Spain advanced to the World Cup quarter-finals with a 2–1 victory over Belgium in a dominant knockout display. Operating in a 4-2-3-1 formation, La Roja controlled proceedings with 68% possession and 17 shots, generating 1.96 xG; Mikel Merino and Fabian Ruiz converted their chances to secure the win despite their goalkeeper's modest 50% save percentage across two shots faced. Belgium, restricted to just 32% possession and five shots, offered limited attacking threat with 0.34 xG, though Charles De Ketelaere's goal provided brief resistance. The visitors' goalkeeper made a crucial save above expected performance, posting a 75% save rate on eight shots on target, yet Belgium's defensive vulnerabilities—conceding 2.9 xG—proved ultimately costly. Michael Oliver refereed the encounter without major controversy. Spain's efficiency and possession dominance proved decisive in progressing through the knockout stage.
