The coach has to do what's right for the club in terms of fitness and appropriate selection. When he starts scoring then it'll all be on the winger's to sit tight, benching Ronaldo is way useless
Manager has to do the right thing for the team and ten Haag is doing that for the team. He is measuring players equally based on what kind of performance a player puts on the team. That requires guts which earlier managers didn't had. I don't think they will bench Ronaldo completely as they are out of attacking options and I think ten Haag plans is to use him as a striker in attacks at later stage maybe a bit with change in attacking strategy so I think somewhere there is a role for Ronaldo still. The thing is how Ronaldo is handling this situation as he obviously want to start and complete the game but manager always wants the best for the team and so at the moment he is not in starting picture right now.
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.
