The Colombian champions missed out on a great opportunity to advance to the following round of the competition, while Audax Italiano have also kept their chances of advancing intact.Nacional dominated their opponents in the first half, but although they created several good opportunities to take the lead, they couldn’t capitalize on them.Their Chilean midfielder Fernando Martel had a good effort flash inches wide of Mario Villasantti’s left post, and it seemed that Nacional would score at any moment now.Minutes later Carlos Villagra had an opportunity of his own to break the deadlock, but the talented Paraguayan was kept out by Villasantti.After the restart it was much of the same, as the Colombian giants pressed, while the Chileans absorbed heavy pressure.In the 60th minute Nacional finally went ahead, when Sergio Galvan Rey found Villagra with a perfect pass and the midfielder made no mistake, expertly lobbing the ball over Villasantti.But in the 78th minute Fabiano Orellana scored Audax’s unlikely equalizer, when he finished off a swift counterattack.All four teams in the group are still capable of reaching the next round, Nacional, Audax, Sportivo Luqueno, and Sao Paulo. But the two teams who are most likely to advance are Sao Paulo and Nacional.
