But Ten Hag said he is too important to lose despite his struggle for form, which continued in a 2-1 defeat at home to Brighton in the Dutch coach’s first match in charge last weekend.
“He’s really important,” Ten Hag said. “You have seen from the first day I’m here, I’m really happy with him, I don’t want to lose him.
“He’s definitely in our plans at Manchester United.”
The speculation around Rashford comes as United continue to struggle to bring in signings of their own.
The potential arrival of Juventus midfielder Adrien Rabiot has also been criticised by supporters for lacking ambition.
Asked if he will have the squad he needs by the time the transfer window closes on September 1, Ten Hag added: “We have to. I am convinced we will have.”
The five-time Ballon d’Or winner came off the bench in the second-half as Ten Hag’s tenure got off to a losing start against Brighton.
Ten Hag said Ronaldo would be involved at Brentford on Saturday, but would not be drawn on whether he will start.
“He had a good training week,” he said. “He’s had two half-games and for the starting XI we will see tomorrow. It’s my decision, I keep it.”
Another defeat would pile more pressure on the former Ajax boss just weeks into his reign at Old Trafford, but he accepted the scrutiny that comes with being United manager.
“I know there is always pressure, I have the experience, how it is,” he said. “I know we have to win every game, I know the fans, I know everyone expects Manchester United to win every game.
“We have to deal with that and all I can do is prepare the team as well as I can this weekend.”
