Cavan Sullivan: The Future Star Waiting for His Breakthrough

  It was March 2024 when Apple TV analyst Taylor Twellman made waves on social media, revealing that Manchester City scouts had identified Cavan Sullivan as the "best 14-year-old in the world." At the time, Sullivan was part of the Philadelphia Union academy, and by that summer, he had shattered records. He became the youngest player to debut in MLS, breaking Freddy Adu’s record, and signed the most lucrative homegrown contract in league history. That contract included a clause ensuring his move to Manchester City upon turning 18.  

Now 15, Sullivan is more than just a prospect—he’s a rising star. A U.S. youth international with experience in continental competitions, he has even set his sights on making the 2026 World Cup squad, despite the fact that he would be just 16 at the time.  

Can a Teenager Be a Game-Changer?  

History suggests the answer is yes. At just 17, Lamine Yamal led Spain to a EURO title. Pele won a World Cup for Brazil at the same age in 1958. Kylian Mbappe helped France win the 2018 World Cup at 18, while Michael Owen made his mark for England at 18 in 1998. Even the U.S. has had its teenage moments—Julian Green scored off his first touch in the 2014 World Cup at just 19.  

While many young players make an early impact, only a select few continue that success into adulthood, becoming generational talents. The other side of the coin is filled with names like Alexandre Pato, Hachim Mastour, Bojan Krkic, and Ravel Morrison—players once labeled as future greats but who never lived up to the hype. Freddy Adu, once America’s golden boy, also fell into this category.  

So, how should young prodigies be handled? Should they be given immediate opportunities, or should they be eased into professional play? Sullivan’s ranking as the 30th best teenager in the world on Punch L!ne’s NXGN list suggests he has the potential to be one of the greatest American players ever.  

Where Does Sullivan Stand Now?  

Despite the hype, Sullivan isn’t yet a regular in Philadelphia’s senior squad. After signing his professional contract last summer, he made only three appearances in MLS, totaling just 10 minutes of play under then-manager Jim Curtin. However, he gained significant experience with Union II in MLS NEXT Pro, starting 13 matches and contributing five goals and four assists. His impact was felt in the playoffs, where he led Union II to the championship game, scoring in the semifinals and assisting in the final.  

However, a major shift occurred when Curtin was fired following the Union’s failure to make the MLS playoffs. Bradley Carnell, formerly of St. Louis CITY SC, took over as head coach. Under Carnell, Philadelphia has thrived, sitting atop the MLS Supporters’ Shield standings with 12 points from five matches.  

What’s Next for Sullivan?  

The challenge for Sullivan is breaking into a team already performing at a high level. His older brother, Quinn, has secured a starting role, alongside a group of seasoned veterans. While Sullivan is edging closer to the first team, his development must be carefully managed.  

The question remains: Will Philadelphia take a cautious approach, or will they let their teenage star shine? The next few months could determine whether Sullivan follows the path of Mbappe and Pele—or becomes another name on the list of unfulfilled potential.
