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.
