Mikel Merino delivered a decisive late goal to eliminate Portugal and propel Spain into the FIFA World Cup quarterfinals — their first appearance at that stage since they lifted the trophy in 2010.

The round-of-16 clash on Monday ended with Spain progressing, as Merino's strike proved the difference between the two Iberian rivals. The victory marks a significant milestone for Spain, who have not reached the last eight of a World Cup in 15 years.

Spain's 2010 triumph in South Africa remains the high point of their World Cup history, and Monday's result signals the nation's renewed ambition to challenge for the game's ultimate prize once again.
