A New Generation Arrives: Cavan Sullivan Headlines First USMNT Roster of New Cycle

The United States Men’s National Team has opened a new chapter, and Mauricio Pochettino has made the direction of that new era clear.

When the USMNT announced its first roster following the 2026 FIFA World Cup on Thursday, the biggest story was not simply the return of familiar names. It was the number of new faces. Thirteen of the 28 players selected have yet to earn a senior cap, with an average age of just 19 years and six months.

At the center of that group is Cavan Sullivan, the 16-year-old Philadelphia Union sensation who has earned his first senior call-up after a spectacular summer in MLS. But Sullivan is far from the only teenager or young prospect being introduced to the national-team environment.

Sullivan’s inclusion was the most anticipated.

The Philadelphia native has transformed himself from an exciting teenage prospect into one of the most productive young players in MLS during the second half of the 2026 season. Since the Union returned from the World Cup break, Sullivan has recorded six goals and five assists in 12 appearances, including a spectacular backheeled goal against San Diego FC and a two-goal, one-assist performance in the same 5-0 victory.

His form has coincided with Philadelphia’s dramatic turnaround, and Pochettino’s staff has been watching closely.

Now Sullivan has his first invitation to the senior national team, just days before his 17th birthday.

If he makes his debut during the upcoming window, he would become one of the youngest players ever to appear for the United States. His arrival also adds another remarkable chapter to a career that already includes the record for the youngest MLS debut in league history. 

Sullivan is joined by Neil Pierre and Frankie Westfield, giving the Philadelphia Union three players in the squad who are making their senior-team debut at the international level.

Pierre, 18, is one of the most intriguing young center backs in the American player pool. Standing at 6-foot-7, the Lebanon, Pennsylvania native has made an immediate impression after breaking into Philadelphia’s first team, combining his physical presence with a strong passing range.

He has also already demonstrated an ability to contribute in the final third, scoring four headed goals since joining the Union’s senior team this summer. His call-up comes with an eye toward both the senior national team and the 2028 Olympic cycle, for which he remains age eligible. 

Westfield, meanwhile, gives Pochettino another young option at fullback. The 20-year-old Philadelphia native has progressed through the Union system and established himself as another member of the club’s impressive homegrown pipeline.

The roster also includes two young players from Red Bull New York: Adri Mehmeti and Julian Hall.

Mehmeti, only 17, has become one of the youngest players in the MLS player pool and now gets an opportunity to train alongside established USMNT midfielders.

Hall is already a familiar name to followers of American youth soccer. The forward broke into New York’s first team at a remarkably young age and has continued to develop within one of MLS’s most established youth pathways.

Justin Ellis of Orlando City is another uncapped player included in the squad.

His selection is particularly interesting because Pochettino specifically identified Orlando, Philadelphia, New York and several other MLS clubs when discussing the young players he had been monitoring before the roster announcement.

Ellis now gets the chance to make that impression directly within the senior environment.

Another name that deserves attention is Brooklyn Raines.

The New England Revolution midfielder has progressed through the club’s development system and now receives his first senior call-up at a crucial stage of his development.

Raines has already been involved extensively with U.S. youth national teams, and his inclusion reflects the importance Pochettino is placing on players who have accumulated international experience at younger age groups but have yet to make the jump to the senior level.

Schwake, meanwhile, earned his opportunity after an impressive season with Nashville SC. His selection gives Pochettino another young goalkeeper to evaluate in a position where the United States will need to develop long-term depth.

The uncapped group is not limited to MLS.

Mathis Albert, a young midfielder in the Borussia Dortmund system, has received his first senior call-up after progressing through the German club’s academy structure.

Zavier Gozo, meanwhile, has earned his opportunity after an impressive MLS season with Real Salt Lake before his move to Crystal Palace. The 19-year-old had six goals and four assists in 16 MLS appearances in 2026 and was selected for the MLS All-Star Game before making his move to England. U.S. Soccer has previously highlighted his experience with the U.S. youth national teams, including the 2024 Concacaf U-20 Championship and 2025 U-20 World Cup. 

There is also Cole Campbell, another young American playing in Germany, who has been called into the senior team for the first time.

The youth movement extends to the goalkeeping position.

Kochen, who plays for Lyngby in Denmark, has been part of the U.S. youth national-team setup and has long been viewed as one of the more intriguing young American goalkeepers developing in Europe.

The youth movement does not mean Pochettino has completely abandoned the players who represented the United States at the World Cup.

The roster still contains established internationals such as Tyler Adams, Antonee Robinson, Chris Richards, Sergiño Dest, Miles Robinson, Gio Reyna, Malik Tillman and Ricardo Pepi. Yunus Musah also returns to the group after being absent from the World Cup squad.

That combination gives the younger players a chance to enter an established international environment rather than being asked to carry the team immediately.

And some major names are missing. Christian Pulisic, Weston McKennie and Folarin Balogun were not included, making the generational shift even more visible.

For Pochettino, however, this is the beginning of a four-year process rather than a definitive reshaping of the national team.

The United States will play Peru, Chile, Mexico and Canada during the September-October window, giving the coaching staff four matches to evaluate this group. 

Now they have to show they belong.

And while Cavan Sullivan naturally attracts the most attention at 16, this roster makes one thing clear: the next generation of American players is no longer waiting outside the USMNT. They have been invited in.
