I think in particular, not bringing Pastore was absolutely asinine from Jorge. I get why he didn't bring Icardi (Gonzalo, at least on paper, can do everything he can plus more experience) but they really need someone with some quality who can play deeper through the center and that is something Pastore could at least have brought off of the bench.
3-4-1-2 isn't a bad formation considering their squad but for me, Banega and Lo Celso in particular need to start and he needs to just try it with Dybala once just to see if he can take some players off of Messi. I get why he hasn't started him and Messi but you gotta throw some firepower out there. Meza, Lo Celso, Lanzini and Pavon all look promising but I have a feeling their lack of experience is going to catch up with them.
