Merino, who had come on in the 85th minute, ghosted in behind Portugal's defense to finish a Ferran Torres pass in the 91st, ending a tight, chance-starved Iberian derby.The result eliminates Ronaldo, 41, from soccer's biggest stage for good, since he had already confirmed this would be his final World Cup appearance. Spain, unbeaten and still without conceding a goal in the tournament, advances to face the winner of the USMNT-Belgium match in the quarterfinals.Cristiano Ronaldo leaves the World Cup stadium in tearsPortugal's Cristiano Ronaldo (7) reacts after the World Cup round of 16 soccer match between Portugal and Spain in Arlington, Texas, near Dallas, Monday, July 6, 2026. (AP Photo/Julio Cortez)Cristiano Ronaldo played all 90 minutes and finished with just three shots, two on target, unable to beat Spain goalkeeper Unai Simón. After the final whistle, he wiped away tears while applauding fans at the stadium. Speaking to reporters afterward, he said he was "sad to leave the World Cup this way," adding that he was moving forward with a clear conscience and would take time with family before deciding on his international future. Ronaldo's tournament ends with 11 career World Cup goals and 27 appearances, second only to Lionel Messi's 30. He remains the only player to score in six different World Cups, having netted three goals in this edition, including a brace against Uzbekistan and a penalty against Croatia. His deepest World Cup run came in 2006, a semifinal appearance in his debut tournament. He won Euro 2016 and two Nations League titles with Portugal, but the World Cup trophy stayed out of reach.CategoryCristiano Ronaldo (World Cup career)Tournaments played6Total appearances27Total goals11Best finishSemifinal (2006)Trophies won with PortugalUEFA Euro 2016, 2 UEFA Nations League titlesPortugal head coach Roberto Martínez also announced his departure after the match, saying the team needed a "new voice" following the elimination.
