Last month, prior to the draw, Gernot Rohr’s side secured a surprise 4-2 win over the two-time World champions in a friendly held in Krasnodar.
But the former Parma player believes the ‘unpredictable’ nature of the three-time African champions makes it hard to pass a verdict on the last group game - involving both sides - billed for the Saint Petersburg Stadium on June 26.
"The group in which Argentina is not easy, but it is good that it did not get any big national team," Veron was quoted as saying by Dnevno.
"Argentina should go through the finals without a problem, and it is good that the quarter-finals do not cross with big teams. That means we have a few games to clear the shape and become even stronger.
"Nigeria is unpredictable. They always come to us in the group. African players are actually unstable and depend on what they have a day before and how they feel ahead of the game,” he continued.
"Croatia is not bad, it has players in the strong clubs in Europe. Truth, the World have gone through the play, but should not be underestimated. We are stronger than them, but we should be careful.
"Iceland has no experience at these championships, but they have played well in the Euro and through qualifications. We can not label it as a surprise, but as a growing representation.”
