Before the 2002 FIFA World Cup, Paraguay manager Cesare Maldini had faced criticism in Paraguay, but Chilavert defended Maldini for his experience. He also expressed great confidence in the ability of the Paraguayan team and downplayed his role on the team. During the World Cup, Chilavert made an error against Spain on Morientes's 2–1 goal as Paraguay lost 3–1. Chilavert almost redeemed himself later with a good free kick attempt, but the shot was saved by Casillas. Before the match, Chilavert had vowed to score against Spain if Paraguay got a free kick "within range". Before the last match in the group stage, Paraguay had to beat Slovenia and Spain had to beat South Africa, with a combined margin of three goals, for Paraguay to go through to the last 16. The match started badly for Paraguay, with Carlos Paredes sent off in the 21st minute, and continued with Milenko Ačimovič taking the lead for the Slovenians right before half-time. But Paraguay – inspired by substitutes Nelson Cuevas and Jorge Campos – recovered to defeat Slovenia 3–1, scoring three times in the last 25 minutes, and when Spain also defeated South Africa 3–2, that victory meant that Paraguay was through to the next round, where they would play Germany. In their second-round match against Germany, despite several saves from Chilavert, Paraguay lost 1–0, courtesy of a late Oliver Neuville goal.
