Ronaldo's pressing stats are awful and when I say awful it's literally worst performing attacking player in the PL and CL-kind of level. Even Leo "walking around the pitch all the time" Messi is outperforming him comfortably.
Just check Pressures and Succesful Pressures per 90 minutes and you will find him close to rock bottom in both competitions, it's definitely an issue and people saying "he is fit" or "look how he is running around" don't really seem to understand the issue.

I am pretty sure he like the rest of our players can improve in that area under a proper manager but it's important to note that he is miles off an even just bad level so far.
Putting Ronaldo into the team for his goals means sacrificing other dimemsions to our game and that doesn't even touch things like touches or build up-ability in our game where he is also one of the worse performers in our team.
Everyone wants us to play like Rangnick or Ten Hag wants to, everyone wants to see that "Gegenpressing" it's fair to say that it might not work all that well with Ronaldo in the team.
