victory in the first leg in Peru.
Both sides lost a player in the 19th minute after Zezinho of Atlético-PR and Cristal's Adan Balbin clashed.
The hosts levelled the tie just after the hour-mark through Manoel but were pinned back just a minute later when Irven Avila's goal put the visitors back in front overall.
Alexis Cossio became the second Cristal player sent off when he received his second yellow card in the 66th minute
Heading into second-half stoppage-time, it looked like the away team would hold on but Marco Ortiz conceded a penalty and was sent off in the 96th minute. Atlético-PR's Ederson stepped up and sent the keeper the wrong way to take the game to penalties.
Cristal slotted its first three penalties to lead 3-2 and when Nathan missed Atlético-PR's fourth spot-kick, it seemed that Cristal would finally secure victory.
They missed the next two attempts, however, while Natanael Pimienta kept Atlético-PR alive and took the shootout to sudden death. The Brazilian side eventually triumphed when Pedro Aquino missed from the spot for the visitors, sending the Paranaense crowd into raptures.
