is too early to reach any conclusion

Tunisia exposed the spanish problems there, still a good result for Spain but it was not the same team that we saw versus Ukraine.
So, yes, Argentina is probably the team with the best momentum cause of that crushing victory, but i can't say i'm convinced yet.
When we reach the knockout anything can happen in this World Cup.
And I still have total faith that we'll have a german or italian (although that USA performance made me think twice) victory in the end.
