Argentina's 2026 World Cup Squad: The Defending Champions Have a Problem — And It Might Be Depth
They won in Qatar. They won the Copa América. Lionel Scaloni's Argentina became the most dominant international side of the 2020s. Then Scaloni left, Lionel Messi turned 38, and the reigning world champions walked into 2026 with a squad that's brilliant at the top and untested in the middle.
Here's who made the cut, what to expect from each of them, and how coach Lionel Scaloni's replacement — Guillermo Barros Schelotto — is likely to line them up.
The Coach: Guillermo Barros Schelotto
Barros Schelotto is not a flashy appointment. He built his reputation across MLS and the Argentine first division, most notably with Boca Juniors and the LA Galaxy. His sides are tactically compact, hard to break down, and dangerous on the counter.
He inherited a squad with a clear hierarchy — Messi, Álvarez, Mac Allister at the top — and has been smart enough not to dismantle it. His expected system is a 4-3-3 that shifts into a 4-2-3-1 when Argentina are out of possession, with De Paul or Paredes dropping to screen the back four.
Goalkeepers
Emiliano Martínez — Aston Villa
The best goalkeeper in the world in tournament football. His penalty shootout record at Qatar 2022 is the reason Argentina lifted the trophy. Now 33, he's still first choice with no argument.
Gerónimo Rulli — Marseille
Experienced backup who has played Champions League football. Solid technically, better with his feet than Martínez. Not a serious challenger for the number one shirt.
Juan Musso — Atlético Madrid
The third-choice keeper who has reinvented himself at Atlético after a difficult spell at Atalanta. His main job in 2026 is to not be needed.
Defenders
Cristian Romero — Tottenham Hotspur
The most aggressive centre-back in the squad. His reading of the game and aerial ability make him the anchor of Argentina's defensive line. Inconsistent in club football, consistently excellent for the national team.
Lisandro Martínez — Manchester United
His Manchester United spell has been injury-riddled, but when fit he's arguably the best ball-playing defender in the squad. Gives Argentina the ability to build from the back under pressure. Fitness is the only question.
Nicolás Otamendi — Benfica
37 years old and still here. Otamendi's physicality has declined but his positioning and leadership experience make him a viable third-choice option. Qatar was probably his best tournament. This one is a farewell.
Leonardo Balerdi — Marseille
One of the most improved defenders in European football over the past two seasons. Strong in the air, comfortable with the ball, and genuinely good enough to challenge for a starting spot.
Nahuel Molina — Atlético Madrid
The best right-back in Argentina's recent history. He scored in the Copa América final. His combination play with Messi on the right flank has become one of the most reliable attacking patterns Barros Schelotto has available.
Nicolás Tagliafico — Lyon
A survivor of the 2021 Copa América and Qatar 2022 squads. Left-back who is technically clean and tactically disciplined. Not flashy, but rarely makes mistakes.
Gonzalo Montiel — River Plate
Scored the penalty that won Qatar 2022. Now back in Argentina after his Sevilla spell wound down. Competition for Molina at right-back.
Facundo Medina — Marseille
One of the younger defensive options in the squad. Physical, aggressive, still developing his composure on the ball. Will likely feature only if injuries hit.
Midfielders
Alexis Mac Allister — Liverpool
The heartbeat of this team. Since his 2022 World Cup breakout, Mac Allister has become one of Liverpool's most important players. His ability to win the ball, drive forward, and pick the right pass in tight spaces is exactly what Argentina need to unlock deep blocks.
Rodrigo De Paul — Inter Miami
His form for the national team has always been stronger than his club numbers suggest. De Paul is the team's engine — he covers ground, tracks runners, and recycles possession relentlessly. Playing alongside Messi at Inter Miami has sharpened him going into the tournament.
Enzo Fernández — Chelsea
The most technically gifted midfielder in the squad. His Chelsea career has been inconsistent, but at international level he controls tempo better than almost anyone. If he peaks in June 2026, Argentina become even harder to stop.
Leandro Paredes — Boca Juniors
The defensive anchor when Barros Schelotto wants a sitting midfielder. His return to Boca has rejuvenated him. Better short passer than De Paul and more disciplined positionally. Likely rotates with Mac Allister depending on the opponent.
Giovani Lo Celso — Real Betis
Probably the most underappreciated player in this squad. Lo Celso has quietly been one of the best midfielders in La Liga. His short passing combinations and movement in tight spaces are elite. Injury history is the only thing keeping him off the team sheet every week.
