Portugal and Morocco are also currently a little more difficult to predict, especially with Morocco's slick performance and being a real dark horse by blowing Spain.
Portugal is still the favorite to win even ever lost versus Spain because they have more experience in high-level events than Morocco. So I think it's not so difficult to predict if Portugal will win at least 2 different goals. But I agree if we compare it with several matches, seem difficult for Portugal can win easily if can't break through the defense and goalkeeper, Because so far their defense is very solid with conceded 1 goal during the event.
although in the round of 16 Portugal was able to win a lot and managed to beat Switzerland with a score of 6-1, it is not a guarantee that they will be able to win a lot when they face Morocco in the quarter-finals later. because Morocco's defense is very solid and their goalkeeper is very promising. Even though many media predict Portugal will win easily against Morocco, I still doubt it, because Morocco has extraordinary cohesiveness, even after defeating Spain, they also simultaneously prostrate themselves.
