The pacey Nigeria-born 20-year-old was rated as rated as one of Palace's top prospects before the London club were forced to sell him amid a financial crisis 20 months ago.
Wigan regarded their £2.5million capture of the youngster as a coup and his performances this season have underlined his potential.
Moses has started all four Barclays Premier League games and is keen to continue in the side as Latics travel to his old stomping ground, Selhurst Park, in the Carling Cup second round.
Moses told Wigan's website, www.wiganlatics.co.uk: "I was there for four years.
"Obviously I am not there now but respect to the team, it is a good club it will be nice to go there, feel the pitch and see how it is.
"It is a good team but we need to go there and win the game, obviously.
"It will be strange because I was there before playing for them, and now I am a Wigan Athletic player.
"It will feel weird but that is what football is all about, you are in one place one moment and then the next you are somewhere else.
"But I just want to go there and enjoy it."
Moses appears to be making the most of the extra opportunities presented to him by manager Roberto Martinez this term, perhaps as a consequence of the departures of Tom Cleverley and Charles N'Zogbia.
He still has the best part of two years to run on his contract but Wigan have already opened talks in the hope of extending his stay at DW Stadium.
Moses said: "I think this season has gone well and we have started well compared to last season.
"I think I am having the best time of my career at the moment.
"I want to be starting every game, playing my football and enjoying myself at the club.
"As long as I have a chance I want to take it and enjoy myself."
Martinez, whose side were beaten 3-0 at Manchester City on Saturday, is expected to hand debuts to new signings Shaun Maloney and Patrick van Aanholt on Tuesday night.
Albert Crusat could also come in for his first start but defenders Emmerson Boyce, Antolin Alcaraz and Steven Gohouri are all out.
