If you ask “did Portugal played with the best team”, the answer is no, because mainly of some yellow card players and also to give opportunity to other good players.
if you ask if Portugal played for win, o think they did. But as in many other times, they play in lazy and overconfident way just because they are qualified and are against a weaker team.
I’ve seen this other times before, come to my mind one euro where they lost the third match of the group phase with Switzerland also in a shitty way after winning the first two matches, or the draw against Liechtenstein many years ago.
I hate it when they play like this, they deserve (and deserved today) to loose.
