Manchester United coaches are said to be frustrated with the performances of a £72million star after a succession of poor showings for the club.
According to the Manchester Evening News, one United coaching staff member was particularly upset with the quality of the player's performance in the 1-0 defeat at Tottenham last Sunday.
The individual was also hooked when the Red Devils were 2-0 against Everton on Saturday afternoon - with the team going on to salvage a point following his substitution.
Since Ruben Amorim became manager in November, he has completed 90 minutes just five times and been substituted on ten occasions by the Portuguese coach.
