Argentina continue their final preparations for their World Cup opener against Algeria in Kansas City, with Lionel Scaloni still keeping everyone guessing. The coach tested both a 4-4-2 and a 3-5-2 formation in training, leaving major questions over the defensive setup. Gonzalo Montiel, Cristian Romero, Nicolas Otamendi, Lisandro Martínez, Facundo Medina, and Nahuel Molina are all in contention for the back line. Further forward, Enzo Fernandez, Alexis Mac Allister, and Rodrigo De Paul look set to anchor midfield, while Lionel Messi and Lautaro Martínez are expected to spearhead the attack as Argentina aim to begin their campaign on the right foot.
