Fiery 17-year-old MLS star could win MVP over Lionel Messi and bail out Manchester City in 2028

Philadelphia Union's 17-year-old Cav Sullivan has impressed in MLS and is set to join Manchester City in January 2028, though City's Premier League charges may prompt him to reconsider his future.

Philadelphia Union's 17-year-old forward Cav Sullivan has emerged as an MLS talent worthy of MVP consideration, scoring seven goals and recording seven assists in 28 matches this season. The 5ft7in forward from Philadelphia made his MLS debut at just 14 and has broken through in 2026 under interim manager Ryan Richter's backing. "I believe that you are a great player at this level," Richter told ESPN, backing Sullivan's potential.

Sullivan recently made his USMNT debut under Mauricio Pochettino, scoring a history-making first goal for the squad. He is contracted to join Manchester City in January 2028 after turning 18. However, City's recent guilty verdict on Premier League breach charges—with punishment still pending appeal—could prompt Sullivan to reassess his future. Top Premier League clubs, Barcelona and Real Madrid have all been linked with the young star. Former Premier League goalkeeper Brad Friedel suggested Sullivan could be loaned out immediately or pursued by other elite clubs seeking to develop his talent.
