Spain secured a 1-0 victory over Portugal in their World Cup last-16 match, advancing to the quarter-finals where they will face the winner of USA vs Belgium. The decisive goal came in second-half stoppage time from substitute Mikel Merino, who finished a pass from Ferran Torres.

The match was largely devoid of significant attacking moments from either side, with neither nation's numerous stars able to impose themselves until Merino's late strike. Cristiano Ronaldo, playing in what he confirmed was his final World Cup appearance, was unable to inspire his team and registered Portugal's only shot on target.

Spain's victory extends their remarkable defensive record; they are the first team in World Cup history to record six consecutive clean sheets and have not conceded a goal in the current tournament. The loss marked the end of an era for Portugal, with manager Roberto Martinez also confirming his departure after the match, stating his mission to win the World Cup was unfulfilled.

The result means Spain continues their pursuit of a World Cup title, last won in 2010, while Portugal exits the tournament without a fairytale ending for their legendary captain. Ronaldo's international career concludes with him having scored in five different World Cup editions.
