I agree with everything you wrote, it really doesn't make sense to keep these players on the bench, Portugal has luck on its side, but that luck won't last forever, Cristiano Ronaldo's crying is almost the player's last act in major tournaments. Despite being a legendary player, the weight of age is starting to show, he could be a second-half player, or change position... it will be very difficult for Portugal to survive any longer in this competition.
Oblak made a lot of saves in this match, otherwise Portugal would have won in regulation time. It was not Ronaldo's day, he was a lot greedy with free kicks, he should have shared with Fernandes, if you see that you are not doing well, then share with others, it was a little selfish on Ronaldo's part, but he behaved like a leader and this is his decision with whom none of the players argued. And of course it is worth noting Costa, who showed a phenomenal flair in the penalty shootout.
