Argentina are the reigning world champions heading into FIFA World Cup 2026, and Lionel Messi — who lifted the trophy in Qatar — is widely expected to be part of their squad for what would be his sixth and almost certainly final World Cup. At 38 years old during the tournament, Messi's fitness and participation remain unconfirmed but are the most-watched storyline in global football.

Why Messi's sixth World Cup matters more than any other
For most footballers, making a sixth World Cup would be the stuff of fantasy. For Lionel Messi, it is — as of the time of writing — a realistic, if far from certain, possibility. He enters this conversation not as a sentimental late-career passenger, but as the man who delivered Argentina's first World Cup since 1986, with a performance in Qatar 2022 widely regarded as the greatest individual tournament in the competition's history.
The arithmetic of history
Messi debuted at the 2006 FIFA World Cup in Germany as a teenager, and has appeared at every edition since. A sixth appearance in 2026 would equal the record held by players such as Lothar Matthäus and, in the women's game, Formiga of Brazil. In men's football, six World Cups is the absolute ceiling — and Messi is knocking on it.
What Qatar 2022 established
His performance in Qatar — seven goals, three assists, Golden Ball award — rewrote the conversation around his legacy. Arriving at 2026 as the tournament's defending champion and greatest-ever performer changes the emotional and tactical calculus for everyone involved, Argentina included.

Messi at Inter Miami: The fitness question that defines everything
The most pressing question surrounding Messi's potential sixth World Cup appearance is not his quality. It is his body.
MLS, workload and age
Since joining Inter Miami CF in July 2023, Messi has navigated a series of injury interruptions. His ability to stay fit across a full MLS season — and to peak physically during a summer World Cup — is the variable every Argentina supporter monitors above all else. ESPN's soccer coverage has tracked his club appearances closely, and the pattern suggests a player managing his minutes with care.
What "fit Messi" still looks like
When healthy and motivated, Messi at Inter Miami remains a generational talent. His passing range, vision and dead-ball delivery are, if anything, better preserved than his explosive pace — which has naturally diminished. At a World Cup, where Argentina's system is built around his intelligence rather than his sprint, that matters less than it might elsewhere.
"The World Cup is the one competition that changes everything for Messi — it always has. You can't separate him from it." — common analytical refrain from football observers tracking his career arc.

Argentina as defending champions: The holder's burden
Defending a World Cup title is notoriously difficult. Only Brazil (1958 and 1962) and Italy (1934 and 1938) have successfully done so. The historical odds are stark.
The expanded tournament and its implications
The 2026 edition is the first to feature 48 teams across 12 groups, meaning the road to the final is longer than ever — 104 total matches, more rounds, more exposure to fatigue and upset. For an Argentina squad built around ageing key players, the expanded format is both opportunity and risk.
Argentina's squad transition
The core of Argentina's Qatar 2022 squad — Messi, Ángel Di María (who has retired from international football), Sergio Agüero (long retired), and others — has changed. A new generation of players has been emerging through the domestic and European club system, but the backbone of the side remains recognisable. For the definitive, up-to-date picture of who is in and who is out, the [full World Cup 2026 squad tracker at Footballens](/guides/world-cup-2026-squads-tracker) keeps every confirmed list updated as AFA selections are announced.
The manager question
Lionel Scaloni remains in charge of Argentina at the time of writing, having delivered the Copa América 2021, the Finalissima 2022, the World Cup 2022 and the Copa América 2024. His record is unmatched in recent Argentine history. Whether his tactical structures evolve to accommodate an older Messi — or whether they simply continue to revolve around him — is one of the defining questions of the 2026 cycle.

How Argentina might set up at World Cup 2026
This section deals in analysis and projection, not confirmed selection. All formations and personnel references are speculative based on current trends.
The Scaloni system
Under Scaloni, Argentina have typically operated with a back four, a hardworking midfield trio, and a front three or attacking midfield unit shaped heavily around Messi's movement. The system is flexible — it bends to what Messi does — and that flexibility has been a tactical strength.
Key positions to watch
- Goalkeeper: Emiliano Martínez (Aston Villa) remains the established first choice and one of the best in the world in his position.
- Defence: Romero, Otamendi and others from the Qatar core are approaching the end of their international careers; younger options are emerging.
- Midfield: Rodrigo De Paul, Enzo Fernández and Alexis Mac Allister formed a formidable base in Qatar and at Copa América 2024. All are younger and likely to remain central.
- Attack: Julian Álvarez's development at his club level will be central to how much pressure is taken off Messi to create and score.
| Position | Established player (unconfirmed for 2026) | Age at tournament |
|---|---|---|
| Goalkeeper | Emiliano Martínez | 33 |
| Centre-back | Cristian Romero | 28 |
| Midfielder | Enzo Fernández | 25 |
| Midfielder | Alexis Mac Allister | 27 |
| Midfielder | Rodrigo De Paul | 32 |
| Forward / CAM | Lionel Messi | 38/39 |
| Forward | Julián Álvarez | 26 |
Note: Ages calculated at time of tournament (June–July 2026). Squad selection unconfirmed.

