Well, his predecessor, Erik Ten Hag just got sacked from Bayer Leverkusen only after 2 games, so I don't know why Man United is waiting that long

Leverkusen's sporting director said that they felt things were going in the wrong direction, so they decided to act quickly rather than wait till the situation gets much worse. Maybe United should take the same approach. If there's no chemistry between Amorim and players and if there are no clear signs of improvement, maybe it's better to call it a day and let him go. But they know more than we do, so if they think Amorim has a plan and they're satisfied with it and they are willing to wait for the results, they should give him more time.
Even Manchester United decided to sack Amorim. Who will be the right coach that Manchester United will bring in, someone they are sure won't lead to the same problems that recent coaches have faced? It just seems that Manchester United’s performances are getting worse as they bring in new coaches.During Ten Hag’s first season, I don’t think Manchester United’s performances were as poor compared to Amorim’s. The best thing Manchester United can do now is to leave it until the end of the season and give Amorim specific conditions. If he does not meet those conditions, then maybe he should be sacked.But sacking Amorim at this moment may not solve any problems, considering the way Manchester United players are currently performing. Even without a coach, I expected them to perform better in some matches just like the match they played against Grimsby.
From the look of things Chelsea is already a threat to so many teams, just look at how they performed in the club world cup, the chemistry between the team is something else. Last season in the first half of the season, the team solely depended on mainly one player which is Palmer. But from their strategy and way of playing, they don't depend on just one man anymore, they play more as a unit and look for spaces to exploit from various angles and from different players.
Chelse great performances was really noted in the club world cup, and show that chelsea have one of the best squad
but know that without Certain players I don't think the Chelsea squad will be rated highly or seen as a threat to big teams. Despite that, Chelsea have not lost any matches this season. However, I'm not so convinced by the players or the kind of football they always play when Cole Palmer is in the squad.currently, it looks like Chelsea don't depend solely on Cole Palmer and other key players, but if they face stronger teams without Cole Palmer, you'll see that Chelsea's most important player is missing.
