The Red Devils paid Crystal Palace £50m for the defender in the summer of 2019, and he has made 190 appearances for the 20-time English champions in all competitions.
Wan-Bissaka benefitted from injury problems at Man United last season to make 30 appearances in all competitions, but he could struggle for action during the 2024-25 campaign if head coach Erik ten Hag has a full defensive group to choose from.
The 26-year-old is out of contact next summer, and he is currently being heavily linked with a move away from Old Trafford, with West Ham United said to be interested.
According to journalist Florian Plettenberg, Man United could let Wan-Bissaka leave for £10m this summer, which would represent a £40m loss on the fee that they paid for him five years ago.
Man United 'prepared' to accept £10m for Wan-Bissaka
Wan-Bissaka has been involved in both of Man United's pre-season games this summer, but Diogo Dalot is once again set to enter the new campaign as the club's first-choice right-back.
Should Wan-Bissaka depart, it is highly likely that the Red Devils would be in the market for a replacement, with Bayern Munich's Noussair Mazraoui said to be a target.
However, West Ham are also thought to be keen on Mazraoui, with the Hammers potentially dropping their interest in Wan-Bissaka in order to sign the Morocco international.
Bayern are said to be willing to met Mazraoui leave for as little as €15m (£12.6m), with the 26-year-old therefore viewed as a bargain signing this summer considering his age and experience.
Will Lindelof, Maguire leave Man United this summer?
Man United have boosted their centre-back department this summer with the signing of Leny Yoro from Lille, and the 18-year-old made his debut against Rangers on Saturday.
Jonny Evans has also signed a new one-year contract, while the club remain in discussions with Bayern Munich over a potential deal for Matthijs de Ligt.
As a result, it is expected that one of Victor Lindelof or Harry Maguire will leave, and as it stands, the former is more likely to be on his way out of the club.
Maguire is again said to be willing to stay this summer and fight for his spot next term, but Lindelof could move on to secure regular starts at this stage of his career.
