Argentina is set to begin its 2026 World Cup campaign against Algeria in a Group J match on Tuesday, according to multiple outlets. The New York Post and CBS Sports both state that Lionel Messi is expected to play for Argentina in the tournament opener against Algeria. Several reports focus on match betting coverage, including odds and predictions from CBS Sports’ SportsLine and expert picks highlighted by Martin Green. Fox Sports also publishes odds and betting-related information for the Group J matchup, framing the game as Argentina’s first match of the tournament against Algeria. While the sources emphasize different elements—such as betting previews, odds, and expert best bets—they align on the core details: the teams involved (Argentina and Algeria), the competition (2026 FIFA World Cup), the grouping (Group J), the timing (Tuesday), and Messi’s expected participation for Argentina. The coverage does not present definitive, identical wagering conclusions across outlets, but it consistently treats the fixture as Argentina’s World Cup debut against Algeria with Messi expected to be available.
