Well that's your own take on the game as everyone has their own opinion and for me I think this game is definitely going to end in a draw and maybe they will settle the winner through a penalty shoot out and I don't say this for just this game as I feel that would be the era of the actual ending for most of the games of round of 16 in this competition.
I don't think there will be extra time for the France vs Belgium match. Indeed, that is a consequence when both of them draw in normal time, but considering that France has many quality players, what I believe is that they can win the match in 90 minutes. Of course you can make choices that you think have a high probability such as a draw in normal times, but I'm not sure that will be true.
Switzerland vs Italy and Germany vs Denmark should also be tough matches. Switzerland seems to have a good mentality to win the match against Italy, but I know that Italy is very difficult to beat. I tend to consider this match as a draw in normal time, but not so with Germany vs Denmark. Germany is my favorite, but nothing is certain.
