South Korea lost 4-1 to Uruguay in a men's national-team friendly at Seoul World Cup Stadium on September 28. The result came four days after Korea beat Ecuador 3-0, exposing a sharp swing in performance under coach Roberto Moreno.
Uruguay scored early and repeatedly broke through Korea's defensive organization, while Son Heung-min provided Korea's lone goal. The match drew about 48,000 spectators and leaves the national team with clear defensive issues to address before its next fixtures.
