Argentina 3-0 Algeria: Messi Hat-Trick Sends Holders Top of Group J
Argentina opened Group J the way champions are expected to open it. Lionel Messi scored a hat-trick in a 3-0 win over Algeria, and the holders ended the first round top of the section after Austria's later win over Jordan left the group with an early two-team split.
Argentina vs Algeria final score
Final score: Argentina 3, Algeria 0. Messi scored in the 39th, 65th and 88th minutes to turn an initially awkward opener into a clear result.
The Guardian's live report described Algeria as competitive for long stretches before the second goal broke the match open. That matters because the final margin was decisive even though the game did not begin as a procession.
With the hat-trick, Argentina gained the strongest possible opening position short of also seeing Austria slip up in the other group match.
How Group J changed
Group J now has Argentina first on three points with a +3 goal difference and Austria second on three points with +2 after beating Jordan 3-1.
Jordan are third on zero points with a -2 goal difference, and Algeria are fourth on zero with -3. That means Algeria not only lost the head-to-head points battle with a favorite, but also absorbed goal-difference damage immediately.
The table therefore already points toward a two-team race for first place unless Jordan or Algeria can change the story on the second matchday.
Qualification picture
Argentina's next match against Austria is now the key to the group. Win it and the holders would take a major step toward automatic qualification for the round of 32; draw it and they would still keep the inside track.
Algeria remain alive because third place can still qualify in the 2026 format, but their next match against Jordan now carries obvious pressure. Another defeat would leave them needing a rescue on the final day and help elsewhere.
From Argentina's side, the cleaner benefit is control. Opening with both points and goal difference means they can enter the Austria game from a position of leverage rather than recovery.
Key players and talking points
Messi is the headline because a World Cup opening hat-trick instantly changes the tone of both the group and the Golden Boot race. Argentina did not need many names in the spotlight once he took over the match.
The broader football takeaway is that Argentina were patient. They did not force the game before halftime, but once the lead arrived they looked increasingly comfortable attacking the spaces Algeria had to leave.
No reliable post-match injury update was confirmed across the sources reviewed, so this report does not treat fitness concerns as established facts. The verified story is the hat-trick, the clean sheet and Argentina's hold on first place.
