60million summer signing Mount has started only one of the last six United games and he is yet to tally a goal or an assist in his seven appearances for the club.
Mount, 24, has been omitted from the last two England squads by manager Gareth Southgate and he is not assured of a recall for United in their Premier League fixture against Luton Town on Saturday.
Scott McTominay, available for transfer in the summer, has regained his place in the United side at the expense of Mount while Ten Hag has entrusted Christian Eriksen over the former Chelsea creator.
Mount missed six games with a hamstring injury in August and September but he has not convinced since he returned to the team.
“No. Hasn&apost changed at all,” Ten Hag said, “but he started the season, then he got injured, it&aposs the worst moment for a new player to get injured because it stops the reintegration process and that was definitely a setback for someone like him. And now he has to find his place back.
“He had some starts, also recently, last week against Newcastle, for instance. But there are always reasons and sometimes the injury, then other players coming in doing well, you have to wait for your time to play.”
United have had their worst start to a season since 1973-74 – when they were relegated – having lost nine of their 17 matches.
Luton arrive at Old Trafford this weekend for the first time since September 1991, having held Liverpool to a draw at Kenilworth Road last week.
“Finally, it is about the end result and we have to win every game,” Ten Hag reiterated. “So we are very disappointed at losing any game.
