Lautaro Martinez scored an extra-time winner as Argentina beat Colombia 1-0 to win a record 16th Copa America title at Hard Rock Stadium on Sunday.

A poor game which had been marred by security and crowd issues, forcing a 82-minute delay, was decided by a quality finish from Martinez -- his fifth goal of the tournament.

The win was the third straight major tournament title for Argentine following their 2021 Copa victory and their triumph in the 2022 World Cup in Qatar.

There were tears before the celebrations though with Argentina captain Lionel Messi going off injured in the 66th minute watching the rest of the game distraught on the bench, while there was an emotional farewell for Angel Di Maria in his final game for the national team.

For Colombia, whose only title came in the 2001 Copa America, it was a disappointing night when little seemed to work for Nestor Lorenzo's team.

There was chaos around entry to the stadium for fans, with organisers blaming supporters for trying to enter without tickets while fans blamed the lack of an efficient entry system to the venue.

The scenes were alarming with some fans needing medical attention for heat exhaustion but after the decision to suddenly throw open the gates, with no checks on those entering, the situation was largely resolved and the game finally went ahead.

Colombia's Jhon Corboba hit the bottom of the post with a speculative shot in the seventh minute but neither side were able to find their flow in the early stages.

Di Maria found Messi in the 20th minute with a low ball into the box and Messi's left-foot shot was saved by Colombia keeper Camilo Vargas.

Colombia had looked the more lively in the opening period and they went close in the 33rd minute when Jefferson Lerma tried his luck from 25 yards out and his low drive forced Emiliano Martinez into a diving save.

- Messi tears -
There was concern for Messi in the 36th minute when he dribbled to the byline but was halted by a sliding challenge from Santiago Arias which was ruled fair left the Argentine captain needing treatment.

Messi, who now plays his club football in Miami, then curled a free-kick in from the left flank but Nicolas Tagliafico's header was just off target.

It had been a disappointing first half and it didn't improve much after the break, when the fans had at least received some entertainment from Colombian singer Shakira.

Argentina failed to deal with a James Rodriguez corner and the ball looped to Davinson Sanchez but he was unable to keep down his header which floated over the bar.

There was finally some of the expected quality when Di Maria produced one of his trademark runs in from the left and forced Vargas into action, the Colombia keeper turning the ball wide of the post.

Then came a major blow for Argentine hopes when Messi went down, without contact, as he ran in midfield, and clearly in pain he went off to be replaced by Nicolas Gonzalez in the 66th minute.

It was too much for Messi, in what may have been his last major tournament, as he sat in tears on the bench, unable to hold back his emotions.

The Argentine fans thought they had grabbed a winner in the 75th minute when Tagliafico found Gonzalez in the box, who beat Vargas with a low drive but the effort was ruled out for offside.

Little changed in extra-time with a half-chance from Miguel Borja after a flick from Jorge Carrascal but the game was settled by a worthy winner.

Leandro Paredes won the ball in midfield for Argentina with a perfectly timed tackle, found Giovani Lo Celso whose first time pass was perfect for the on-running Martinez who confidently fired home the winner.
