Cristiano Ronaldo not being able to play a role for his team, I don't think that's it. It's not surprising that his not been delivering on the job as expected and by that, I mean the goal scoring but, his still very much a leader and the hope of the Portuguese team as he has always been.
I was thinking maybe that Christiano Ronaldo was reserving all the energy to showcase himself in this world compition and this was why he couldn't perform since the beginning of the premier league season, but I'm yet to see that in action. So I do believe that after some of their games, the team realized the need to start building a new team without Ronaldo , So this is what you can see from the team entire Portugal team performance.
