martino is about right on the interview after the game that both sides were there to neutralize the other.
but, what would be his plan for this game? prepared for penalty shootout? if not what he supposed to do to kill the game beforehand? i don't think he had one.
just take a look of the players with the current argentina squad:
messi, aquero, pastore, higuain, tevez, diMaria, mascherano, otamendi, rojo, zabaleta...etc
all are top tier players and there are some more sublime players very close to the level if not par. this is a very very strong national squad even you count it in all times history. if they don't deliver anything substantial this is really a big waste
martino may not be the problem of non-performing. but certainly he is no solution however