Exequiel Palacios — Bayer Leverkusen
Two-time Bundesliga winner as part of Leverkusen's historic run. Physical, direct, and effective in transition. Brings a different energy to the midfield than the technicians around him.
Nico Paz — Como
The most exciting young player in the squad. Paz, still only 21, has been extraordinary at Como in Serie A. His dribbling, vision and composure are already at the level of someone five years older. Could break into the starting eleven by the knockout rounds.
Thiago Almada — Atlético Madrid
Almada's MLS career with Atlanta United turned him into one of the most coveted midfielders in South American football, eventually landing him at Atlético. Box-to-box, dynamic, and capable of moments of individual brilliance.
Valentín Barco — Strasbourg
The youngest left-back option, now cutting his teeth in Ligue 1. Explosive going forward but still learning the defensive side of the game. Likely third-choice at left-back behind Tagliafico and Molina.
Forwards
Lionel Messi — Inter Miami
38 years old. The greatest player ever to play the game. At MLS level his statistics remain absurd. Whether he can carry that into a World Cup at altitude and with compact defenses is the central question of Argentina's 2026 campaign. In Qatar he answered it. He almost certainly will again.
Lautaro Martínez — Inter Milan
Led Serie A in goals last season. The most complete centre-forward in Argentine football and the natural partner for Messi's free-roaming game. His hold-up play, aerial ability, and finishing make him the closest thing Argentina have to a guaranteed source of goals when Messi is being crowded out.
Julián Álvarez — Atlético Madrid
The player who made Argentina's 2022 win possible before Messi's final exploded. His work rate, pressing, and goal threat from deep are unique in this squad. At Atlético he has become even more ruthless as a finisher.
Nicolás González — Atlético Madrid
Three attacking players at Atlético Madrid on Argentina's squad — González adds direct speed and the ability to beat defenders one-on-one on the left wing. Reliable from set pieces.
Giuliano Simeone — Atlético Madrid
Diego Simeone's son has earned his place entirely on merit. Quick, aggressive in his pressing, and capable of starting or finishing moves. His best position is wide right, which puts him in direct competition with a fit Messi.
José Manuel López — Palmeiras
The squad's wildcard forward. His Palmeiras form earned him the call-up. Relatively unknown on the world stage but technically sharp and clinical in the box. Watch him in group stage rotation.
Expected Formation: 4-3-3
In practice it plays more like a 4-2-3-1 when defending. Messi roams freely behind the striker line. Álvarez is the pressing engine up front. The double pivot of De Paul and Mac Allister is the engine room.
The Real Question Going Into 2026
Argentina have the best player in the history of football, the best goalkeeper in tournament football, and three genuine world-class forwards. Their weakness, if there is one, is what happens when Messi doesn't turn up and the midfield creativity runs dry.
Enzo Fernández and Mac Allister need to be at their best simultaneously. If either has an off tournament, Argentina become a much more predictable team.
The squad depth at centre-back is also thinner than it looks. Romero, Lisandro Martínez, and Balerdi are the top three — one injury to Romero or Lisandro and the whole defensive structure shifts.
Qatar 2022 was Messi's tournament. North America 2026 could be his last act on the world stage. Barros Schelotto's job is simple: build a team that doesn't need Messi to be perfect every single night, but one that can win it when he is.
Argentina's Group J Schedule: Where and When to Watch
Argentina open their title defence across two American cities — Kansas City and Dallas — with all three fixtures set for prime time or weekend slots in the US.
June 16 — Argentina vs Algeria GEHA Field at Arrowhead Stadium, Kansas City, MO — 9:00 PM ET
The opening match is the one that sets the tone. Algeria qualified through a tough CAF campaign and will pack the midfield. A nervy start is possible. Kansas City's crowd will be loud regardless.
June 22 — Argentina vs Austria AT&T Stadium, Arlington, TX — 1:00 PM ET
The real test of the group. Austria arrive under Ralf Rangnick as one of the most tactically organised sides in Europe. A high press against Argentina's ageing midfield could cause problems. This is the match that determines whether Argentina cruise through as group winners or scrap for second.
June 27 — Argentina vs Jordan AT&T Stadium, Arlington, TX — 10:00 PM ET
If Argentina have already secured qualification, expect rotation. If they haven't, this is where the squad depth gets tested. AT&T Stadium holds over 80,000 — expect a full house for what could be Messi's final World Cup group game.
