Apart from that, it looks like Ronaldo will be resting if see the level of difficulty of opponents Portugal will face in the coming days. But I'm sure Ronaldo's contribution will be need in the semifinals if Portugal manages to win over Morocco.
By the way, how will Ronaldo's career at the club continue? The last time I saw a team from Portugal was also interested in Cristiano Ronaldo.
This makes sense if the coach sees the quality of the opponents they will face. Not belittling the opponent, but indeed if the coach feels other players are more ready to play than Cristiano Ronaldo it will be very natural to do so.
Morocco is a country of surprises at the moment, Portugal must be more careful when facing them because it is possible they can do what they did to Spain, which is to send Portugal home in this quarter-final. However, there are different strategies shown by Spain and Portugal. Spain indeed they were more patient in looking for gaps to penetrate the opponent's defense, but this actually became a loss for them in the last 16 round. Portugal, on the other hand, was quicker in flowing the ball into the opponent's defense, but the problem was that they had to be more patient because in the first game they lost the ball too quickly. A different strategy will make Morocco think again in the face of Portugal, because the same strategy may not be effective against their opponents this time.
