Mikel Merino scored in the 91st minute to settle a tight Round of 16 tie at AT&T Stadium, sending Spain through and ending Portugal’s campaign after a match shaped more by control, discipline and defensive concentration than attacking fluency. The result extended goalkeeper Unai Simón’s World Cup shutout sequence to 609 minutes, surpassing the 517-minute mark set by Italy’s Walter Zenga in 1990.
Spain’s record run links the closing stages of the 2022 tournament with their 2026 campaign. The sequence began with the goalless draw against Morocco in Qatar, when Spain were eliminated on penalties, and continued this year through a scoreless opener against Cape Verde, group-stage victories over Saudi Arabia and Uruguay, a 3-0 Round of 32 win against Austria and the narrow victory over Portugal.
The achievement gives Spain a defensive distinction unmatched in World Cup history. Italy in 1990 and Switzerland across the 2006 and 2010 editions had each produced five consecutive clean sheets, but Spain’s latest shutout moved them clear. The landmark is notable because the current side are more often associated with possession, midfield rhythm and positional play than low-block defending.
Portugal pressed for long spells without creating enough clear chances. Cristiano Ronaldo forced Simón into two first-half saves, the second after João Félix’s header deflected into his path. Simón adjusted quickly, diving back to gather the effort with both hands. Austria had failed to register a shot on target against Spain in the previous round, but Portugal carried greater individual threat and still found no route through.
Spain’s defensive record has not been built solely on the goalkeeper. Centre-backs, full-backs and midfield screeners have operated with compact spacing, limiting opponents’ access to central areas and forcing attacks wide. The team’s first line of pressure has also reduced the number of direct runs at the back four, making Spain less vulnerable in transition than in some previous tournaments.
Merino’s decisive goal underlined another strength of Luis de la Fuente’s side: impact from the bench. The midfielder arrived late in the box after Spain stretched Portugal across the pitch, finishing a move involving substitutes who added energy after a cagey second half. De la Fuente has repeatedly stressed the value of squad depth, noting after the match that players introduced late have made “enormous” contributions across the campaign.
Portugal’s exit intensifies questions over the future of Ronaldo, who has continued to carry major symbolic weight for his national side. At 41, he remains a focal point, but Spain restricted his touches in dangerous areas and left Portugal reliant on crosses, set pieces and isolated moments. The defeat was a sharp contrast with Portugal’s attacking pedigree, given the squad’s depth in midfield and wide positions.
Spain now move into the last eight with one of the most efficient records of the tournament. Their goals tally has not matched some of the more expansive contenders, but their control of games has been consistent. France, Argentina, England, Morocco, Belgium, Norway and Switzerland have also advanced, creating a quarter-final field in which defensive structure has become as important as attacking star power.
The 2026 World Cup’s expanded 48-team format has added a Round of 32, increasing the physical and tactical demands on leading contenders. Spain have used that longer route to strengthen rather than expose their credentials. Their clean-sheet run through different match types — group-stage control, knockout management and late-game pressure — has made them one of the most balanced teams still standing.
