If united board have made up their mind and appoint ten hag then should be given full backing. No half hearted measures. Team lacks belief and if next manager not started well then these players easily topple the manager.
So whatever happen result wise only measure will be about how well team play as a unit and how team responds to set backs.
Ten hag has the ability to coach players individually for their specific weaknesses and able to make underperforming players into good ones. Not totally relying on super stars which is very good for united in this stage.
These overpriced super stars are double edged swords and could be the reason for united s downfall after saf retired.Look at the players came after saf left Pogba,mata,matic,Maguire,Lukaku,Falcao,Di Maria,schweini,Cavani,Ronaldo,Sancho. All these players were great before joining united but not single one of them able to perform consistently for team or improve the team as a unit. That's why United struggled.
With ten hag he will probably bring back that knack of finding unearthed gems.Not overpriced superstars.