The Ronaldo parallel: Two legends, one final stage
Messi's potential sixth World Cup is impossible to discuss without reference to [Cristiano Ronaldo](/guides/ronaldo-portugal-world-cup-2026), who is also targeting a sixth appearance at the same tournament at the age of 41. The two men have defined an era of football together, and 2026 threatens — or promises — to be their shared final act on the sport's biggest stage.
Same tournament, different stories
Where Messi arrives as a champion with nothing left to prove, Ronaldo arrives still chasing the one major trophy that has eluded him. Portugal have not won a World Cup. For Ronaldo, [Portugal's World Cup 2026 campaign](/guides/ronaldo-portugal-world-cup-2026) carries the weight of unfinished business.
How the numbers compare
| Metric | Messi | Ronaldo |
|---|---|---|
| World Cups entered (to 2022) | 5 | 5 |
| World Cup goals (to 2022) | 13 | 8 |
| Best World Cup finish | Winner (2022) | 4th place (2006) |
| Age at 2026 tournament | 38/39 | 41 |
| Current club | Inter Miami CF | Al-Nassr |
| 2022 individual award | Golden Ball | — |
Both men playing at a sixth World Cup would be one of sport's great narrative moments. Whether both are fit and selected remains unconfirmed — but the possibility alone has elevated anticipation for the entire tournament. The BBC Sport football section and The Guardian's football coverage have both dedicated significant column inches to the question.

Argentina's route: Group stage, potential opponents and the path to the final
The 2026 World Cup group draw had not been finalised at the time of writing. What is known is the structural framework.
The format in brief
- 48 teams divided into 12 groups of 4
- Top two from each group, plus the 8 best third-place teams, advance to a 32-team round of 16
- Standard knockout rounds follow: quarter-finals, semi-finals, final
- The final is scheduled for 19 July 2026
Potential challenges for Argentina
As holders, Argentina will be among the seeded teams at the draw. Their likely path through the knockout rounds could include any of the traditional South American, European or African powerhouses. Brazil, France, England, Germany, Spain — all represent plausible and formidable knockout opponents. CONMEBOL's collective strength in 2026, with six qualified South American nations, means the continent will be well-represented deep into the competition.
- Argentina have won the World Cup three times (1978, 1986, 2022)
- They are one of only eight nations ever to have won the tournament
- Defending champions have been eliminated at the group stage four times since 1966
- The expanded CONMEBOL qualification process produced its full complement of qualifiers for the first time under the 48-team format

What Messi winning or not winning would mean for his legacy
This is, ultimately, a question about narrative rather than data. And it is worth addressing directly.
He has already won everything
The honest answer is that Messi's legacy is secure regardless of what happens in 2026. The debate about Messi versus other all-time greats — a debate that ran for years partly on the argument that he hadn't won a World Cup — was settled in Qatar. UEFA's coverage of global football and every major publication have revised their assessments accordingly.
But football doesn't work on logic
Football supporters and the media do not operate purely on settled verdicts. If Argentina win in 2026 with Messi playing a meaningful role — even a reduced one — the resonance will be enormous. If they exit early or if Messi is injured and absent, the story becomes one of a great player's final chapter shaped by circumstance rather than triumph.
The sixth World Cup as cultural moment
There is also a broader cultural dimension here. Messi at a sixth World Cup, on North American soil, in cities like New York/New Jersey, Los Angeles, Miami and Dallas — markets where Inter Miami has helped grow his commercial and cultural footprint significantly — represents something beyond football results. The global reach of the FIFA World Cup means that this storyline will be followed by audiences who don't normally watch club football at all.

Frequently asked questions
Will Messi play at the 2026 World Cup?
Messi has not officially confirmed or denied his participation in World Cup 2026 as of the time of writing. He will be 38 years old during the tournament. Most credible sources consider his participation likely but dependent on his fitness at Inter Miami through the 2025–26 MLS season. No official AFA squad announcement has been made.
How old will Messi be at the 2026 World Cup?
Messi was born on 24 June 1987, meaning he will turn 39 during the tournament itself — specifically during the group stage, should Argentina qualify beyond early rounds. He will be 38 at the start of the competition when it opens on 11 June 2026.
Would 2026 be Messi's last World Cup?
