Lionel Messi’s fitness is the biggest story just five days before the 2026 World Cup kicks off. Inter Miami confirmed that the 38-year-old is dealing with muscle fatigue in his left hamstring after being substituted during a match against the Philadelphia Union on May 26. The entire football world is watching — and holding its breath.
Argentina’s coach Lionel Scaloni confirmed the injury, revealing that Messi sustained a muscle strain in his left hamstring during his final Inter Miami match before joining the national team’s training camp.
The good news? Speaking to ESPN, Scaloni said: “Leo is fine. He has trained with the group for some time, which is important. He has not been completely separated from the team and is progressing positively. He might participate in the friendly matches to get some minutes.”
Argentina remain confident he will be fit for their FIFA World Cup opener against Algeria on June 16. That gives the world’s greatest player just over ten days to prove his body is ready for football’s biggest stage.
Context and Background
This is not the first time Messi has battled his body ahead of a major tournament. But this time, the stakes are uniquely high. Already registering two assists in a match that saw a league-record eight goals scored in a half, the 38-year-old continues to show what he can bring to a game — ahead of an attempt to win back-to-back World Cups with Argentina.
Messi is highly unlikely to feature in Argentina’s warm-up matches against Honduras on June 6 and Iceland on June 9. With the captain sidelined for the friendlies, his spot in the attacking rotation could be filled by Atletico Madrid forward Thiago Almada or Como 1907 midfielder Nico Paz.
The medical plan is clear and deliberate. Messi completed individual exercises under the supervision of the national team’s medical and fitness staff, as part of a carefully managed recovery plan designed to ensure he reaches peak fitness before the tournament begins.
Reactions and Impact
Argentina’s Football Association moved quickly to calm nerves worldwide. The AFA released a positive statement: “The players who are suffering from niggles and injuries continue to work with the physiotherapy team on specific exercises on the pitch and are making good progress.”

The Algerian camp — who face Argentina on June 16 — will no doubt be monitoring every update closely. Scaloni told reporters on Friday: “Leo is doing well. Leo trained for a part with the group, which is important. He’s not fully separated — he’s coming along. He may be part of the friendly matches, getting some minutes in these two friendlies.”
The broader World Cup narrative is also at stake. Messi’s presence — or absence — in Argentina’s opener could reshape the entire tournament’s story arc before a single group-stage ball is kicked.
What Comes Next?
All eyes now turn to Monday’s MRI scan, which will give Argentina’s medical team the clearest picture yet of Messi’s recovery timeline. Brazil’s Neymar faces a similar fitness cloud, having been ruled out of warm-up games due to a calf injury and considered doubtful for Brazil’s World Cup opener on June 13. The tournament hasn’t even started — and two of the game’s greatest-ever players are already in a race against time.
For Messi, this World Cup was always going to be his last. Winning it would make him the only player in history to lift the trophy twice as captain. Missing it — or arriving underprepared — is simply unthinkable. The football world will know more by Monday.
