your attempt to give a result is valuable, but for me the results are not that precise. Also, I think that Uruguay will win 2-1 or 3-2, minimum 2 goals will be on that game in my opinion.
Brazil and belgium are two very offensive selections, that´s why I think that Brazil will win but the match will end with more than 2 goals. In the case of Sweden and England I believe that they can stay 0-0 till the penalties. Finally Rusia vs Croacia, Rusia had an unexpected result in the round of 16, but I think that this match will be the end of luck for Rusia, framing Croatia as a clear favorite to win, I wouldn´t be surprised if Rusia receives 3 goals and doesn´t score any. I uploaded an analysis of Uruguay-France, and in a couple of hours I will publicate the Brazil-Belgium analysis too if you´re interested.
