The Eagles sold the England international to the Red Devils during January, but retained him for the remainder of 2012/13 in a bid to aid their promotion push.
This worked, and after winning the play-off final, Holloway wants him back again.
United chief David Moyes is yet to confirm his plans for the livewire, but it is thought that first-team opportunities may be difficult for him to come by at Old Trafford due to the presence of a number of established players.
This may tempt the Red Devils to allow him to move away on a short-term deal to boost his development.
Palace would appear to be the ideal destination, with the player having emerged from their youth set-up to become fully immersed in the senior squad over the course of the past few years.
The 20-year-old would be guaranteed first-team football, whilst having the chance to acclimatise to life in the Premier League.
Both Fulham and West Ham are also keen to take Zaha on a loan deal, and are willing to offer him ample chance of playing time.
Does a return to Crystal Palace make sense for everybody?
