The playing pattern implemented by Amorim has not fully integrated with the Man United players, he has also not found the right formation to improve the quality of their game. Two consecutive defeats during Amorim leadership forced him to work hard to get better results in the next match. Maybe he should stick with the current squad before the January transfer window opens, he has also identified various shortcomings in his squad, maybe Christian Eriksen and Antony will be released to other clubs to increase the budget to strengthen his squad.
It is okay to release the two players you mentioned to other clubs in the transfer window later as long as Manchester United can ensure to get two other great players who can fill important lines that are still considered weak at this time. Because Amorim not only has to be able to polish the existing players, but Amorim also has to choose the right tactics and formation for the current Manchester United players because in general Manchester United is still in a very bad position at this time in the standings table.
