Portugal still have a chance to win if the match go to extra time, in penalty kick every side have a chance 50/50 maybe portugal would playing defensive at final match.
If they drag this to PK, Portugal will have like 90% chance of winning. They made a perfect round against Poland and they can do it again.
It's hard for Portugal to win in this match, you can see france against germany
and wales. france always win with more than 1 goals. My prediction the score this match 3-1 or 3-0
