Argentina have played 3-5-2 a lot and it has been fine.
Would need to check but I am sure when played it in past Messi has played behind two strikers and not as one of the front two.
3-5-2 can still be an option but it has to be the right players.
This was a 5-3-2 which they have only played, I think, against Bolivia up in La Paz in that high altitude. Ended in a loss or draw if I recall.
3 CBs, 2 fullbacks, one of which is really a CB. and 1 DM. That was a defensive 5-3-2 without a proper midfield and with no true CF without Higuain. It was a disaster and it showed the first half.
