Argentina's path to defending its World Cup crown continues to be anything but straightforward.

For the third consecutive knockout match, Lionel Scaloni's side found itself pushed to the brink before discovering another dramatic escape, defeating a resilient Switzerland 3-1 after extra time on Saturday night at Kansas City Stadium to book a heavyweight semifinal clash with England.

Julián Álvarez delivered the defining moment of the evening, unleashing a spectacular curling strike from distance in the 112th minute to finally break Swiss resistance. Lautaro Martínez added a third in stoppage time of extra time, converting after Thiago Almada's effort was saved, but the final scoreline hardly reflected a contest that hung in the balance for more than two hours.

Argentina had started brightly, opening the scoring after just 10 minutes. Lionel Messi's inswinging corner found Alexis Mac Allister, who rose above a crowd of defenders to glance a header into the far corner and hand the defending champions an early advantage. It was Messi's 10th World Cup assist, extending another remarkable chapter in his tournament legacy even as his record nine-match World Cup scoring streak came to an end.

Yet Switzerland, appearing in its first World Cup quarterfinal since 1954, refused to fade. After weathering Argentina's early pressure, Murat Yakin's side gradually grew into the match, forcing Emiliano Martínez into several important saves before finally finding a deserved equalizer in the 67th minute. Dan Ndoye exchanged passes with Ricardo Rodríguez before calmly sliding his finish past Martínez, silencing the sea of Argentine supporters inside the stadium.

The turning point arrived moments later in controversial fashion. Initially, Leandro Paredes appeared destined for a yellow card following a challenge on Breel Embolo. But after a VAR review under FIFA's "mistaken identity" protocol, officials determined Embolo had simulated the contact. Already carrying a booking, the Swiss forward instead received a second yellow card and was sent off, leaving Switzerland to battle the final stages with 10 men.

Even with the numerical advantage, Argentina struggled to break through. Messi curled one effort inches wide in stoppage time, while Gregor Kobel continued to frustrate La Albiceleste with a string of crucial saves. Penalties loomed until Álvarez seized the moment, collecting the ball outside the area before bending an unstoppable effort into the top corner to send Kansas City into celebration.

"We kept trying until the end," Álvarez said afterward. "We knew that if we stayed together, the goal would come."

Martínez's late finish added gloss to the result, but Argentina knows the performance left room for improvement. Scaloni admitted his side "suffered" against a physical Swiss team and acknowledged the dismissal shifted the momentum.

The reward, however, is another semifinal appearance—and a tantalizing showdown with England. Alongside France and Spain, the world's top four ranked nations have all reached the final four, setting the stage for one of the strongest semifinal lineups in World Cup history.

Argentina may not be making this journey easy, but they continue to find a way. With two matches left, their title defense remains alive.
