Argentina defender Nicolas Otamendi has described Lionel Messi as a "competitive animal" whose relentless drive continues to inspire the reigning world champions as they prepare to begin their FIFA World Cup title defence against Algeria.
Messi, 38, is set to make history by appearing at a record sixth World Cup, with anticipation building around what could be the legendary captain's final appearance on football's biggest stage.
Veteran centre-back Otamendi, who will feature in his fourth World Cup and has shared much of Messi's international journey, said the forward's winning mentality remains as strong as ever.
"He's a competitive animal," Otamendi said. "He makes you keep trying, he doesn't let you relax."
The former Manchester City defender also praised Messi's character away from the spotlight, highlighting the humility that has endeared him to teammates throughout Argentina's successful era.
"We enjoy every moment with him," Otamendi added. "He is a humble person who enjoys the team gatherings and training sessions."
Despite concerns over Messi's fitness after he experienced muscle fatigue during Inter Miami's victory over Philadelphia last month, the Argentine captain has eased fears by returning to action with an impressive cameo appearance in a warm-up match.
Messi remains the focal point of Lionel Scaloni's side as Argentina seek to retain the trophy they won in Qatar four years ago. His influence extends beyond his performances on the pitch, with teammates continuing to draw motivation from his professionalism and determination.
Otamendi's comments underline the immense respect Messi commands within the squad, with the veteran defender insisting the eight-time Ballon d'Or winner's competitive edge continues to set the standard for the entire team.
As Argentina prepare to face Algeria in their Group J opener, Messi once again carries the hopes of a nation dreaming of back-to-back World Cup triumphs, backed by teammates who believe their captain's hunger for success remains undiminished.
