Spain advanced to the World Cup semifinals with a 2-1 victory over Belgium at Los Angeles Stadium, courtesy of an 88th-minute strike by Mikel Merino. While superficial match reports will highlight Merino’s history-making intervention from the bench, the true narrative of this quarterfinal hinges on a cascading series of physical failures, tactical gambles, and a cruel goalkeeping tragedy.
Spain controlled the ball but struggled to pierce a deeply organized Belgian block, opening the scoring through Fabián Ruiz in the 30th minute before Charles De Ketelaere equalized just before halftime. The balance of power dissolved entirely when Belgium's talismanic goalkeeper, Thibaut Courtois, suffered a severe leg injury in the 71st minute. His replacement, 24-year-old debutant Senne Lammens, committed the catastrophic handling error that gifted Merino his second consecutive tournament-winning goal.
The Chaos Before Kickoff
Elite tactical preparation matters little when the human body betrays a squad minutes before the whistle. Rudi Garcia’s tactical blueprint for Belgium was already compromised by the loss of Amadou Onana to an ACL tear earlier in the summer, forcing heavy reliance on Youri Tielemans to stabilize the central channel.
Then came the warmup.
Tielemans sustained a sudden muscle injury during pre-match drills, forcing Garcia to thrust Hans Vanaken into the starting XI against arguably the most formidable midfield trio in modern football. This late alteration disrupted Belgium's defensive spacing, leaving Nicolas Raskin isolated trying to track Dani Olmo and Rodri. Spain manager Luis de la Fuente noticed the structural imbalance immediately. Recognizing that Pedri might lack the physical engine to punish a scrambled Belgian midfield over 90 minutes, de la Fuente made a calculated alteration of his own, handing the starting nod to Fabián Ruiz.
The adjustment yielded dividends within the half-hour mark. Lamine Yamal, operating with a noticeable limp due to a lingering hamstring issue, dragged Maxim De Cuyper out of position before slipping a pass to Pedro Porro. Porro’s subsequent delivery found Olmo at the edge of the area. Courtois made a sprawling stop on Olmo's initial effort, but the structural failure in Belgium's midfield left Ruiz completely unmarked to smash home the rebound.
The Doku Sacrifice and the Belgian Response
Garcia’s response to the opening deficit revealed the tactical maturity of this Belgian generation. Instead of letting Jérémy Doku roam high up the pitch as an isolated counter-attacking outlet, the Manchester City winger was instructed to drop deep, effectively forming a double-layer defense with De Cuyper to neutralize Yamal.
It was an exhausting, unglamorous assignment. Doku frequently tracked back into his own penalty box, physically harassing Yamal and blocking lanes of interior progression. This tactical selflessness stabilized the left flank and generated the platform for Belgium’s equalizer.
In the 41st minute, Kevin De Bruyne found an inch of space behind Rodri, weighting a pass perfectly into the path of an overlapping Timothy Castagne. Castagne’s cross was sharp, targeted directly at the gap between Pau Cubarsí and Aymeric Laporte. Charles De Ketelaere met the ball with a powerful header, snapping Spain’s remarkable run of six consecutive World Cup clean sheets and shattering Unai Simón’s 650-minute unbeaten streak.

The Injury That Altered History
The second half settled into a grueling war of attrition. Spain monopolized possession but their possession grew sterile, repeatedly checked by the disciplined positioning of Nathan Ngoy and Brandon Mechele. De la Fuente threw on Ferran Torres and Pedri to inject tempo, yet Courtois remained largely untroubled, marshaling his box with veteran composure.
Everything changed on a routine clearance.
In the 71st minute, after coming out to claim a dangerous cross aimed at Mikel Oyarzabal, Courtois landed awkwardly on his left leg. The Real Madrid shot-stopper attempted to play through the discomfort, but as the match paused for a second-half hydration break, he collapsed to the turf in visible agony.
The image of Courtois being helped off the pitch in tears signaled the end of an era for Belgium’s golden generation. It also forced Senne Lammens, a backup keeper with zero minutes of international tournament experience, into the ultimate crucible.
The Cruel Geometry of the Rebound
International football is merciless to the uninitiated. For 15 minutes, Lammens looked protected by his veteran backline as Belgium dropped into a low block, aiming to drag the match into extra time where Romelu Lukaku's late introduction could exploit an exhausted Spanish defense.
Then Pau Cubarsí stepped up from central defense.
Seeing no immediate passing lane through the Belgian low block, the young Barcelona defender unleashed a speculative, low drive from 30 yards out. It was a shot Courtois would have gathered into his chest nine times out of ten. Lammens, caught slightly out of position and lacking the necessary footwork adjustments, failed to secure the ball cleanly. The ball spilled off his palms directly into the path of Mikel Merino.
Merino had been on the pitch for less than 120 seconds, brought on in the 86th minute to replace Dani Olmo. His anticipation was instantaneous. The Arsenal midfielder ghosted past a static Mechele and lashed the loose ball into the roof of the net.
With that single touch, Merino secured his place in soccer history. He became the first player ever to score the winning goal as a substitute in two separate knockout matches at a single World Cup, repeating his late heroics against Portugal from the previous round. It is a testament to de la Fuente's squad depth, but an absolute tragedy for a Belgian side that had executed its defensive game plan to near perfection.
The Midfield Vacuum Ahead
Spain’s 36-match unbeaten streak remains intact, and their semifinal date with France in Dallas promises a tactical showcase. However, the celebration in Madrid will obscure real tactical red flags. Spain struggled to convert 62% possession into clear-cut opportunities against a depleted Belgian midfield missing its primary anchors.
Against France, the luxury of waiting for an opposing goalkeeper to make a catastrophic error will not exist. De la Fuente must address why his starting frontline looked entirely toothless when Yamal was successfully double-teamed. The victory is historic, but the structural cracks in the Spanish attack are wide open for Didier Deschamps to exploit.
