I can't believe Portugal was struggle to beat Slovenia, moreover Ronaldo failed to score the penalty kick. Diogo Costa is really a man of the match, he saved 3 penalty shots, that's crazy. This is why FC Porto is very known as one of the best defensive teams.
Today two match would be unpredictable, any team will have a chance to win, not to mention they might ends in draw.
Personally I think Netherlands will win, and Austria vs Turkey will ends in draw, but Austria will qualify to the quarter final.
Today we will see whether Austria will show the same form as in the group stage and whether it's a real candidate for the final, on the weaker side of the ladder. After the group stage, for me they are the 3rd team to win: Germany, Spain and Asutria.
