Need mention Messi retirement international after 3-0 Benin with goal 2 assists. Need parse: Messi retired from international football after scoring and 2 assists vs Benin. This is fictional? Current 2026? Need use facts as raw. Need write body 480-560 words. Need only body. Need ensure title not included. Need no meta. Need 3 paragraphs? They require 3 paragraphs of original analysis: argument, evidence, implication. We can write exactly 3 paragraphs. Need first sentence clear position. Need maybe 500 words. Let's draft around 520.
Need careful: MLS, Inter Miami, Tata Martino? Javier Mascherano? Argentina coach? Lionel Scaloni maybe actual. Benin match? Could mention "against Benin" no details. Need real players clubs managers: Inter Miami, Tata Martino? Current Inter Miami coach Javier Mascherano as of 2025? Hmm 2026? Messi at Inter Miami, coach Javier Mascherano (appointed Nov 2024). MLS commissioner Don Garber. Real players: Luis Suárez, Sergio Busquets, Jordi Alba, Thiago Almada? Atlanta United? MLS. Argentina players: Julián Álvarez, Lautaro Martínez, Enzo Fernández, Alexis Mac Allister, Emiliano Martínez. Need mention Scaloni maybe. Need angle: dual-identity era: Messi was global ambassador for Argentina and MLS simultaneously. Post-Argentina Messi no longer global ambassador for two nations simultaneously; MLS must confront that his international retirement removes Argentina spotlight, forcing league to market club/MLS on own. Need argue MLS has been free-riding on Argentina/Messi dual aura. Need evidence: 3-0 Benin goal+2 assists shows still productive but sunset. Inter Miami's reliance: Suárez, Busquets, Alba aging; Tata Martino? Actually if using Javier Mascherano maybe fine. Need avoid outdated? Let's use "Javier Mascherano" as Inter Miami manager? Might be accurate in 2025/26. But if editorial current 2026, yes. Need mention Don Garber, MLS. Need mention "Apple TV" maybe not necessary. Data-backed: attendance, jersey sales? Need not invent exact stats? Can say "the league's biggest attendance spikes and jersey sales still trace to him" but no numbers. Data-backed maybe "one goal and two assists in a 3-0 win" is data. "34" etc not necessary. Need 480-560 words exactly. Need output only article body. Let's craft.
Paragraph 1: verdict: Messi's international retirement is not just Argentina's farewell; it is MLS's forced adulthood. Argument: MLS spent two years monetizing a dual passport; every Inter Miami broadcast sold as Argentina reunion. The Benin match proves he can still dominate, but the final whistle ends the arrangement: no more Copa America/World Cup narratives to borrow. MLS must now market him as club asset, not global two-nation icon. Need clear first sentence.
Paragraph 2: evidence: Inter Miami construction with Suárez, Busquets, Alba, Mascherano; Tata Martino? Wait Mascherano is coach; avoid Tata if wrong. "Javier Mascherano's Inter Miami" okay. Mention Argentina pipeline: Thiago Almada at Atlanta? Actually Almada moved to Lyon in 2025? Hmm. Real MLS players: Diego Gómez? Not. Use "Lionel Messi, Luis Suárez, Sergio Busquets, Jordi Alba" real. "Don Garber" and "Apple" maybe. Evidence: 3-0 Benin goal+2 assists shows his international engine was still humming; that's exactly why MLS lost leverage. When he played for Argentina, league got global attention by association. Without that, Inter Miami's regular-season matches against Orlando City and Atlanta United must stand on their own
