Angel Di Maria came up with the vital goal, but nobody did more to drive the Albiceleste to glory than their veteran captain
Finally, the day arrived, and in the most thrilling of circumstances.
Lionel Messi finally banished the memories of years of international despair as his Argentina team downed Brazil 1-0 to take the Copa America title in the Selecao's own backyard.
And having played every single minute of the tournament, driving his bruised body to new limits amid the flying tackles of South America's fearsome defenders, there is now no doubt that this Copa, from start to finish, belonged to the 34-year-old wizard - who was just seven when, in 1993, the Albiceleste last experienced glory in this competition.
The Barcelona star, moreover, had yet to test his wits against a team of the calibre of the Selecao, who had breezed through the tournament on home soil to set up this much-anticipated decider.
Anyone tuning in expecting a festival of flowing football between these two titans, though, was soon to be disappointed. Argentina and Brazil went toe-to-toe in a brutal first half, with play barely developing amid a torrent of fouls from both sides.
It took one spectacular move from the visitors, an oasis in this football desert, to break the deadlock. Rodrigo De Paul let loose with a perfectly weighted lofted pass from inside his own half which just eluded Renan Lodi, amongst the Selecao's weakest links, to release surprise starting inclusion Angel Di Maria.
The Paris Saint-Germain star has featured more from the bench in this Copa, but he was ideally placed to take advantage of the sole clear chance of the first half, chipping over the onrushing Ederson and sending the handful of Argentina fans lucky enough to gain access to the final into ecstasy.
One of the first to congratulate him was Messi, who had few chances to make his mark amid the constant attention of yellow shirts but still posed a constant potential danger every time he touched the ball.
He and the entire Argentina team then breathed a collective sigh of relief minutes later when Di Maria, chasing an almost identical ball, appeared to injure his ankle after treading awkwardly on the Maracana turf. Thankfully for a man who has suffered so many injury woes in international colours, it proved a momentary scare.
Proof, perhaps, that the Albiceleste's final fortunes were finally turning?
Despite going behind, Brazil coach Tite altered his rigid scheme, freeing up Neymar with the arrival of Roberto Firmino and pushing slightly more forward. The threat from the reigning champions in turn grew: six minutes into the second period Richarlison thought he had levelled with an opportunistic rebound finish, only to see play brought back for offside.
Seconds later, Argentina's penalty hero Emiliano Martinez came to the rescue, stopping from the Everton forward who had begun to revel in the space behind left-back Marcos Acuna. The Albiceleste defence, erratic at the best of times, creaked and croaked, but just managed to stay in one piece, to the frustration of the expectant hosts.
