In the case of Amorim, I think it is obvious that he has a plan and a style which clearly the current players don’t fit in. Amorim needs fresh legs and players that will fit into his style which means signings need to happen and this kind of overhaul cannot be effectively carried out through a January transfer window. I expected the club’s management to instruct Amorim to stall his style for the moment since he doesn’t have the players to execute it. At this time surviving relegation should be the ultimate goal.
If we continue believing all the players aren't fitting into amorims strategy and pattern of playing then we may be aswell assuming a complete overhaul should be done on the team which I don't see as a feasible thing to do because it will cost the team so much that they are actually not even going to consider that as an option but then I think it's time amorim begins to look into making an adjustment so he too can get some players with whom he can work with and then make the necessary changes as the needs arises, he can aswell consider rotations for better productivity.
The root of the problem that befalls manchester united today is actually too big to be uprooted even by amorim , all the problems instilled by ten hag before have taken root so that indeed amorim needs a long time to fix their squad problem, a complete overhaul at the end of the season can still be used as a solution because then Amorim has the freedom to bring in players who fit his criteria and desires, so that way he can form a team that suits his vision and mission, although it takes a lot of time and money to build the perfect squad, of course it will be better than they continue to patch up every weakness that exists like today.
