With the relationship between Pogba and United boss Jose Mourinho thought to be severely strained, talk of a possible switch to former club Juventus or Spanish giants Barcelona has dominated plenty of back pages in recent weeks and months.
According to 'talkSPORT', the 'Red Devils' have already begun eyeing up potential replacements for the World Cup winner, in an attempt to be prepared for all eventualities.
Sergej Milinkovic-Savic (Lazio)
The powerful Serb has been heavily linked with a mega-money move to a European heavyweight for some time now having established himself as one of the best midfielders in Serie A. Not midfielder scored more than his 12-goal tally in the Italian top flight last season.
Ivan Rakitic (Barcelona)
With the Croatian having rejected interest from PSG in the summer to remain at the Camp Nou he is potentially the most difficult player on this list to prise away from his current club. A player who seems to have got better and better with age, the playmaker remains a vital part of Ernesto Valverde's plans and baring a huge change of heart he is likely to be beyond United's reach.
Abdoulaye Doucouré (Watford)
A key part of Watford impressive start to the Premier League season, the French-born midfielder has caught the eye of plenty of bigger fish. a Powerful and dynamic player, Doucouré has laid on two goals in his four Premier League appearances to date this season.
Thiago Alcantara (Bayern Munich)
The German champions are known to be open to cashing in on the midfielder should they receive a decent offer, having told the player as much during the summer. Whilst more likely to return to his homeland, Thiago could be tempted by a Premier League adventure as he goes in search of a regular starting berth.
Tanguy Ndombele (Lyon)
The youngest player on the list but by no means any less appealing than any of the other names mentioned. A versatile and adaptable midfield player, it is believed to be only a matter of time before he breaks into the French national side.
Adrien Rabiot (PSG)
Perhaps the most sensible signing financially, with the Frenchman set to be available on a bosman at the end of the season. However, with rival interest from Barcelona and Liverpool, it would likely take a mega-money offer to convince the France international to reject the overtures of two more long-term suitors to make the switch to Old Trafford.
