Spain beat Portugal with 91st-minute goal as Ronaldo exits final World Cup

Late drama in Arlington

Spain dominated possession but struggled to break down a resolute Portugal defence until substitute Mikel Merino latched onto Ferran Torres' through ball in the 91st minute and fired past Diogo Costa. The goal sent Spain into the World Cup quarter-finals for the first time since their 2010 triumph and extended their run of clean sheets in the tournament.

Ronaldo's final bow

Cristiano Ronaldo, 41, confirmed before the match that this would be his last World Cup. He played the full 90 minutes, managing three shots and forcing a fine save from Unai Simón, but could not add to his 11 career World Cup goals. After the final whistle, he walked off with a stoic expression, briefly waving to the crowd.

It was my last World Cup, yes, but I'll now have time to reflect and be with my family. I won't be making any rash decisions.

Ronaldo said he leaves with a clear conscience, pointing to Portugal's Euro 2016 title as equally significant to him as a World Cup. He stopped short of confirming his international retirement, saying he did not want a personal decision to overshadow the team.

De la Fuente singles out Yamal

Spain coach Luis de la Fuente praised 18-year-old Lamine Yamal, who started despite a hamstring issue and created constant problems for Portugal's defence. De la Fuente suggested Yamal's pressure may have contributed to Nuno Mendes' injury in the 56th minute.

For me, Lamine has played one of the most important matches of his life. Beyond whether he was brilliant or not, for me it has been one of the matches that will help him grow the most.

Martinez steps down

Portugal manager Roberto Martinez announced his departure immediately after the defeat, saying his contract had expired and that the loss marked the end of a cycle. He praised Ronaldo as an exemplary captain and an icon of the sport.

I came to Portugal to win the World Cup and I think that, without winning it, there's no point in continuing.

What's next

Spain will face either the United States or Belgium in the quarter-finals in Los Angeles. De la Fuente said any opponent at this stage would be a greater challenge than those faced so far.
