Former USMNT goalkeeper Kasey Keller has voiced concerns regarding Major League Soccer's long-term strategy once Lionel Messi retires. Keller acknowledges Messi's significant impact since joining Inter Miami in 2023, which brought unprecedented global attention to the league. However, he emphasizes that MLS cannot perpetually depend on a single superstar. Keller, drawing parallels to figures like George Best at Manchester United and Thierry Henry at Arsenal, asserts that clubs and their supporters must remain the primary focus, not individual players. With Messi, now 39, expected to retire within a couple of years, Keller stresses the impossibility of replacing such a figure. He also advocates for loosening financial restrictions within the Designated Player rule, allowing clubs greater autonomy in spending to build competitive teams. Inter Miami co-owner David Beckham, meanwhile, continues to back Messi for another Ballon d'Or.
