Wonderkid Alert: 16-Year-Old Cavan Sullivan Poised for First USMNT Call-Up as Pochettino Finalizes Four-Game Slate

American soccer's most hyped teenager looks ready for his close-up. Cavan Sullivan, the 16-year-old Philadelphia Union midfielder whose precocious talent has made him one of the most talked-about young players in world football, is set to earn his first call-up to the United States men's national team later this month, a source with knowledge of the roster told the Guardian on Wednesday. The source requested anonymity because they were not authorized to discuss the squad ahead of its official release. The call-up arrives at a pivotal moment in the USMNT's buildup to the 2026 World Cup, which the Americans will co-host alongside Mexico and Canada. Fittingly, the upcoming window reads like a dress rehearsal for next summer's tournament: the US will face Chile, Peru, Mexico and Canada across late September and early October, testing itself against a mix of South American opposition and the two nations sharing hosting duties in 2026. Head coach Mauricio Pochettino is expected to announce his roster on Thursday morning, and ESPN's Jeff Carlisle was first to report Sullivan's inclusion. For the Argentine manager, handing a first senior summons to a player who cannot yet legally drive in some states would be a bold statement about his willingness to reward form and fearlessness over pedigree. And Sullivan's form demands attention. The Union homegrown standout has been electric in the period since the World Cup, racking up six goals and eight assists while tormenting defenders twice his age. His vision, close control, and composure in tight spaces have drawn comparisons to some of the game's elite creators, and his rapid development has made him virtually impossible for national team brass to ignore. The four-match window offers Pochettino a valuable audition stage less than a year out from the World Cup opener. Matches against Chile and Peru provide a taste of CONMEBOL physicality and craft, while reunions with Mexico and Canada carry the spice of regional rivalry — and a sneak preview of the co-host dynamic that will define the tournament itself. For Sullivan, simply training alongside the senior squad would mark another milestone in a career that has moved at breakneck speed. Whether he features on the pitch or absorbs the experience from the bench, the message is clear: the road to 2026 runs through the next generation, and Pochettino is not afraid to fast-track it. American fans, mark Thursday morning on your calendars. The Cavan Sullivan era may be starting sooner than anyone expected.
