Philadelphia Union midfielder Cavan Sullivan is expected to receive his first call-up to the United States men’s national team later this month, according to an unnamed source familiar with the selection process. The U.S. team will face Chile, Peru, Mexico, and Canada in late September and early October. The final roster is anticipated to be announced by head coach Mauricio Pochettino on Thursday morning. ESPN’s Jeff Carlisle was the first to report that Sullivan will be included in the squad. Sullivan, who turned professional at age 14, has long been considered a rising star with potential for international recognition. His performance in Major League Soccer (MLS) since the league resumed play after the summer World Cup has been impressive, with six goals and eight assists in that timeframe. This strong showing has caught the attention of Pochettino, who has been evaluating players for the upcoming matches. Earlier this month, Pochettino hinted that Sullivan had demonstrated value for the U.S. team during the World Cup, where the squad was eliminated in the last-16 round by Belgium. “We are watching everything, we are seeing everything,” Pochettino told reporters at the time. “And of course, we want players with talent, players that feel brave, feel confident, but not [that] feel things that they still don’t show or they [haven’t] earned.” If Sullivan earns a spot in this upcoming international window, he will become the second-youngest player to represent the U.S. men’s national team (USMNT), following Freddy Adu, who was slightly younger when he debuted in a 2006 friendly against Canada. Sullivan also made history earlier this year by becoming the youngest player in the history of any major North American professional sport to appear in a match, when he made his debut for the Union in 2024. He signed with the Union in May 2024, and his contract includes a clause that could lead to a transfer to Manchester City when he turns 18.
