Portugal vs Spain Live, FIFA World Cup: (POR 0-1 ESP) Spain send Ronaldo, Portugal packing in R16

Full Time: Portugal 0-1 Spain

It's over in Dallas.

Mikel Merino's stoppage-time winner is enough to send Spain into the World Cup quarter-finals after a gripping contest decided by the finest of margins. Spain created the better chances throughout, while Diogo Costa kept Portugal in the tie until the very end.

Portugal threw everything forward in stoppage time, even sending Diogo Costa into the opposition box, but they could not find a way past Spain's resolute defence.

For Cristiano Ronaldo, it is a heartbreaking end. The final whistle brings the curtain down on his World Cup career, while Lamine Yamal and Spain march on in pursuit of football's biggest prize.

This could have been the moment.

Ferran Torres brings down Francisco Conceicao, giving Portugal one final free-kick to launch into the box. Even Diogo Costa races forward in search of a dramatic equaliser as every Portugal player piles into the area.

The delivery finds Joao Neves, but the midfielder can't keep his effort down, firing wide of the target. A huge chance slips away, and with it perhaps Portugal's hopes of forcing extra time.

Spain make a late sub as they edge closer to the final whistle.

Mikel Oyarzabal replaces Borja Iglesias with Luis de la Fuente looking to see out the closing moments. The message is clear. Spain are focused on protecting their slender lead and managing the remaining seconds.

Portugal have one last chance to throw everything forward.

The breakthrough finally arrives, and it's Mikel Merino once again with a huge knockout goal.

Spain work a clever short free-kick before Fabian Ruiz finds Ferran Torres in space. Torres turns brilliantly on the edge of the box and slips Merino through on goal. The Arsenal midfielder keeps his cool and fires past Diogo Costa at the near post.

After 90 minutes of tension, Spain finally have the lead. Portugal, and Cristiano Ronaldo, now have precious little time to find a response.

Portugal 0-0 Spain | 88'

Bernardo Silva has been on the pitch for only a few minutes, and he's already in Anthony Taylor's notebook.

The Portugal substitute flies into Mikel Merino with a late challenge, leaving the referee with little choice but to brandish a yellow card. It was an unnecessary foul in a tense, finely balanced contest.

With the clock winding down, every tackle now carries extra weight.

Portugal 0-0 Spain | 85'

Luis de la Fuente responds with a double change of his own.

Fabian Ruiz and Mikel Merino replace Pedri and Dani Olmo as Spain inject fresh legs into midfield for the closing stages. It's a like-for-like refresh, but one that adds experience and composure with the match hanging in the balance.

Portugal 0-0 Spain | 83'

Roberto Martinez makes another double change, but one man isn't going anywhere.

Bernardo Silva and Francisco Conceicao come on for Pedro Neto and Vitinha as Portugal freshen up for the closing stages. Fresh legs, fresh ideas and one final push for a winner.

Cristiano Ronaldo remains on the pitch. With extra time looming, Martinez is keeping faith in his captain to produce one decisive moment.

Portugal 0-0 Spain | 82'

Rafael Leao is beginning to make his presence felt.

The Portugal substitute bursts past Pedro Porro with a trademark burst of pace and looks set to whip a dangerous cross into the middle. But the Spain full-back recovers brilliantly, stretching out a boot to block the delivery at the last moment.

A superb piece of defending from Porro. Leao had him beaten, but not for long.

Portugal 0-0 Spain | 79'

Spain are turning the screw now.

Another corner keeps the pressure firmly on Portugal before Mikel Oyarzabal produces a lovely turn inside the box and slips Dani Olmo into space. The midfielder creates just enough room for a shot, but Ruben Dias throws himself in front of it with a huge block.

Portugal are hanging on. Spain have camped themselves in the final third and the pressure is relentless as the clock ticks towards the final 10 minutes.

Portugal 0-0 Spain | 77'

Ferran Torres is straight into the action.

Pedri threads a clever pass down the right and the substitute does well to keep the ball in play before trying to hook it back across goal from a tight angle.

It's the right idea, but the delivery drifts harmlessly into the side netting. Another promising Spain attack ends without a finishing touch.

