Lisandro Martinez arrived at the World Cup carrying more questions than answers. A centre-back who had once considered walking away from football because the pain had become unbearable, he answered in the clearest possible way against Cape Verde: one assist for Lionel Messi, one goal of his own, and a 2-1 win that sent Argentina into the round of 16.
For a defender, that kind of return is rare. For Martinez, it felt like confirmation that the long road back from serious injury had been worth every difficult day.
A Career Path Rebuilt in Manchester
The timeline explains why doubt surrounded him before the tournament. On February 3, 2025, Martinez ruptured the anterior cruciate ligament in his left knee. He spent 292 days away from competitive football, working through rehabilitation with specialists at Manchester United before returning to the pitch.
Even after that comeback, consistency remained elusive. Calf problems and a suspension disrupted his rhythm during the previous Premier League season. By the time Lionel Scaloni named his squad, Martinez was not being discussed as a guaranteed starter. He was being discussed as a player who had to prove he could hold up across a full World Cup campaign.
The final weeks before departure helped his case. Martinez started United's last three Premier League matches, giving Scaloni a live look at his mobility, timing, and confidence. Once selection was confirmed, the 28-year-old from Gualeguay committed fully. For an Argentine who has spent years in Europe, that call carried extra weight.
From Backup Option to Tactical Focal Point
The competition at centre-back shaped the story from the start. Cristian Romero has been the undisputed anchor in Scaloni's back line. The second spot was expected to come down to Martinez and Nicolas Otamendi, the veteran with a medal collection built across more than a decade of international football.
Scaloni's decision against Cape Verde was more aggressive than many anticipated. Rather than defaulting to experience, he dropped Otamendi and started Martinez. The logic was tactical: Argentina wanted more control, and they wanted a left-footed centre-back who could help circulation from the back without forcing awkward adjustments in build-up play.
The move changed the team's attacking rhythm. With Martinez able to play out under pressure, Argentina gained speed and clarity in their passing lanes. That has always been part of his profile. He is not a towering presence in the air, but he reads the game early, steps into space, and finds lines that unlock the midfield.
Against Cape Verde, ranked 69th in the world, that profile translated into production. Argentina, currently third in the FIFA rankings, controlled the tie and advanced with Martinez contributing directly to both goals. In one night, he moved from a rotation candidate to a player Scaloni may struggle to bench.
What Egypt Means for His World Cup Role
The next test arrives quickly. Egypt, ranked 29th and climbing in the latest FIFA update, represent a step up in physical intensity and tactical discipline. Martinez will likely keep his place if Scaloni wants the same left-sided build-up structure that worked against Cape Verde.
There is also a wider squad context. Compared with teammates who arrive with louder headlines, Martinez has often been the quieter name in the group. Yet his offensive contribution in the opening knockout round already exceeded what many expected from a defender. Even Lautaro Martinez, the Inter Milan striker, was outpaced in that category after one World Cup match.
For Lionel Scaloni, that is exactly the kind of flexibility that has defined this Argentina cycle. The coach has never been tied to one fixed XI. He adjusts shape, personnel, and risk level depending on the opponent. Martinez now fits that model not as a compromise, but as a solution.
The Bigger Picture
The arc matters because it is more than one performance. Martinez rebuilt his club career at United, fought through setbacks that could have ended his season, and turned a World Cup selection into a starting role when the stakes were highest. His assist for Lionel Messi and his own finish against Cape Verde were the headline moments, but the underlying story is professional resilience.
Argentina's World Cup path now depends on players who can adapt without losing identity. Martinez has shown he can do that from defence. If he repeats that level against Egypt, the conversation around Scaloni's back line will shift from who might start to who can realistically be left out.
