BARRANQUILLA, Sept. 3 (Xinhua) -- Colombia manager Nestor Lorenzo said Wednesday his team has a duty to deliver World Cup qualification to its fans with victory over Bolivia in Barranquilla.

A win in the penultimate round of South American qualifiers on Thursday would guarantee Colombia a place at next year's tournament in the United States, Mexico and Canada. Bolivia needs a victory to keep its qualification hopes alive.

"Bolivia is very organized, and I don't think they'll back down," Lorenzo told reporters. "This is a game that could open an important door for us, and we have a responsibility because we're playing at home."

The Argentine coach stressed the need for the Cafeteros to control their nerves as they seek to atone for the disappointment of missing a place at the 2022 World Cup in Qatar.

"You have to manage your emotions, especially anxiety in these cases," he said. "But we have a mature squad, players who have experience in finals and decisive matches."

Lorenzo added that the team could ill-afford to be complacent against a Bolivia side aiming to qualify for football's main event for the first time since 1994.

"We've had a tough time against some teams that we were expected to beat easily," Lorenzo said. "You can never take anything for granted." ■
