The Daily Mail says Pogba left Old Trafford on Wednesday night with the stony-faced expression of a man who continues to be less than happy with life at United.
Asked to comment on his bit-part role in a 2-2 draw with Arsenal, the club's record £89million signing shrugged and said "what do you expect me to say?" before departing the stadium.
Pogba had been benched for the second time in four games.
The Frenchman received a mixed reception when he came on for Jesse Lingard in the 75th minute and was first out of the exit afterwards.
