Manchester United boss Ole Gunnar Solskjaer says Paul Pogba "is not being sold in January" and also denied he was meeting Red Bull Salzburg striker Erling Haaland on Friday.
Midfielder Pogba's return from injury has been delayed by illness, and he is unlikely to play at Watford on Sunday.
Meanwhile, reports on Friday claimed Haaland had flown from Stavanger in Norway to Manchester with his father.
But Solskjaer said the 19-year-old was "on a Christmas holiday".
"I don't think he is en route here," said the 46-year-old of a player he managed when in charge of Molde. "You can't fly anywhere from Stavanger.
"I can't comment on other teams' players. You get a lot of speculation."
France international Pogba was expected to return to training last week after recovering from the ankle injury that has kept him out since September, but he was struck down by illness and his symptoms worsened on Sunday.
However, Solskjaer said the 26-year-old is edging towards a return and will not be leaving Old Trafford next month.
"He is not being sold in January," said the United boss.
"I hope he will play before the end of the year, but I am not going to push him. I can't risk any setbacks or injuries."
Pogba's agent Mino Raiola has told the Telegraph Pogba wants to "win prizes" with Manchester United and the club did not let him join Real Madrid.
"Paul wants to be successful and happy and wants to win prizes and he would love to do that with Manchester United," Raiola said.
"Okay there was big interest from Real Madrid and Manchester didn't let him go. We didn't make a fuss about it and he didn't make a fuss about it because I work in accordance with the player."
