Merino’s stoppage-time strike ends Ronaldo’s World Cup and sends Spain through

Spain needed every second of a tense last-16 tie to break Portugal down, and when the goal finally came it was a substitute who found it. Mikel Merino met Ferran Torres’s quick free-kick at the near post in the first minute of stoppage time to settle the Iberian derby 1-0 at Dallas, a result that landed in the early hours of the morning in India and carried Spain into the World Cup quarter-finals. It also, in all likelihood, brought the curtain down on Cristiano Ronaldo’s World Cup story.

A cagey derby that refused to open up

For 90 minutes this had the feel of a match neither side wanted to lose more than they wanted to win. Spain controlled the ball and territory throughout, yet Portugal defended their box with the discipline of a team happy to gamble on extra time and penalties. Diogo Costa was the reason it stayed goalless for so long. The Portugal goalkeeper produced a superb double stop midway through the first half, first pushing away Lamine Yamal’s effort after the teenager cut in from the right, then reacting again to keep out Alex Baena’s rebound.

Portugal’s clearest sight of goal arrived just before the interval, and it needed a slice of luck to keep Spain level. Nuno Mendes struck from a set-piece and the ball flicked off Pedro Porro and onto the crossbar, the closest either team came in a first half low on clean chances. After the break Spain kept probing without finding the final pass, and the game drifted toward the knockout lottery Portugal seemed content to invite.

De la Fuente’s substitutions decide it

The breakthrough was built on the bench. Luis de la Fuente had sent on Torres and Merino to freshen Spain’s attack, and the pair combined at the death. Torres caught Portugal napping with a quickly-taken free-kick played low into the box, and Merino, timing his run past his marker, met it first and finished at the near post. Costa had no chance this time. There was barely a minute left for Portugal to respond, and their best effort was a Bernardo Silva header that cleared the bar as the frantic push ran out of time.

For Spain, it was a night that rewarded patience rather than flair. Unai Simon was rarely tested at the other end, and De la Fuente’s side move into the last eight without having produced their best football, which will not trouble a squad that has spent this tournament near the top of the betting.

The end of an era for Ronaldo

At 41, Ronaldo had said before kick-off that this would be his last World Cup, and the game did little to write him a fairytale ending. He finished with 19 touches and three shots, two of them on target without ever seriously threatening Simon. Portugal built plenty around him but could not manufacture the moment their captain needed, and his tournament, and quite possibly his last appearance on this stage, ended with him watching Spain celebrate.

Spain now wait on the winner of the United States against Belgium to learn their quarter-final opponent, with that tie scheduled for later that day. On this evidence they remain hard to beat and harder still to break down, even when the goals refuse to come until the very last act.
