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.
I disagree with you, it's France will have like 90% chance of winning if they drag this to PK.
Maybe Portugal made a perfect round versus Poland but, even if I support Poland, France have better players for the PK (and certainly the best for that in this Euro 2016).
