Colombian team Once Caldas were held to a goalless draw by Libertad of Paraguay in the first leg of the Copa Libertadores round of sixteen.
The match featured a strongly attacking Once Caldas side, while Libertad clearly arrived to Manizales wanting to defend their goal instead of focusing on the attack.
The tactic worked out for the visitors, who will try to use their home leg to decide the tie in their favor.
The second leg will be played in Paraguay on May 6.
