Amorim has pointed to the standards of some younger players he had to use last season as evidence he was working with tools that were simply not capable of doing the job he needed.
Arguably, that is still the case.
United have deliberately chosen not to release details of whether Noussair Mazraoui, Bryan Mbeumo and Amad Diallo will be available for the Bournemouth game amid uncertainty over their release for Africa Cup of Nations duty.
However, with Matthijs de Ligt and Harry Maguire currently sidelined through injury, it seems likely 20-year-old Leny Yoro and 19-year-old Ayden Heaven will be part of his three-man defence at some point over the next few weeks, which is not ideal given their inexperience.
Yet sympathy for Amorim is limited due to his use of midfielder Kobbie Mainoo, who is yet to start a Premier League game this season and was given an enthusiastic reception by United’s travelling fans when he was brought on during the 4-1 win at Wolves.
Mainoo is eager to make a loan move away from United next month in an attempt to get more regular football.
Amorim was not keen on that plan in the summer when the 20-year-old had a deal with Serie A title winners Napoli lined up.
He is refusing to say what his answer would be should a similar request be made before the January window closes, but he would welcome Mainoo seeking him out for a chat.
“I had some conversations with him, especially last year, and with other players, but about that subject, no, I didn’t speak with him,” said Amorim.
“I will be really pleased if Kobbie comes to talk to me about that. I just want my players happy.
“I understand every individual has their goals and the frustration doesn’t help anybody.
“I’m not going to say what I would say but I would talk to him.
“I am completely open, that is clear. I have my ideas and that is also clear. I will not change if I don’t believe it but I’m open to speak with any player. I love that.”
