To be fair Argentina's performance in the Copa America was just pathetic. Even with all those players, they were playing so terribly that you can't even compare it to their WC 2014 form.
Pathetic? I remember them playing great against Paraguay in the group stage, great against Colombia in QF which was 1-0 only be cause Ospina played the match of his life and putting 5 or 6 goals against Paraguay in semis, absolutely thrashing a team that had just beat Brazil. They were huge favourites going into the final against Chile.
