Erik Ten Hag has been able to transform the team mentally, physically and tactically. He has also been able to help improve some of the players who have been performing poorly, players like Darlot, Rashford and Fernandez have been playing alot better in the past 4 games so are commend Ten Hag's efforts. Ronaldo's situation I believe is just for the main time and in a short time everything will fall in place and he will get back his position in the starting eleven.
Ronaldo is part of Ten Hag plans actually. But for some reason that makes Ronaldo want to leave Man United and he throws a tantrum to make his wish come true (he left the stadium when the match was not over in the pre season match), this makes Ten Hag choose to bench Ronaldo. After all Ten Hag is the boss and it's right that he should teach Ronaldo a lesson. If Ronaldo can do some introspection and showing good progress, I don't think there is any reason for Ten Hag not to choose Ronaldo as a starter.
I am happy for Manchester United and and I am happier for their coach Erik Ten Hag. Within a short time, he is able to transform the club mentally and tacktically. The players which use to be laxy are now working their ass out there and they can charge football unlike before they stroll in in pitch. the winning spirit of Manchester United is restored in the players. That is a good work done by the coach, the club is able to face any other football club now.
The problem of Ronaldo is a different, Eric is not punishing Ronaldo for any reason, in fact in the beginning of the season he gave Reynaldo some chances but the team failed to win. It is obvious that Ronaldo is not fitting int the coach strategy. The coach is playing high-pressing football and Ronaldo is aged to play that kind of football that is why he has to come in second half to complete the game, when the team must have gotten a win. Same with Casemiro and Maguire.
