This was not the potential Copa America farewell that Lionel Messi had dreamed of.

With a little over an hour played in Miami, where he is tearing through MLS sides on a weekly basis, the eight-time Ballon d'Or winner was in tears as he trudged off with an apparent ankle injury.

The next Copa America is not until 2028; Messi will be beyond 40 - surely, this was his last appearance in the competition in which he has now played more games than any other player?

For Messi's individual pain, though, there was national glory. Unlike Cristiano Ronaldo at Euro 2024, with Portugal crashing out in the quarters, Argentina have gone the distance and, for a third successive major tournament, come out as the top dogs. They beat Colombia 1-0 on Sunday and claimed a record-setting 16th Copa America title.

But if the 2021 Copa America and 2022 World Cup were all about their magical number 10, this time around, Lautaro Martinez provided the spark.

Martinez has not been a regular starter under Lionel Scaloni. He endured a difficult World Cup in Qatar on a personal level, failing to score from 14 shots and an accumulated xG of 1.81.

Yet in the United States, on the back of a fantastic season with Inter, Martinez has shown there is life after Messi for Argentina.

Despite having already scored four goals at the tournament to lead the Golden Boot race ahead of kick-off against Colombia, which was delayed by over an hour due to crowd trouble outside the Hard Rock Stadium, Martinez was not called upon until seven minutes into extra time.

It had, to that point, been an attritional encounter. Sure, plenty of shots (14 for Colombia, seven for Argentina) but Nicolas Gonzalez's disallowed goal and a strike off the post from Jhon Cordoba were the closest either team came. The second half alone, meanwhile, featured 13 fouls as the darker side of South American football reared its head.

This was not a game for flair. James Rodriguez, the Player of the Tournament, still got on the ball for Colombia when he could - he created three chances and played a match-leading 20 passes into the final third. Angel Di Maria, in his final match before international retirement, provided some spark for Argentina with three key passes of his own.

But it was Martinez who would make himself the (unlikely) hero. Five minutes after his introduction, he was put through by fellow substitute Giovani Lo Celso and, with his only shot of the night, coolly put Argentina ahead.

Jubilation for Argentina, who continued the pattern that began in 1983, which consists of alternating two-time champions and new winners at the Copa America. 

Deflation, though, for Colombia, whose long unbeaten streak came to an end after 27 games, and their 23-year wait for a second Copa America title will roll on to become 27 years, at least. Will they get a better chance, especially after seeing Messi go off?

Argentina had less possession than their opponents for the first time since the semi-finals against Croatia in the last World Cup, with Colombia seeing 55.7% of the ball.

But even if Messi, who scored only once across the tournament, was not at his fluid best, or even available at all, Argentina proved they can win without him. After he dragged them to glory in Qatar, Messi had to watch on - with his ankle swelling - from the sidelines as Martinez got Argentina over the line.

This victory is one that has been built on a spectacularly solid defence, too. Argentina conceded only once in six games, in the quarter-final against Ecuador, which they won on penalties. Among the teams that played at least five matches in any edition of the Copa America, only four conceded fewer than two goals: Argentina in 2024 (one), Colombia in 2001 (0), Brazil in 1989 (one) and 2019 (one).

And what of Messi, then? 

At 37 years and 20 days old, he became the oldest player to start a Copa America final in the 21st century. He is also the first player to play in five finals (2007, 2015, 2016, 2021 and 2024), surpassing Javier Mascherano (2004, 2007, 2015 and 2016).

He had not been substituted in a Copa America match since July 2007, also in a meeting with Colombia, but needs must.

If this was, as expected, his farewell appearance in the competition, he goes out a two-time champion and with 14 goals to his name, three short of the tournament's record scorers.

Martinez, meanwhile, has completed his redemption arc. His tally of five goals not only wins him the Golden Boot, but also matches the best effort by an Argentine at the Copa America since the turn of the century (along with Messi in 2016 and Juan Roman Riquelme in 2007).

His goals came from just 221 minutes of action, and he started just two of Argentina's six matches.

Colombia will lick their wounds, but so too must CONMEBOL and CONCACAF. 

Passions run high in South American football, and the Americas in general, but the United States will be hosting a World Cup in two years' time. The chaos outside the stadium gates, which resulted in hundreds if not thousands of fans entering without tickets, and the match being delayed, does not reflect well at all.

Like Martinez in an international shirt, those governing bodies must up their games.
