the eighth of end there are some party that on paper looks easy for some team like for example Belgian Belgians have more tactical performance and their squad is far superior to the Japanese Belgian should win comfortable.

Brazil: is based on a collective game that for that reason, the game is the most attractive and makes Brazil powerful. Mexico delivers everything on the field that is why they have reached the eighth. But Brazil will win this game as it is the big favorite to take the trophy, as Germany was eliminated in the group stage.

France: the Gauls has a well-structured super team the opposite of Argentina where all its stars are individualistic when facing the arch rival for that reason France should defeat Argentina in the round of 16.

Uruguay: One of the most powerful selections in the group phase with excellent collective game and has with suares and cavani dos de lujo. Portugal depends a lot on ronaldo, which is a disadvantage, since the Uruguayan defense knows how to neutralize an elite player like ronaldo because they have already done so with leonel messi on several occasions.
For this reason Uruguay should beat Portugal and move to the next round.

I am not a forecaster but I have seen all the games of the soccer world cup and I have in mind how each team plays and its weaknesses.
