So many wrong choices. It's clear that Argentina is bereft of any creativity in midfield and depends solely on Messi to create. You could combat that by playing Di Maria in the midfield trio, putting Lo Celso in there and playing Dybala as the #10.

To make matters worse goes for Tagliafico over Rojo and starts Meza again. Doesn't realize Biglia is a better choice than the corpse of Mascherano as the holding midfielder, either.
