Mauricio Pochettino has signed a two-and-a-half-year deal to take over as Manchester United coach.
United are languishing in 18th place in the Premier League, the worst start in 40 years for the 20-times champions of England.
Pochettino will lead the USA in two matches against Haiti before taking charge of United for the first time against Liverpool at Anfield.
Tears filled Mauricio Pochettino's eyes as he discussed quitting the US national team for his dream job with Manchester United.
"A decision that in some parts, it's a very sad decision, in other parts, we are professional and we need also to try to find the next step, to try and make your dreams come true," he said.
Just three months after the US Soccer Federation announced his contract to lead the Americans through to the 2030 World Cup, Pochettino said he will depart next week for Old Trafford.
The Argentine will try to revive the 20-time English champions, who sit in the relegation zone after 10 games of the Premier League season.
"They know that there's not too many opportunities [that] can happen in your career like a side of Manchester United and, of course, when that arrives, it's difficult to turn down," Pochettino said during an emotional news conference at the US team training camp.
