The shape of this squad points to stability.
That continuity is not sentimental. It is tactical. Argentina still look most comfortable when they control the centre of the pitch, slow the game on their terms and then accelerate once space appears.
If Argentina are to go deep again, the tournament will likely be decided by the authority of Enzo Fernandez, Alexis Mac Allister and Rodrigo De Paul. That trio brings control, work rate and passing range, and it remains the clearest reason Scaloni can keep faith with an established system.
There are fresh options around them. Nicolas Paz and Valentin Barco appear to offer added dynamism, while Jose Manuel Lopez gives another route in attack. But the broader message is clear: evolution, not reset.
The biggest question is fitness. Reports suggest Messi arrived with a physical complaint, while Martinez and Romero are also managing issues before the opener against Algeria on 17 June. None of that guarantees absence, but it does sharpen the focus on squad depth earlier than expected.
That is the tension around this defence: Argentina still have the structure of champions, but the first storyline may be about availability rather than style. After Algeria, the tests against Austria and Jordan should reveal whether continuity is enough - or whether this squad needs its newer pieces sooner than planned.
