ESPN says Pogba has less than a year left on his United contract, and is free to speak to clubs about a move in January.
Agent Mino Raiola is continuing to explore avenues of a potential departure this summer, with Barcelona the latest club he has spoken to.
While United want to keep Pogba, they are still exploring alternative measures should they lose their talisman.
One name linked is Tchouameni, the Monaco midfielder who partnered Pogba in the middle of the park during France's recent Nations League success.
He is on the radar at United, with a bid of €50m to €60m (£42m-£50m) needed to bring the Ligue 1 side to the table.
