Those are our preliminary conversations.”Reports suggest that the 55 player list has received an initial cut down to 35, but injuries and niggles have caused further headaches in the selection camp. On Monday, Albiceleste also received a major scare when their talismanic striker Lionel Messi exited his last MLS game of the season with Inter Miami due to muscle fatigue in his left hamstring.While Messi will likely spearhead Scaloni’s roster in a record sixth World Cup appearance, there are also other concerns to be considered.“About 80% of the list is already set. There are others we still have to evaluate, whether because of form or physical condition. We also have to consider that something could happen to someone or that a player could still be doubtful,” Ayala explained.Story continues below this ad“So what do we do then? Do we add a defender or a midfielder? We have to look at the versatility of the players and what they can give you. Whether in some cases we need to play with three or five defenders, and which players can offer you more things,” added Ayala.Argentina FIFA World Cup 2026 scheduleJune 17: Argentina v AlgeriaJune 22: Argentina v AustriaJune 28: Argentina v Jordan
