Argentina reaches the World Cup final as the reigning champion, and that distinction changes the calculus entirely. A team chasing its first title plays with nothing to lose; a team defending one plays with everything to lose, and Argentina's road included the kind of dramatic comeback that either builds belief or burns through a squad's margin for error.
The complicating factor is goalkeeper Emiliano Martinez, who has admitted to playing through pain in his hand for the entire tournament rather than have a recommended operation. Watch how Spain's attack probes that hand early. If Martinez looks compromised in the opening twenty minutes, Spain's press will only intensify, and Toronto viewers gathering at the Fort York fan festival for the 3:00 PM ET kickoff will get a very different match than the one Argentina's run so far suggests.
