Argentina arrives at the 2026 World Cup as defending champion with a question hovering over Scaloni’s entire cycle: can this team win without the Qatar version of Messi? The short answer is that Argentina is no longer a one-man team. The long answer requires understanding the tactical transformation Scaloni has executed over the past three years.
The system: from a rigid 4-3-3 to an adaptive 4-4-2
At Qatar 2022, Scaloni deployed a classic 4-3-3 with Messi as a free right winger who dropped into midfield. That scheme depended on the Messi-Molina connection on the right flank and on Álvarez’s defensive sacrifice as a high-pressing false 9.
For 2026, the system has evolved toward a 4-4-2 diamond in the defensive phase that transforms into a 4-3-3 or even a 3-2-4-1 in attack, depending on the opponent. The key is the positional versatility of the midfield:
- Enzo Fernández operates as a single pivot or double pivot alongside Alexis Mac Allister, alternating roles according to context. Enzo has consolidated his game-reading at Chelsea, posting notable numbers in ball progressions and passes between the lines in the Premier League (per FBref data).
- Mac Allister has migrated from the Qatar playmaker role to a left interior that allows him to arrive in the box more frequently. At Liverpool, his evolution under Slot has added more verticality to his game.
- The playmaker/enganche position rotates among several candidates, giving Scaloni a flexibility he did not have in 2022.
The Messi dilemma
Messi will be 38 during the tournament. His ability to define an individual match remains intact — he demonstrated this in the South American qualifiers with decisive assists — but his participation in high pressing has decreased noticeably. Scaloni knows this and has prepared a team that can function without him in the first 60-70 minutes of high intensity.
The probable formation with Messi is a 4-3-1-2 where Leo acts as an enganche between the lines, with two mobile forwards (Julián Álvarez and Lautaro Martínez) running for him. Without Messi, the team shifts to a more aggressive 4-3-3 with coordinated high pressing.
Metrics that define this Argentina
| Metric | Observed profile (2024-2026 cycle) | Context |
|---|---|---|
| Pressing | Medium-high, selective | Argentina doesn’t press like Spain, but picks moments to squeeze effectively |
| PPDA (passes allowed per defensive action) | Mid range (~10-12) | Balance between mid-block and high press depending on match phase |
| Progressions | High efficiency in transitions | Enzo Fernández and De Paul as main carriers |
| xG against | Low, notable defensive solidity | Romero-Martínez/Otamendi form one of the most reliable partnerships |
| Possession | 55-60% estimated | Not an extreme possession team, but controls the tempo |

Key players
Enzo Fernández: the new engine
If Qatar was Messi’s tournament, the 2026 World Cup will be Enzo’s. At 25, he has become the most complete midfielder in South America: distributes, recovers, progresses and arrives in the box. His ability to dictate match tempo from the pivot role is what allows Scaloni to alternate between systems without losing structure.
Julián Álvarez: the Swiss Army knife
Álvarez has exploded at Atlético de Madrid under Simeone, which has given him a defensive dimension that was already notable but is now elite. He can play as a 9, as a second striker or as an inside forward. His off-ball work — pressing, covering runs, space runs — makes him the most useful player in the squad.
Cuti Romero: controlled aggression
Cristian Romero is the most aggressive centre-back in the Premier League and brings that intensity to the national team. His anticipations, duels won and ability to play out from the back give Argentina a competitive edge that few teams can match at centre-back.
Weaknesses and risks
- Full-backs in transition. The departure of Molina from the top level and uncertainty about who covers the right flank in defence is the most vulnerable point. Scaloni has tried several options without finding a definitive solution.
- Emotional dependency on Messi. If Messi cannot play due to injury, the psychological impact on the group could be more damaging than the tactical one. Argentina has learned to play without him, but does it want to?
- Minute management. With a 48-team format and up to 7 matches to reach the final, squad depth will be decisive. Argentina has bench quality, but not at the level of France or Spain in certain positions.
Conclusion and outlook
Argentina are favourites, but not through Qatar’s momentum. They are favourites because Scaloni has built a team capable of winning in multiple ways: with controlled possession, in rapid transition, with a low block and counter, or even with direct play to the forwards. That tactical versatility, combined with the experience of winning Copa América 2021, Finalissima 2022, World Cup 2022 and Copa América 2024, generates a competitive resilience that very few teams in history have possessed.
The greatest risk for Argentina is not tactical — it is physical. If the key players arrive fresh for the knockout rounds, this team has everything to repeat. If the wear of the European season and the North American heat take their toll, squad depth will be the difference between glory and early elimination.
