I don't know, I think it would be better if Amorim considers bringing back some of his players that has improved in their performance since they were on loan, Anthony is in hot form now likewise Greenwood, I understand the situation that is affecting the return of Greenwood but I think Amorim should think about bringing back Anthony into the team instead of signing a new player that would start working to adapt to his tactics.
It is not certain that Antony fits the style of play implemented by Amorim so I think it is better for Amorim to focus on building the team without having to consider some of the players they loaned to other teams because it is clear the reason Manchester United loaned some players because they did not develop with Man United even though they are now in their top performance with the new team but it is not necessarily the same if they return to the Manchester United team.
I also think so, even though the loaned player has improved his performance with his new team, it is not necessarily the player who is the problem. It could be because the loaned player does not fit with the coach, or even the playing style does not fit with the other players on the team.
I would actually support United selling Anthony to Betis, who would benefit from his arrival on the team. That is if Betis is interested.
