So at this moment, at least the attitude of maturity and professionalism should be applied because if not, then the dispute between them will become more difficult to overcome. Moreover, Manchester United position at this moment is also bad and also, Manchester United will face a more difficult competition than last season. Therefore, Erik ten Hag should be more assertive and do not need to lower his ego, because as a coach, he must have a firm and disciplined attitude to build the team even better. Because after all, the coach has authority in the team, so it would be inappropriate if Erik ten Hag lowered his ego, because it would make him weak. But indeed, basically Manchester United has started the season not well, so it will indeed be difficult to recover quickly.
Erik ten hag's ego is and has never been the problem. He is the head coach ad as such he need show some level of authority so as to get the team in oder and do that which he wants them to do as the success of the team is mainly rested on his shoulders and decision he makes. If the players will not heed to his instructions and directions as the head coach what ever happens is still blamed on him regardless.
The player seem to have some level of rifts amongst them which will definitely affect their performance on the long run. It's time they drop all those and act professionally for the success of the team as the continual exercising of such will continually affect their productivity, this is most obvious amongst the defenders as they show no chemistry amongst themselves at some point.
Ten hag need to take more stringent measure as they have even more tougher teams ahead to tackle and needs more of their collective efforts to be able to succeed, but if he tolerate any form of continues show of incompetency amongst player he should be sure of not doing so well this season, moreover he is not a bad coach considering his performance so far with the club.
