It can be shocked information if you dig and find total money spent for player transfers by Manchester United and Chelsea recent years. It's not correct to say Manchester United did not spend big money in the last summer, so their failure in this season is partially from their failures in transfer market in the last summer and previous ones too.

But it's not about how much money the two teams spend. And if you understand what I'm saying, you won't have any excuse to compare Chelsea and Man United.
Despite Man United spending big money last summer, are the new players who came in Amorim's choice?
Compared to Chelsea who spent a lot of money to buy new players who have been selected by Enzo Maresca.
Actually it is very clear that I said that statement because it is not only about money but running a squad without having the desired players is not an easy task. So for now I will not compare the two teams which I think is very unfair and it will be fairer if we compare in the next season when Amorim has the opportunity to bring in the players of his choice.
If it is Ten Hag, then it is fair to compare Man United with Chelsea because he is the one who cost Man United money at the start of this season. But in fact, Ten Hag has been kicked out and replaced with Ruben Amorim and sadly there is not much money left for him, so Amorim can only sign Dorgu alone, and for the changes that the boss wants, Amorim is forced to use existing resources. It is obviously not easy to execute a strategy that is completely different from before by only relying on existing players.
So if you want to compare, just wait until next season (assuming Amorim will get full financial support from the boss).
