If you say Manchester United should employ a new young manager then we are starting the rebuild all over again and This is what we have been doing for the past 10 years that Sir Alex left the club. Manchester United need to calm down and restructure from the hierarchy and give Ten Hag sometime and back him with signings they see fit
I think if in the end it can make Manchester United better then why not because in the end it is a choice that can be better.
At the moment whatever choice is taken everything still has a risk when Manchester United are looking for a new coach then surely an overhaul will be made to make Manchester United fit the criteria of the new coach and that needs to be re-adapted. If the other option is to keep Ten Hag actually it also has the same big risk where I will not be too surprised if there will be more internal problems with players and coaches just like what happened to Cristiano last season and Sancho this season because Ten Hag's level of ego is quite large and he cannot embrace young players well.
