Seven days after rolling past Iceland 3-0 in their final pre-tournament friendly, Argentina step into competitive mode at Arrowhead Stadium in Kansas City. Lionel Messi and his teammates open their 2026 World Cup campaign as the reigning champions, carrying the weight of a nation that has not stopped celebrating since Qatar. Algeria, meanwhile, arrive in confident form after a 4-0 win over Bolivia last week and a shock 1-0 victory against the Netherlands in June. This is the first competitive meeting between these two nations, and both arrive knowing that the group stage in a 48-team World Cup leaves little room for a costly stumble on opening night.
What’s at stake
With the expanded 2026 World Cup sending 32 teams through from 16 groups of three, the top two from each group advance. That structure makes every point feel heavier in the early rounds, since a loss in game one puts a team in the uncomfortable position of needing results in their final two fixtures to recover. Argentina’s group also features Mexico and South Korea, both of whom are already on three points after the opening round of games. A win here keeps Lionel Scaloni’s side on track for a comfortable passage; a defeat would immediately shift the pressure heading into their second fixture.
For Algeria, the stakes are equally clear. Coach Vladimir Petkovic has built a side with genuine pace and creativity, and a positive result against the reigning champions would be one of the most significant in the Fennec Foxes’ history. Even a draw at Arrowhead would give Algeria a strong platform. A heavy defeat, however, would leave them relying on results elsewhere and likely needing to beat two of their remaining opponents to qualify.
How they got here
Argentina head into the tournament on the back of four wins and one draw from their last five outings. The 3-0 over Iceland, the 2-0 against Honduras, and a 5-0 over Zambia all came in the space of a busy pre-tournament schedule, with only a goalless draw against Qatar in late March interrupting the run. Scaloni has had the luxury of testing his squad without suffering a defeat, and the team looks well-drilled going forward. Algeria’s run is harder to read. They beat Bolivia 4-0 and Guatemala 7-0 in friendly action, but their 1-0 win over the Netherlands in June is the result that will attract the most attention from Argentina’s analysts. A 0-2 loss to Nigeria at the Africa Cup of Nations in January sits as the one blot on an otherwise encouraging preparatory stretch.
Neither side enters this match in a domestic league context, so there is no league table position to reference. What does frame the group picture is the standings after round one: Mexico sit top with three points, South Korea are second also on three, while Czechia and South Africa are both on zero. Argentina and Algeria are yet to play and will slot into those standings after this fixture. Getting off to a winning start would put either side in a strong position ahead of their subsequent games.
Key battle to watch
Alexis Mac Allister and Riyad Mahrez represent the central tactical tension in this match. Mac Allister has become Argentina’s metronome in midfield, controlling tempo and connecting Rodrigo De Paul’s energy with Messi’s movement ahead of him. Mahrez, on the other side, is Algeria’s most dangerous creator and the player Petkovic will want on the ball in tight spaces. How Scaloni’s midfield manages Mahrez’s positioning, whether to press him high or contain him deeper, will likely determine how much space Argentina’s full-backs have to push forward. If Mahrez is neutralized, Algeria’s path to goal becomes significantly narrower.

Our Prediction
Argentina’s pre-tournament form has been impressively consistent and their squad depth far exceeds anything Algeria can match on paper. Scaloni’s side should control the majority of this game through midfield. That said, Algeria have shown they can trouble quality opposition, as the win over the Netherlands demonstrated, and Petkovic will set up to frustrate rather than to open up. Expect Argentina to get the result, but this will not be the walkover the rankings might suggest.
