Amorim has endured a mixed bag of start to life at Old Trafford since arriving in November, having lost two of his first five games in charge.
The Portuguese has been somehow forced to rotate his starting XI on a regular basis in his opening weeks, indicating that he is not convinced by the current squad, hence the need for reinforcement in the upcoming emergency window.
It is understood that Amorim only views 8-9 players in his current squad as untouchable. This list includes Amad Diallo, Kobbie Mainoo, Noussair Mazraoui, Matthijs de Ligt, Leny Yoro and Andre Onana.
However, a report on MailOnline cited by AhotorSports suggests Ruben Amorim has been told he must sell players before making any signings.
Marcus Rashford, Manuel Ugarte, Bruno Fernandez among others reported to be making their way out of Manchester United.
