American hopes for a deep World Cup run at home ended when Charles De Ketelaere scored twice and assisted on another goal, helping Belgium expose the U.S. defensive liabilities in a 4-1 win Monday night that earned a quarterfinal berth.

“It stinks,” Tyler Adams said. “This was a moment to have an opportunity to advance and really try and do something special. We fell short.”

While the U.S. was boosted by the presence of star forward Folarin Balogun, whose one-game red-card suspension was controversially lifted by FIFA, American defenders were at fault in a pair of first-half goals and Freese’s howler gave the Red Devils a third early in the second half.

Second-half substitute Romelu Lukaku added Belgium’s final goal in the third minute of stoppage time after Richards’ giveaway. The U.S. hadn’t allowed that many goals in a World Cup game since a 5-1 loss to Czechoslovakia in the Americans’ 1990 opener, when they returned to soccer’s biggest stage after a 40-year absence.

“A very bad day,” said Pochettino, the U.S. coach. “It’s not like you are in a rocket and you improve and you grow. … It’s not linear.”

This loss was a painful reckoning for a team that hoped to boost the sport but instead failed to shake a quarter-century of stagnation since 20-year-old Landon Donovan led the Americans to the 2002 quarterfinals. Since then, the U.S. has lost four times in the round of 16.

“Everyone had nerves, right, because we knew how much this meant for the whole country, not just our team,” said 21-year-old defender Alex Freeman, the youngest U.S. player.

Belgium knocked out the U.S. in the round of 16 for the second time in 12 years and extended its unbeaten streak to 18 games. The Red Devils play 2010 champion Spain on Friday at Inglewood, California, for a semifinal berth against France or Morocco.

“We showed that we’re ready and we want to perform,” captain Youri Tielemans said.

All six CONCACAF nations have been eliminated, with the three co-hosts falling in the round of 16.

Malik Tillman tied the score 1-1 midway through the first half when he became the first player since France’s Bernard Genghini in 1982 to have two free kick goals in a World Cup, but the Americans conceded just 61 seconds after the ensuing kickoff.

American star Christian Pulisic could only watch the end from the bench after injuring his right ankle when he hit Tielemans’ boot on a 52nd-minute shot attempt. Pulisic was replaced seven minutes later, finishing the tournament with no goals.

“I didn’t quite have the moments I was hoping to and to try to help us to really push and get over this next step of beating a really good team,” he said. “I’m disappointed with myself, of course, but I’m going to try and stay positive. I did a lot of good things and the team did, as well.”

After winning three World Cup games for the first time in this expanded 48-nation tournament, the U.S. lost its seventh straight match to Belgium. The Americans have dropped 11 of their last 12 games against European opponents, winning only their round of 32 match against Bosnia-Herzegovina.

A heralded generation led by Pulisic, Adams and Weston McKennie only partially accomplished their mission of lifting soccer’s stature closer to that of the NFL, MLB and the NBA.

“A goal was obviously to inspire people that the sport was growing in the U.S., which I think we saw. The support was unbelievable,” Adams said. “In this moment we let them down.”

De Ketelaere put Belgium ahead in the eighth minute and Tillman’s goal in the 31st energized a largely red-white-and-blue crowd of 66,925 at Lumen Field. De Ketelaere damped that and assisted on Hans Vanaken’s 57th-minute goal after Freese lost control of the ball in front of his net.

“Obviously disappointed for my involvement and error in judgment on the third goal,” Freese said.

Belgium, which didn’t start stars Jérémy Doku as and Kevin De Bruyne, pressed from the start and exposed a defense regarded as the Americans’ weak spot.

Dodi Lukébakio made a long diagonal pass to the opposite corner, leading to the opening goal. Leandro Troussard controlled the ball and his cross was blocked by Freeman and popped into the air. Freeman headed the ball into the penalty area and Timothy Castagne charged after it and hooked a centering pass around Richards. De Ketelaere split Antonee Robinson and Tim Ream, at 38 the oldest American ever in a World Cup, then with his right foot redirected the ball into an open net.

Pochettino held out his arms, as if to ask: What was going on?

Tillman scored after Brandon Mechele knocked down Balogun about 25 yards from goal. Tillman’s kick deflected off Vanaken’s head and deflected to the left of goalkeeper Thibaut Courtois, who had dived right.

Troussard got around Sergiño Dest for a cross and De Ketelaere outjumped Ream and headed the ball past Freese in the 33rd minute for his eighth international goal.

Belgium built a two-goal lead when Mechele lofted a long ball that Freese chested after two hops. Freese hesitated with a touch, then scrambled and kicked the ball off De Ketelaere. Vanaken one-timed a shot from 35 yards that deflected in off Ream.

Lukaku entered in the 67th minute and scored his 93rd international goal.

Pochettino replaced Gregg Berhalter after first-round elimination at the 2024 Copa America. His contract expires this summer and he hasn’t decided whether to stay through the 2030 World Cup.

Instead of focusing on Spain, Pochettino has a different near-term agenda.

“To rest a little bit, to think, to have conversation,” he said, “and then see what the decision is from the federation and from us.”
