Honestly Manchester United has struggled for the longest and I agree with you that ordinarily the culture of the club do not allow them be in such a position this long as the pressure from the team alone keeps everyone on their feet and this includes the coach and the player but it keeps looking like they now settle for the compromise and nothing is happening, there is hardly a noticeable progressive improvement, only loads of promises and unending hopes and expectations that almost never comes to fruition, a new coach all players may not be the solution but a system that keeps the current coach and players on their feet to birth results.
Their struggle ended last season. The changes that was made in the Manchester United squad, so far from the coach to the players will give Manchester United a UCL football next season. I noticed a lot changed when they played against Arsenal. They are more of a threat in any opponent 18 yard box compared to last season. Well, the first 4 place is not going to be easy this season. All the teams are doing better. Chelsea, Liverpool, Arsenal Manchester City and other clubs. Its going to be difficult for Manchester United this season.
