there is too much talk about Ronaldo lately, he chooses to play in Saudi Arabia, and probably will lose competing skills in some period, afterwards he will have hard time to play against players that are regularly competing in European leagues
who will take captain band in Portugal is a real question, but that will be solved as well, Pepe is probably there until retirement, and there are several good players in team, that can get band on their arm as well
but, overall, Portugal will stay as top European football team for some time certainly, they have good players, and Benfica is also playing great football with several young Portugal players
