Santos has found the best formula for his squad, despite not playing one of the best player for 70 minutes against Switzerland and 50 minutes against Morocco. I don't think Santos underestimates the quality of the opposing team, but Santos doesn't want his game to be centered on Ronaldo, who might be more dangerous for his team.
Many people say Portugal's game is better without Ronaldo, but not a few of them are denied by fans. Small mistakes will become big when the team loses, but if Portugal win against Morocco then surely Santos will be praised. The World Cup is over, and now what else.
Seriously? If Portugal's game was so much better without Ronaldo, then they would have won against a weak team such as Morocco. Game will be centered around Ronaldo when he plays, because the opposition realizes that he is the player who is most likely to score goals. And this gives opportunities to the other Portuguese players to make attempts on their own. What next? Brazil playing without Neymar and Argentina playing without Messi, so that the game doesn't get centered around these players? In international football things doesn't work like that.
