I agree with you, when a team loses, of course the coach cannot be blamed entirely because this is a sport that is a form of cooperation. Occasionally there are mistakes that are purely made by a player, but when a team loses, it does not mean it is entirely the coach's fault because the coach will certainly try his best for his team and the players must also be able to contribute well in order to win the match.
With a greater chance of winning for Manchester United compared to Southampton, I think Manchester United can indeed beat Southampton, but whether they will have difficulty or not facing Southampton, they will certainly do their best for their team in order to win.
In the first season when a coach joins a team and the results are bad, maybe we can give a chance. But if a coach has been with the team for several seasons but the results are the same, maybe it is also worth blaming. Because he has been with the team for several seasons but has not improved anything.With a greater chance of winning for Manchester United compared to Southampton, I think Manchester United can indeed beat Southampton, but whether they will have difficulty or not facing Southampton, they will certainly do their best for their team in order to win.
However, it is not entirely to blame because the management is also one of the triggers whether the team can get good results or not. Because management is also very influential when bringing in new players and becoming players who can contribute or will become players who fail.
And in the case of Man United at this time, I will not talk too much because it all depends on the owner of MU.
And regarding the upcoming match, I have no idea that MU will fail, but I believe the Red Devils will still be able to get 3 points.
