The 22-year-old's existing contract is due to expire next summer, but the Netherlands international has allegedly been offered fresh terms by the 20-time English champions.
According to Football Insider, a new three-year deal has been placed on the table, although the versatile defender will not make a decision on his future until the start of January.
The report claims that Fosu-Mensah, who has only started four times for the Red Devils, first wants to take a look at what other potential offers arrive.
The Dutchman was reintroduced into the first team after the lockdown period and has featured on two occasions for Ole Gunnar Solskjaer's side during the 2020-21 campaign.
Fosu-Mensah, who will be free to discuss terms with other sides at the start of January, has made 29 appearances for United since debuting in 2016. body check tags ::
