Although I am not a Manchester United fan, I think Amorim does not deserve to be called a failure with the squad he is managing.
On average, all players who entered the Manchester United line up in several competitions this season 90% were transfers made by the coach before Amorim.
Next season when the club management provides enough money to shop for players and Amorim does it, that's when we can start to judge how great he is in handling a club as big as Manchester United.
Amorim has succeeded in bringing Manchester United through to the quarter finals and meeting Lyon later will be a challenge for him.
I agree with you. So far Manchester United's performance is still quite bad. However, this is not entirely Amorim's strategy fault. As a coach I think we should give Amorim the opportunity to spend some players in the transfer market this season. We saw several times Amorim complaining about the performance of his squad that could not carry out the expected strategy. Ten Hag really destroyed Manchester United by buying overrated players and now Amorim has to use the players bought by Ten Hag.
