Cristiano Ronaldo’s quest to win the FIFA World Cup came to a heartbreaking end after Portugal suffered a dramatic 1-0 defeat to Spain in the Round of 16 of the 2026 tournament, with substitute Mikel Merino scoring a stoppage-time winner to send the European champions into the quarter-finals.

In what is expected to be Ronaldo’s final World Cup appearance, the 41-year-old was unable to inspire Portugal past their Iberian rivals despite playing the full match. The Portuguese captain endured a frustrating evening as Spain’s disciplined defence kept him largely quiet, bringing the curtain down on his remarkable World Cup journey.

Spain, who were far from their fluent best, struggled to break down a resilient Portuguese side for much of the contest. However, just when extra time appeared inevitable, Merino came off the bench to deliver the decisive blow, firing home in stoppage time to spark wild celebrations among the Spanish players and supporters.

The victory sees Spain advance to the quarter-finals, where they will face Belgium on Friday in a blockbuster showdown for a place in the last four.

For Portugal, the defeat marked the end of an era. Head coach Roberto Martínez stepped down immediately after the match, bringing his tenure to a close following another painful World Cup exit.

Ronaldo leaves the tournament with his dream of lifting football’s biggest prize unfulfilled, despite a glittering international career that includes the UEFA European Championship, UEFA Nations League title, and numerous individual records.

While Spain continues their pursuit of another World Cup crown, the spotlight now turns to Ronaldo’s legacy—one of the greatest players in football history whose extraordinary career will forever be remembered, even without the World Cup trophy that eluded him.
