Argentina has been the biggest surprise so far. I though they'd be one of the favorites, but their game has been awful. Hard to tell what they're even trying to do, no-one in midfiled to build-up play unless Messi drops deep and then there's glaring holes in the attack. They couldn't move the ball to stretch Mexico's defence until a moment of magic by the maestro. Hope they'll improve soon.
Felt to me like Julian Alvarez should be starting alongside Lautaro Martinez in attack, and drop Messi to midfield. But even then it's not gonna work out if no one else in midfield wants to drop deeper to receive a pass from the defenders.
