New Manchester United manager Erik ten Hag has already made a decision on Wan-Bissaka and wants to move him on from Old Trafford this summer.
The 24-year-old is not part of his plans at Old Trafford and has been asked to find a new club in the upcoming transfer window.
Crystal Palace are interested in taking the player back to Selhurst Park on loan, but Manchester United want some sort of guarantee over a permanent sale.
However, it has been claimed that Palace would only be interested in signing Wan-Bissaka on a temporary move.
Nathaniel Clyne is expected to sign a new contract, Joel Ward still has a year left on his deal and Nathan Ferguson is still at Crystal Palace.
The club do not have the space to try and sign Wan-Bissaka on a permanent deal this summer.
The Manchester United star has other suitors with Atletico Madrid believed to be interested in signing him.
