Pogba has been strongly linked with a move away from Old Trafford as he enters the final six months of his current contract.
He can talk to clubs outside of England ahead of a potential blockbuster free transfer at the end of the season.
It had been reported that Man United offered the Frenchman a new contract to prevent a free transfer.
The reported contract was worth a massive £500,000-a-week, which would make him the highest-paid player in Premier League history.
But a spokesperson for Pogba has dismissed claims of a new contract, saying he's fully focused on returning to action following his injury.
"To clarify media reports, Paul has not been offered a new contract in recent months," the spokesperson told the Daily Mail.
"Paul is fully focused on his recovery from injury with the aim of helping the team as soon as possible."
Pogba is on the sidelines through injury after picking up a knock in the November international break.
Ralf Rangnick, who has yet to call upon the 28-year-old's services since joining the club, said it will be another 'four or five' weeks before he's back in training.
"As far as I know, I was told a week ago, it would be a minimum of at least another four or five weeks before he is fit for training again," he told the club's website.
"I saw him this morning before the training session, he was in the locker room, and I hope he will be back as soon as possible.
"Right now, he’s not been part of the training group and, even if he was back whenever, two, three or four weeks, it will take some time.
"It’s one thing to be training fit but, on the other hand, he needs to be fit for the match and competition in either the Premier League or the Champions League and this will still take some time."
Pogba returned to Man United from Juventus in 2016 for £89 million.
Though it appears another Old Trafford exit could be on the cards.
