Cavan Sullivan: MLS’s Youngest Star Looks Toward Europe

Cavan Sullivan burst onto the professional scene when he debuted for the Philadelphia Union at 14, becoming the youngest player ever to appear in Major League Soccer and surpassing Freddy Adu’s long-standing record. After two years largely on the bench, he earned a regular starting role this summer and has already attracted a pre-contract with Manchester City that will activate on his 18th birthday.

Sullivan accounts for 10.3 % of the Union’s touches—the highest share among teenage MLS wingers in the past decade, second only to Alphonso Davies in the league’s history. In the 2026 season he has logged four goals and three assists in MLS play, matching those totals across all competitions. Advanced metrics show a 0.48 expected-goals-and-assists per 90 minutes rate, ranking fourth among MLS teens with at least 1,000 minutes, and a futi player-rating that places him second-best ever for an MLS teenager, behind only Gianluca Busio. His passing completion sits at 65 %, comparable to the Union’s overall rate, while he records 5.0 progressive passes per 90 minutes, placing him in the top five wide attackers league-wide.

Classified by the futi model as a “wide playmaker,” Sullivan prefers to receive the ball near the touchline, dribble past defenders, and create scoring chances for teammates. He averages 6.2 progressive receptions per 90 minutes and relies heavily on skill moves reminiscent of his childhood idols Lionel Messi and Alexis Sánchez. Although his turnover rate is high, the Union tolerates the risk given his ability to generate dangerous passes and occasional “crazy lob” attempts.

Union head coach Jim Curtin highlighted the early trust shown to Sullivan, noting that teammates handed him the ball within ten seconds of his first training session—a gesture he described as “the ultimate sign of respect.” Curtin has emphasized Sullivan’s vision and decision-making as key assets for the team.

At 5 ft 7 in, Sullivan is smaller than most Premier League wingers; only 15 players in the league last season were his height or shorter, with Enzo Le Fée being the sole regular starter of similar stature. Critics point to his modest speed as a potential obstacle in Europe’s more physical environment. Nonetheless, his scrappy, relentless approach has drawn comparisons to former U.S. phenoms such as Christian Pulisic and Clint Dempsey.
