Former Tottenham and Chelsea boss Mauricio Pochettino has been named as the new manager of the United States men's team.
The Argentine replaces Gregg Berhalter, who was sacked in July following the USA's group-stage elimination from the Copa America.
The announcement came before the US drew 1-1 with New Zealand in an international friendly game in Cincinnati.
Pochettino, 52, said it was an opportunity "I couldn't pass up".
"The decision to join US Soccer wasn't just about football for me; it's about the journey that this team and this country are on," he added.
"The energy, the passion, and the hunger to achieve something truly historic here - those are the things that inspired me.
"I see a group of players full of talent and potential, and together we're going to build something special that the whole nation can be proud of."
US Soccer sporting director Matt Crocker led the search for Berhalter's successor and spent time at Southampton when Pochettino was in charge at St Mary's.
"Mauricio is a serial winner with a deep passion for player development and a proven ability to build cohesive and competitive teams," said Crocker.
"His track record speaks for itself, and I am confident that he is the right choice to harness the immense potential within our talented squad."
Pochettino joined Southampton after a stint at Espanyol before moving on to take charge of Tottenham, leading Spurs to the 2019 Champions League final.
He went on to manage Paris St-Germain and Chelsea, leaving the Blues in May after one season in charge in which they finished sixth in the Premier League.
The United States will co-host the 2026 World Cup along with Canada and Mexico.
They are ranked 16th in the world by Fifa, one place below Euro 2024 quarter-finalists Switzerland.
Pochettino's appointment means the US men's and women's teams are both now managed by former Chelsea bosses, after Emma Hayes took charge of the women's team earlier this year.
