Manchester City prodigy makes USMNT debut ahead of 2027 Premier League move

In precisely 12 months, Cavan Sullivan will officially become a Manchester City player.

Whether the exceptionally gifted teenager will integrate directly into the first-team environment, settle into the academy structure, or head out on loan remains uncertain. However, this past weekend offered a preview of exactly what City have secured in the midfielder.

Sullivan, who celebrated his 17th birthday on Monday and will complete his move to City when he turns 18, earned his U.S. Men's National Team debut on Saturday, featuring for 60 minutes in the friendly victory over Peru.

Mauricio Pochettino has handed the midfielder his maiden cap following an impressive stretch of performances in Major League Soccer that has seen Sullivan excel for Philadelphia Union despite being just 16 years old. Since the summer FIFA World Cup intermission, no player has registered more goal contributions than the youngster, with only one individual matching Sullivan's tally of 13—a certain Lionel Messi . Elite company for a talent City secured back in 2024, via the Manchester Evening News .

This campaign has seen the teenager deliver a breakout season that his ability has long indicated was inevitable. Coaches at both club and national team level have been cautious not to accelerate his development prematurely, but his performances this year made him virtually impossible for Pochettino to overlook.

"If we only talk about his performance, he's doing really well in his club in Philadelphia. Talking only about that, I think he's ready, but the rest of the players too," Pochettino said of Sullivan ahead of the weekend win over Peru. "He's mature enough on the field."

Sullivan delivered a poised display in what proved to be a straightforward USMNT win, with numerous emerging talents spearheading the American squad as they set their sights on the 2030 World Cup.

"It was a really special day for me, my family," said Sullivan "It's crazy that I represented my country [with] the highest level with the Men's National Team, so I'm really happy to have done this. Overall, it was a really amazing night.

"There were nerves [and] I was super excited - a little bit of both," he added. "Pregame was definitely nerve-wracking, yeah."

Pochettino declined to comment specifically on Sullivan following the match, instead offering praise for his entire roster. However, it's evident that the teenager has secured his place in the USMNT setup, which faces Chile on Tuesday before taking on Mexico and Canada .

Sullivan is poised to earn additional caps in the days ahead, and his development this season will have delighted City, who fended off interest from numerous elite clubs worldwide to land his signature. He's been regarded as a future star from an early age due to his obvious ability, but those who've worked closely with Sullivan, who still lives at the family home, emphasize that his skill is matched by his mindset.

"A lot of attention goes on the creative things that he brings to the game," said Union interim head coach Ryan Richter , speaking to ESPN . "But the thing that stands out to me the most is his mentality and his competitiveness and the way that he approaches every single day."

Sullivan would do well to learn from Freddy Adu 's trajectory, another teenage sensation dubbed 'the next Pele' when he inked an MLS deal at 14, the same age Sullivan did two decades afterward. Adu was expected to reach the pinnacle, and though he enjoyed a respectable career, the majority of his professional soccer was played domestically, including a stint at Union.

Adu tweeted his congratulations to Sullivan when the future City star surpassed his MLS record as the youngest debutant at 14 years old in 2024. "That's a hard record to break and the kid did it. Well done and good luck my man," read part of Adu's tweet.

Sullivan's challenge next year will be translating his standout performances in America to European competition and City. However, this is a young player who embraces adversity, perhaps unsurprising given he's the youngest of four brothers. He's self-assured yet humble and courteous, and has handled the considerable spotlight he's been under in recent years admirably.

City maintain regular contact with Sullivan and Union to monitor his development and welfare and the player himself is eager about relocating to Manchester . "Man City, what makes the club is the people," said Sullivan earlier this year. He'll soon be part of the family.
