Di Maria announced in November that the tournament in the United States would mark the last time he represents his country in international football, for which he has earned 144 caps.

The 36-year-old has played a crucial role in La Albiceleste's success in recent years, scoring the winner against Brazil in the 2021 Copa America final, while netting in the 2022 FIFA World Cup final victory over France.

Di Maria, who also scored the only goal against Nigeria in the Beijing 2008 Olympic Games final, continues to demonstrate his importance for Lionel Scaloni's side, playing in four of its five games en route to a sixth Copa final in eight editions.

Messi wants his fellow winger to make one more vital contribution before bringing the curtain down on an illustrious international career.

"Who knows? Maybe he'll score another goal in the final, like he did in all the previous ones he's played in. It would be extraordinary," the eight-time Ballon d'Or winner said in an interview with Direct TV Sports.

"We always tell him that if everything goes well, we have World Cup qualifiers coming up. Nevertheless, 'Fideo' [Di Maria] has made up his mind and there's nothing that can change it."

Should he appear in the final, Di Maria would join Javier Zanetti on 145 caps, behind only Messi, with 186, and Javier Mascherano, with 147, on Argentina's all-time list.

Meanwhile, his tally of 31 goals is only bettered for La Albiceleste by Messi (109), Gabriel Batistuta (56), Sergio Aguero (41), Hernan Crespo (45) and Diego Maradona (34), and he knows he can retire from international duty with his head held high.

"I'm not ready for my last game with the national team, but now it's time," an emotional Di Maria said.

"A thousand things could happen [in the final], but I think that whatever happens, I can leave through the big door. I've done everything to be able to leave through that door.

"I'll take a lot of trophies with me, but the people, team-mates and friends I'll take with me is something you can't buy with anything."
