Angle: Messi retirement from international football serves as final warning to MLS: stop treating him as permanent fixture and build sustainable identity survives inevitable departure from sport entirely. We can mention Inter Miami, MLS, Apple TV, Copa America? He retired from international football? In reality Messi hasn't officially retired from Argentina? But background says officially retired. We accept as fictional. Need use raw not copy. We need maybe reference real players/clubs/managers: Lionel Messi, Inter Miami, Javier Mascherano? Tata Martino? Gerardo Martino? Sergio Busquets, Jordi Alba, Luis Suarez, Federico Redondo? Benjamin Cremaschi, Diego Gómez? MLS teams: LAFC, LA Galaxy, Seattle Sounders, Atlanta United, Columbus Crew, Cincinnati, Philadelphia Union, Portland Timbers, New York Red Bulls, NYCFC. Managers: Wilfried Nancy, Pat Noonan, Jim Curtin, Steve Cherundolo, Brian Schmetzer, Ben Olsen? Players: Denis Bouanga, Cucho Hernández, Luciano Acosta, Lucho Acosta, Evander, Riqui Puig, Joseph Paintsil, Gabriel Pec, Marco Reus, Olivier Giroud, Christian Benteke, Hany Mukhtar, Walker Zimmerman, Matt Turner? USMNT: Christian Pulisic, Weston McKennie, Tyler Adams, Gio Reyna, Ricardo Pepi? Argentina: Julián Álvarez, Enzo Fernández, Alexis Mac Allister, Emiliano Martínez, Ángel Di María. Scaloni. Maybe Messi's international retirement means Argentina post-Messi. MLS post-Messi. We can argue MLS got sugar rush, not foundation. Data-backed: attendance records, Apple deal $2.5B over 10 years, Messi's jersey sales, Inter Miami Instagram followers, ticket prices, MLS Season Pass subscriptions? We can mention Inter Miami's Leagues Cup 2023, 2024 Supporters' Shield? In 2024 Inter Miami won Supporters' Shield record 74 points. Messi scored 20 goals in 19 matches? Actually 2024 MLS: 20 goals, 16 assists in 19 matches? Yes. 2025? But we can use. Need avoid exact statistics maybe okay. But editorial can cite. Need be original.
Structure: Para 1 argument: MLS has mistaken Messi's glow for a permanent sun; international retirement is warning. Need first sentence verdict: "MLS has been living on borrowed time, and Lionel Messi's international retirement is the invoice." Good. Then argue. Mention Inter Miami constructed around him, Barcelona reunion, Tata Martino, Busquets, Alba, Suarez. But league-wide identity? No.
Para 2 evidence: What happened when he arrived. Apple deal, attendance, jersey, Leagues Cup. Specific: Inter Miami's 2024 Supporters' Shield, Messi 20g/16a in 19 games, Cucho Hernández, Denis Bouanga, Riqui Puig, Evander, Lucho Acosta were also compelling. Yet MLS marketed Messi as league's face. TV ratings spike for Inter Miami; opposition stadiums sold out. But when he sits, product? Need evidence that league has talent. Maybe cite Columbus Crew's Wilfried Nancy style, LAFC's Bouanga, Cincinnati's Acosta, Portland's Evander. Those are real. The league can survive if it elevates them. But currently schedule, playoff format, roster rules, salary budget, DP rules? The league relies on aging Europeans: Messi, Suárez, Busquets, Alba, Olivier Giroud at LAFC, Marco Reus at LA Galaxy. Need shift to developing and selling young talent:
