It wasn’t the result we wanted, but I leave with my head held high, knowing this group gave it their all until the very last second.“I say goodbye with the peace of mind that comes from having left everything on the pitch. “I never held back a drop of effort, never stopped believing, and never stopped feeling that wearing this jersey was the greatest honor of my life.“Thank you to the Argentine fans. Thank you for the unconditional love, for every flag, for every song, and for standing by us during the good times and—above all—during the toughest moments. “You made it so that whenever the anthem played, we felt not like eleven players, but like millions defending the same dream.Otamendi played in all but one of Argentina’s 2026 World Cup matchesAFP“Thank you to my family. You were my refuge during every setback and my strength in every challenge. You endured the distance, the absences, the tears, and the frustrations.

The undoubted highlight of his international career came in Qatar which saw Argentina become world champions for a third time as they beat France in a pulsating encounter in December 2022. Otamendi played every minute of every game for Argentina. As well as World Cup glory, Otamendi tasted Copa America success in both 2021, which was won on Brazilian soil, and in 2024. But Otamendi was unable to help his nation claim back-to-back world titles with the final ending in disgrace for Argentina on account of an unsavoury incident which saw teammate Leandro Paredes throw punches at Spain players immediately after the final whistle. Otamendi is still intent on carrying on his club career; he plies his trade with River Plate having joined them in May on a one-year deal.
