Manchester united supporters should be patient with the coach because there's completely no other better prominent coach out there without weaknesses. Even the almighty Pep Guardiola and Jurgen Klopp often records defeats in league games. Erik Ten Hag is simply doing his best to redeemed the club from their struggling moments and ensure they are in good shape, one of the major reasons he will massively be involved in the January transfer market. Sacking a coach is not the problem, the main problem are the players whose performance are unprofessional against elite oppositions.
Truly there is know perfect coach but however as we have different coaches that is how we also have different quality of coaches and we cannot compare some of them to others because there are far better than them, so however in times of Manchester United I no that there coach is trying in the little way he can but his coaching patterns is not suitable for Manchester United.
However we can never compare Pep Guardiola with Manchester United coach because Pep Guardiola is far better than him, perhaps if he should handle Manchester United for just a season you will see the impact he is going to make.
