Members of Team USA are already looking ahead to 2026, when North America will host the next World Cup.

“The future’s really bright for this team,” defender Walker Zimmerman said on “Good Morning America” on Monday.

He added, “So many players from different backgrounds that creates a really unique mix of players. To have the youth that we have -- to have young players playing at high-level teams, we’re going to be coming back stronger in 2026.”

There were highs and lows in Qatar, he said, but it was the honor of a lifetime to play in the World Cup.

Midfielder Kellyn Acosta agreed, saying playing in Qatar had been a “childhood dream become a reality.”

Both said they’d watched footage of fans cheering them back on in the USA. “We appreciate the support,” Acosta said.

But, Zimmerman said, it’ll be nice to be on “home soil” in 2026.

Argentina is headed to the round of 8 after defeating Australia 2-1 in the knockout round.

The win sends Argentina to a quarterfinal match with the Netherlands on Friday. Whichever team wins will proceed to the semifinals.

The U.S. is out of the World Cup after losing 3-1 to the Netherlands in Saturday's knockout round match.

U.S. player Haji Wright's goal in the second half was not enough to hand the team a win. The Netherlands will now move on to the final eight.

Argentina and Australia will face off later Saturday. The winner of that match will play against the Netherlands in the final eight.

At the halftime mark, the Netherlands leads the U.S. 2-0 in the knockout round match.

The winner of the match will move on to the final eight. The loser will go home.

U.S. national team coach Gregg Berhalter tried to keep the focus on Tuesday's game at a press conference as he faced questions about why the U.S. team's Twitter account removed the Islamic emblem from Iran's flag in a post Sunday. He also insisted his team had no knowledge of the post.

The U.S. soccer federation said it removed the logo to show support for those protesting in the country against authoritarian rule and its treatment of women.

Berhalter tried to keep the focus on the uniting power of sports and the World Cup, even as Iran called for the U.S. to be kicked out of the World Cup for altering its flag.

"Sport is something that should bring people together, bring countries together," Berhalter said. "When you look at the Olympics, to see all those countries competing at the same time, is a wonderful event. The World Cup is very similar, where people come from all around the world. Fans come from all around the world, and you get to compete on the field, as brothers, so sport does have the ability to do that."

U.S. captain Tyler Adams was criticized by an Iranian reporter for mispronouncing "Iran," which he apologized for, and he was questioned about discrimination in the U.S., saying it is everywhere but there has been progress. But he also deflected attention back to the game.

"Listen, we support Iran's people and Iran's team. But that being said, you know, we're laser focused on this match as they are as well," Adams, 23, told reporters. "We know how important this is for our progress of our team and what we want to do to prove to our country, you know, how hard we've been working. And we know they want to do exactly the same."

The U.S. must defeat Iran Tuesday to advance to the knockout stage of the tournament.
