Mauricio Pochettino is confident the United States have an "amazing future" ahead of them after his penultimate game in charge ended in a 6-0 rout of Haiti.
The Argentine is departing his role as USMNT head coach following the conclusion of the Nations League quarter-final tie to replace Michael Carrick at Manchester United.
USMNT took a huge step towards the semi-finals at Nu Stadium in Miami, which was actually USA's away tie due to ongoing security fears in Haiti, with star man Christian Pulisic scoring twice.
Auston Trusty, Julian Hall, Weston McKennie, and Folarin Balogun were also among the goalscorers in the resounding rout.
Speaking after the game, Pochettino said: "I think we have an amazing future, brilliant future in this country with the national team.
"I think if we want to go for big things, that is in the way of the construction of the structure and the principles I think are here now and it's only continuing."
Former Tottenham and Chelsea boss Pochettino is headed straight for Manchester to begin his role at Old Trafford following the second leg in Cincinnati on Tuesday.
The 54-year-old credited his side for not letting news of his departure overshadow the task at hand.
Pochettino added: "They were very, very professional from day one when they started to see all the rumours and then when we confirmed it a few days ago.
"And I think if you say to me, what we feel proud of, we feel so proud of the players and how they manage the situation in a mature way.
"In the last two years, the kids, the young kids that appear and you can see how they play very relaxed because of what the experienced players provide, that platform to perform."
Pulisic was playing his first game for the national team since the World Cup, and he has now moved ahead of Eric Wynalda to fourth on USA's all-time leading goalscorer list with 35 in 91 outings.
The winger had sustained a microfracture to the right tibia and fibula in the 4-1 loss to Belgium at the World Cup, but was back with a bang on the international stage.
Pulisic said he can understand why Pochettino has made the decision he has.
"I think he has a big opportunity there and yeah, we just have to continue as we're doing and try to continue to grow as a team," Pulisic said.
"I think we had some good moments, and he brought a lot of excitement to the team. So I think he'll leave that behind."
