Scaloni's Late Defensive Shake-Up: Senesi Replaces Injured Balerdi

Lionel Scaloni’s World Cup blueprint took a heavy hit before a ball had even been kicked.

Defender Leonardo Balerdi suffered a severe muscle tear in the soleus of his right leg during training, an injury serious enough to rule him out of the tournament and force Argentina into an unwanted reshuffle at the back. What should have been a routine preparation camp suddenly turned into a scramble for solutions.

The Argentina national team confirmed the diagnosis and the brutal consequence in a stark statement across social media and in front of the cameras: Balerdi “will not be able to be part of the squad that will play in the World Cup.” For a player on the cusp of a major international breakthrough, the timing could hardly be crueller.

Scaloni did not rush to fill the gap. He held off on naming a replacement until after a pre-tournament friendly against Iceland, using the game as a live laboratory to test his defensive structure and weigh up his options.

“Today’s test left me satisfied and cleared up many doubts regarding what the team might be lacking... Maybe I’ll take one or two more days to announce Balerdi’s replacement,” he said, outlining a deliberate, meticulous approach rather than a knee-jerk call.

The pressure finally told on the decision-making process once the Iceland match was in the books. Marcos Senesi, who had been on standby, got the call. He will now travel to the camp in Kansas City to join a back line already loaded with experience and talent.

Inside the camp, the mood was mixed: deep disappointment for Balerdi, respect for his misfortune, but also a quiet confidence in the method behind choosing his successor. The coaching staff stressed how carefully they had handled the transition, keen to maintain stability in a defensive unit that underpins Argentina’s ambitions.

For Senesi, the past 24 hours have been transformative. At 29, with only three international caps, he has spent much of his career on the fringes of the Albiceleste. Now he walks into a World Cup squad.

The former Bournemouth defender, who once turned down a call-up from Italy, had already secured a significant move in his club career, agreeing a free transfer to Tottenham starting July 1. That alone would have made this summer a landmark moment.

Now he heads to a World Cup camp where he will link up with future Spurs team-mate Cristian Romero, reuniting in an Argentina defence that first blooded him back in 2022 against Estonia. From standby list to World Cup stage, from contractual limbo to Premier League move, Senesi’s trajectory has shifted in an instant.

For Scaloni, the plan has changed. For Senesi, the opportunity of a lifetime has just arrived.
