Lionel Messi will miss Argentina's final Copa America group stage match against Peru due to muscle tightness in his right adductor, sustained during a game against Chile. Despite his absence, Argentina has already secured a spot in the quarterfinals after victories against Canada and Chile. Messi's condition is being monitored daily, with hopes he will return for the knockout rounds. Argentina's head coach Lionel Scaloni will miss the match due to a suspension related to the team's late return to the pitch in previous games. Assistant coach Walter Samuel will lead the team and emphasized that Argentina will still aim to win against Peru. This decision also considers the opportunity to rest Messi and other key players for the more demanding knockout stages ahead.
