Substitute Mikel Merino scored a 91st-minute winner as Spain beat Portugal 1-0 to reach the World Cup quarter-finals, a result that ended Cristiano Ronaldo's tournament career at age 41.
The decisive goal came in front of 70,649 spectators at AT&T Stadium in Arlington, Texas, extending Spain's run without conceding a goal in the tournament. Ronaldo confirmed his retirement from international football following Portugal's exit, likely making this his final World Cup appearance.
Spain now advance to face Belgium, who thrashed the United States 4-1 in a match preceded by controversy involving US President Donald Trump and FIFA. The quarter-final is scheduled for Friday in Los Angeles.