Portugal 0-0 Spain | 76'

Portugal go close again, and it all starts with Rafael Leao.

The substitute bursts down the left and helps keep the attack alive before the ball skips through to Bruno Fernandes at the back post. The Manchester United captain catches it sweetly, but his fierce strike crashes into the side netting.

For a split second, many inside Dallas thought that was the breakthrough. Portugal are beginning to ask more questions of Spain.

Portugal 0-0 Spain | 75'

Spain make their first change of the afternoon as they look to finally turn pressure into a goal.

Ferran Torres replaces Alex Baena, with Luis de la Fuente opting for fresh legs in the final third. Torres has made a habit of making an impact from the bench and brings direct running and a greater eye for goal.

With Lamine Yamal continuing to trouble Portugal, Spain will hope Torres is the player who finally provides the finishing touch.

Portugal 0-0 Spain | 73'

Lamine Yamal almost produces a moment of magic.

The Spain winger first wins a free-kick on the edge of the area after Nelson Semedo brings him down, raising hopes of a breakthrough. The resulting attack eventually falls back to Yamal, who lets fly from range.

It takes another excellent save from Diogo Costa to keep the scores level, with the Portugal goalkeeper tipping the effort over the crossbar. Costa is putting together a masterclass in Dallas.

Portugal 0-0 Spain | 72'

Roberto Martinez rolls the dice with a double substitution as Portugal look for a breakthrough.

Diogo Dalot replaces Joao Cancelo, while Rafael Leao comes on for Joao Felix, who had been one of Portugal's brightest attacking outlets. Fresh legs out wide could be just what Portugal need as the game enters its decisive phase.

Leao's pace against a tiring Spain defence could prove a fascinating battle over the final 20 minutes.

Portugal 0-0 Spain | 68'

The players head to the sidelines for the second-half hydration break, and both managers have plenty to think about.

The frantic end-to-end football from the opening 45 minutes has given way to a far more tactical battle. Spain are still seeing more of the ball, but Portugal have tightened up defensively and are looking increasingly dangerous whenever Cristiano Ronaldo and Joao Felix break forward.

One mistake could be the difference between a place in the quarter-finals and an early flight home.

Portugal 0-0 Spain | 66'

That was begging to be finished.

Pedro Porro gets all the way to the byline before cutting the ball back into the heart of the Portugal box. It's the perfect cross, but nobody in a Spain shirt has gambled on the run.

The ball rolls through a sea of empty space before Portugal clear. Spain are creating the openings, but they are crying out for someone to attack the six-yard box.

Portugal 0-0 Spain | 61'

Spain are knocking on the door once again.

Dani Olmo works a yard of space with some brilliant footwork inside the box before picking out Pedri on the edge of the area. The Barcelona midfielder strikes first time, but Renato Veiga throws himself in the way to make a vital block and turn it behind for a corner.

Portugal survive the first delivery, but Spain immediately win another corner as the pressure continues to build.

Portugal 0-0 Spain | 59'

Cristiano Ronaldo has another sight of goal, but the finish isn't there.

Joao Felix continues to impress, gliding inside before clipping a delightful cross towards the back post. Ronaldo arrives unmarked and attempts a first-time volley, but can't make clean contact.

The effort trickles harmlessly wide of the near post. Another chance goes begging for Portugal's captain.

This could be a defining moment in the match.

Lamine Yamal finally gets the better of Nuno Mendes, skipping past the Portugal full-back before João Cancelo races across to clean up the danger. But the real concern comes seconds later.

Mendes stays down clutching the back of his leg after stretching desperately in an attempt to recover. It looks like a possible hamstring problem, and his night appears to be over.

Having kept Yamal remarkably quiet for more than an hour, Portugal are now forced into a huge change as Nélson Semedo comes on in his place.

Spain will surely sense an opportunity.

A promising opportunity comes to nothing.

Nuno Mendes shapes as if he's going to take the free-kick, but leaves it for Bruno Fernandes, whose effort never troubles Unai Simón, flying straight into the Spain goalkeeper's gloves.

Portugal had a decent chance to test Spain from a dangerous position, but they'll feel that was one squandered.
