Javier Mascherano silenced doubters by leading Inter Miami to their first MLS Cup title in December 2025, just one year after taking over as manager. The 41-year-old Argentine had no prior senior managerial experience when hired in November 2024, having only coached Argentina's youth teams. His appointment raised eyebrows after Gerardo Martino's departure, given Martino's decorated resume including Barcelona and an MLS Cup with Atlanta United.

Mascherano's early tenure was rocky, with Inter Miami exiting the Concacaf Champions Cup semifinals and posting a pedestrian 6-5-3 MLS record. Between April 27 and May 24, the Herons won just one of eight games, conceding 23 goals. Despite this, the front office and players remained steadfast in their support. Mascherano emphasized authenticity and player-first communication, building trust through transparent messaging and relating to his squad from his playing days.

The team's evolution peaked in the postseason when Mascherano made the gutsy decision to bench Luis Suárez after his suspension in the first round. Miami won four straight games without their star striker, including commanding victories over FC Cincinnati and New York City FC. Co-owner Jorge Mas praised Mascherano's tactical growth and difficult selection decisions, noting the team's level of play in the final three matches was unprecedented in club history. Mascherano proved his critics wrong, becoming the first coach to deliver silverware to Inter Miami.
