Bournemouth performed very well and was able to take advantage of every weakness of Manchester United with the right strategy, I admit that against the red devils squad, Bournemouth was better prepared than Manchester United, but surely you know that the English league is a very competitive league, so the team that is not ready will certainly get the consequences (defeat) in a match, so I think it's not a good reason for us to say as the cause of the bad results achieved by Manchester in the match.
Indeed, perfect teams in the English league so far, but compared from manchester city, I actually see that manchester united has the worst problem, manchester city has a bad defence after losing Rodri but they still have an impressive and sharp attacking line in my opinion, while manchester united precisely they have many weaknesses in every line.
The problem that Manchester United currently has is that their current coach, Amorim, has not yet finished testing several strategies and player rotations which he hopes will bring about better changes, but instead it makes Manchester United seem like they are not making any progress at all. That is, in one match they are good but in another match they are bad again. And it goes on like this.
Just try to pay attention to the composition of the players in each match. The starting eleven used continues to be changed. Which means Amorim still hasn't really decided who in the squad he will actually include in the main squad. This is more similar to testing in pre-season matches. Unfortunately we are in the middle of a season that is almost in progress. And if Amorim doesn't find a suitable composition in the near future then it will only make this team fall deeper. But I hope Amorim has taken this possibility into account.
Amorim has brought new hope for Man United, but unfortunately Amorin has not been able to realize that hope, and Man United still looks stagnant, they appear inconsistent when on the field, as well as the results obtained. and you are right about Amorin that for now he is still looking for a scheme and strategy that fits the team. on the one hand maybe Amorin is also sorting and choosing players who can still survive for Man United according to what he has planned, and maybe after the transfer market opens we will see Man United will release players again and also recruit many players, to be able to realize what Amorin has planned.
