It's true that Croatia is a strong opponent but I think we shouldn't underestimate the strength of Argentina team also .  Except the First match they are unbeatable and their performance was much improved. It sounds like Di Maria is going to be on the field as well, I think if he comes off it will be difficult for Croatia to survive against Argentina's attacking department. I will not underestimate Croatia but I think the attacking and defence department of Argentina is much stronger than Croatia. But nothing can be said confirmly before the match even then I would like to say the percentage of winning ratio of Argentina is more than Croatia.
