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.
It problem is the supporters have been really patient but they are yet to see results so it's definitely getting them weary already, because they wouldn't have to wait all season before they will get to see the results they wish to see because such time is definitely not available on their side.
Asides the carbao they had last season, they have had almost no trophy in a while now and the fans are begging to be scared seeing their recent performance that they may end this season aswell with no trophy again which is definitely not what they want to see, klop needs to start getting back on his feet knowing too well that the fans and supporters are hope to see better results than he has now and even the team would definitely want to be back to their glory days.
