The 2023 Copa Libertadores final will feature a classic Brazil v Argentina matchup as Boca Juniors bid for a record-equalling seventh title while Fluminense, in only their second final, will battle for their first such continental crown.
For the Brazilians, it will be a home tie as the iconic Maracana in Rio will stage the event, on 4 November.
Coach Fernando Diniz, having led his side to the Campeonato Carioca, guided a path past Argentinos Juniors, Olimpia of Paraguay, and fellow Brazilians Internacional to reach this final.
And they could be led to victory by an Argentinian since their striker 35-year-old German Cano is from the opposing country.
He scored the vital goals in their semi-final triumph and is well clear at the head of the competition goalscoring charts.
Fluminense also have two top distributors in the young Andre Trindade and the ageless Felipe Melo.
With home support and a hot front man the odds strongly favour Fluminense continuing the recent dominance of Brazilian clubs.
But perhaps if it did come down to a penalty shootout Boca might well prevail.
After a fairly straightforward group they have, incredibly, managed to negotiate their way through three successive spot-kick deciders.
Against Nacional (Uruguay) they won 4-2, versus fellow Buenos Aires giants Racing it was 4-1, and in the semi-final after two draws they out-nerved Palmeiras 4-2 in Sao Paulo.
Although the very experienced Edinson Cavani missed in that game he did score the goal that took them to the shootout.
Could a 36-year-old Uruguayan outdo a 35-year-old Argentinian?
A substantial part of Buenos Aires (but not all) and beyond, will be hoping he can turn back time and deliver for Boca.
Whatever happens, drama is sure to unfold and history will be made in Rio.
