Lionel Messi has officially concluded his international career with Argentina, describing Tuesday as the saddest moment of his professional life following a 3-0 victory over Benin at Buenos Aires' Monumental Stadium. The 39-year-old superstar marked his farewell with a goal and two assists in what proved to be his final appearance for his country after 21 years of service.

Addressing over 80,000 fans at the iconic venue, Messi expressed deep gratitude for the opportunity to represent Argentina throughout his career. "Wearing this jersey for more than two decades has been an immense honor," he told the emotional crowd. "Through all the difficult moments we faced, both as a team and personally, I never gave up, never stopped showing up."

The veteran forward continued with visible emotion: "Not being able to come back will cause me tremendous pain. I would play forever if I could, because representing Argentina is the greatest privilege an athlete can have."

Argentina manager Lionel Scaloni, who guided Messi to World Cup glory in 2022, paid tribute to the departing legend by stating no player of comparable talent would emerge again. "He stands alone," remarked Scaloni, who shared the field with Messi for a season as teammates. "I have witnessed countless players throughout my career, but none possessed his complete skillset."

Scaloni, who shed tears during the pre-match national anthem, admitted coaching Messi exceeded anything he imagined possible. "My gratitude toward him knows no bounds for everything he contributed," the 48-year-old said. "I told him publicly with whatever strength remained in me: coaching the finest footballer ever was beyond my wildest imagination."

Returning to the Monumental Stadium held special significance for Messi, as Argentina celebrated their 2022 World Cup triumph there with fans. "Standing here on this devastating day, saying farewell to the national team and to all of you," he reflected. "But I will remain supportive from the stands, backing every player who wears this shirt. We stay united always."

Despite the sadness, Messi expressed no second thoughts about his decision's timing. He cited the demanding nature of this year's World Cup campaign, where Argentina fought through to the final before falling to Spain. The emotional journey, including a 2-1 semi-final triumph over England, extracted a heavy toll. Additionally, the death of his father and agent Jorge in August delivered another devastating blow.

"While part of me wants to continue indefinitely, I recognize this is the right moment," Messi explained. "The most recent World Cup pushed me to my limits in every way. We chased the dream of becoming world champions once more, and we came incredibly close. That match against England demanded everything from us physically and emotionally. We fought until we had nothing left, just as we always did wearing these colors."

Scaloni acknowledged Messi leaves behind an extraordinary legacy, though the team must now adapt without their talisman. "Compensating for his absence requires building an exceptional team where every member contributes meaningfully to our collective success."
