It will be very difficult to do because in the end when talking about this, apart from the players themselves there must be the role of the coach as a spirit booster for them to try to get out of their current poor performance and Ten Hag still cannot do that now so the chemistry between the players and the coach still has a gap that makes teamwork in the squad also disrupted.
I think it would be wiser for Rashford to now realise that indeed this season he is very bad at playing. This season I even see his ego getting bigger where he rarely sees other players and only focuses on dribbling and forcing the opportunities he has. This pattern must be changed and not only Rashford is like this but also Bruno who must improve his performance.

For Antony he actually has good potential, it's just that he's too emotional and the problems at the beginning of this season are still bothering him which makes his performance decline in the current season too. The internal problems of Manchester United are too many and honestly I think things like this are difficult to control if in the end there is no awareness from the players and coaches.
