Arsenal travel to Old Trafford on Sunday in the Premier League (16:30 GMT) and face a United side without a number of key players including long-term absentees Lisandro Martinez, Luke Shaw and Mason Mount.
Amorim said it was unlikely any other injured players would return for Sunday, but did raise hopes that Amad Diallo could be back before the end of the season.
«I think it is just Amad [who is out long-term],» said Amorim.
«Even Amad, we will see the end of the last month [of the season].
«I have the hope to have Amad before, we will see.
«Kobbie [Mainoo] can return. [Harry] Maguire, we have to be careful, Manuel [Ugarte] will return, and I think Mason [Mount] and Luke Shaw can return also.»
