Ngl I didn't even watch the first half, but that was more because I was mad at the 5-3-2 that seemed way too speculative against a team that doesn't know how to defend. Thank god Alejandro went back to the system he'd played most of the time on the second half, which at least made Argentina win in the blow for blow (we could've scored a couple more goals with more precision, but they would've been undeserved). I suppose Gago wasn't 100%, but otherwise we can't win without a playmaker. If anything Biglia should've started, but I guess it's too late for that
Basically the 4-3-3, even if really unbalanced, makes the games more watchable, although of course we can't play like that against France or w/e. At least against a team like that it's understandable—not with that midfield though, Messi is forced to start far from the box without someone to pass the ball.
Congrats to Bosnia for showing that you can play against us without parking the bus, I hope they advance.
