One failed United player to play in this Amorim team?

You are not wrong, but the OP said players who failed at United, in my mind that meant anyone, or was it about players who failed at United but were actually good, someone like Mata or Pogba?
The way I read - players that failed but we think could still work this time around.

Mkhitaryan didn't work both for us and Arsenal, so I don't think he will be any good in a physical league like EPL at the age of 35. Just my opinion
 
Pogba didnt fail so he shouldnt be named. I would love him in this team though.
He was amazing if you ignore
1. Being extremely inconsistent
2. Being injured quite often
3. Him and his agent being extremely toxic and literally damaging the club for selfish reasons
 
Daniel James, Pellistri could play RWB. Fred would be very good in Midfield. Lukaku also.
 
Pogba and Di Maria are the obvious choices. If you count players any time of their career, obviously Schweinstiger, Falcao, or Sanchez.

Injury-free Bayern version of Owen Hargreaves a good shout too.
 
I was going to say this. Probably the perfect role for him. But he would need an overlapping wingback to be fully effective.
Would be awful, to weak and slow to press. Amorim's 10 need to be energetic. Being fair I dont think Mata would fit anywhere in today's top clubs you need a certain amount of physicallity to compete and he's build like a 13 year old.
