Paul Pogba, Jesse Lingard, Edinson Cavani, Juan Mata, Tahith Chong, and Lee Grant are among the six players named by the Daily Mirror.
These players' contracts are up at the end of the season, and the Red Devils hierarchy has told them that they are free to go.
On the other hand, the club has notified six disgruntled squad members that their future would have to wait.
United will name Ajax manager Erik ten Hag as their new permanent manager this summer to replace Ralf Rangnick, and the Dutchman will make a significant change at the club.
Anthony Martial, Donny van de Beek, Dean Henderson, Phil Jones, Axel Tuanzebe, and Eric Bailly, according to the source, are all interested in leaving the club this summer.
However, Those six who are alleged to be dissatisfied at the club, on the other hand, have been urged to wait until the transfer window closes because United will not sell them until new additions have been made, and that they will have the opportunity to impress Ten Hag before a decision is taken on their futures.
According to rumours in the Netherlands, Ten Hag wants to bring Jurrien Timber, a highly rated 20-year-old centre-back from Ajax, to Old Trafford.
