So we can't predict which country will win in this world cup especially after Saudi Arabia proved it.
We can't predict the exact team that will win the world cup, but we can select at least 5 favorites for the title and be almost sure that the winner is going to emerge from one of them. Argentina is one of those favorite teams, i know they lost to Saudi Arabia, and they are now going to be playing under pressure. If they can get back to their best for their next two games, then they will qualify, and if they cannot, they will be eliminated in the group stage, but even if that happens it does not mean that it then makes it possible for an underdog to win the world cup this year. If one of the favorite is eliminated in the group stage, Argentina for example, there are other favorites like, France, Brazil, England, Spain, Portugal, a winner should still emerge from one of them.
