Lionel Messi officially retired from the Argentina national football team on August 31, 2026, closing a 22-year career that began with his debut in 2005 [1, 2]. The 39-year-old forward scored a record 125 goals in 207 international appearances, making him the all-time top scorer for Argentina [3, 2].

Messi led Argentina to victory in the 2022 FIFA World Cup, scoring seven goals including two in the final against France [1, 2]. However, the team fell short in July's 2026 World Cup final, losing to Spain and denying Messi a second world title [1, 4]. Earlier in his career, Messi experienced near misses, including losses in the 2014 World Cup final and the 2015 and 2016 Copa America finals before winning Copa America in 2021 and the 2022 World Cup [1].

His international journey was marked by perseverance and a transformation of the Argentina team under coach Lionel Scaloni, said observers [1]. Messi’s leadership, humility, and love for Argentina earned praise from teammates and peers. Angel Di Maria said, "I only know that I was born in the right century to be able to see you, enjoy you, and on top of that, to share all these years with you on the national team" [3]. Rodrigo De Paul called him "the greatest of all time" and praised the joy Messi brought to fans [3].

Messi’s retirement announcement came in a handwritten letter published on Instagram. He wrote, "It was a decision that hurt – and still hurts deep down – but I understand that the time has come. I swear to you that I always gave it my all... I gave every last drop of myself; I have nothing left to give" [2, 5].

Messi’s father died in August 2026, prompting serious doubts about continuing his football career [3]. Despite retiring from international play, Messi will continue playing for Inter Miami in Major League Soccer, where he has two years remaining on his contract [3, 2].

Public reaction in Argentina on September 1 showed widespread grief and disbelief at losing a unifying national figure beyond football. Damián Tiralongo said, "It’s the end of an era" [4, 5].

Messi’s legacy includes stepping out of Diego Maradona’s shadow and becoming Argentina’s greatest footballer, winning eight Ballon d’Or trophies along the way [1, 2]. His international retirement marks the close of a historic chapter for Argentine soccer.
