The Chelsea attacking midfielder has only one year remaining on his contract at Stamford Bridge.
With contract talks at a standstill, Mount is set to leave the club this summer.
Per The Telegraph, the 24-year-old is emerging as a key option for United this summer.
The Red Devils believe Mount can ease the offensive burden on their midfielders, while adding more of the pressing and tenacity that Ten Hag demands from his players.
Chelsea are said to want around £85 million for their homegrown superstar.
However, United are going to bid in the range of £55 million, given Mount's contract situation.
