Amorim is building a new dynasty. Many big names are starting to be discarded. The last I heard was Marchus Rasford who will be loaned out by Barcelona with a permanent clause. I see Rashford is actually good, I think Man United can regret if he really leaves.
When he was with Aston Villa he actually performed well too. But it seems Amorim is not satisfied with his efforts. Amorim thinks he is too weak and doesn't want to work hard according to Amorim's instructions. I think if he does go to Barcelona he will have no trouble adapting.
