Immortality awaits!

Immortality has a strange way of finding football finals, and Sunday's meeting between Argentina and Spain at MetLife Stadium offers two very different routes to it.

For Argentina, the story is written in one man's final act.

Lionel Messi, thirty-nine now, arrives at what will almost certainly be his last World Cup match, still level with Kylian Mbappe atop the Golden Boot standings, still the gravitational center of everything his team does.

A win completes the only chapter his career had left to write: back-to-back titles, a second star added to Argentina's crest under his own captaincy, and the final argument settled in any debate about the game's greatest ever.

Lautaro Martinez has done the finishing this tournament, but it is Messi's presence, right down to that stoppage-time assist against England, that has carried Argentina to the brink of history repeating itself.

Spain's version of immortality looks forward rather than back. This is a team without a Messi-sized legend to crown, built instead around Lamine Yamal, eighteen years old and already reshaping what a World Cup winner can look like.

A Spanish victory would be their second star, their first final appearance since that lone triumph in 2010, and proof that the possession-based identity forged by Xavi and Iniesta's generation can survive being handed to teenagers.

Unai Simon's record-breaking run without conceding and Mikel Oyarzabal's quiet reliability up front have carried the collective this far; Sunday asks whether that collective can finish the job a golden generation once did.

One team chases a farewell that erases doubt forever. The other chases a beginning that could define the next decade.

Somewhere under the lights in New Jersey, only one of those stories gets to become the one football remembers.
