Odds of 150/1 that this weekend's FA Cup final mirrors the 1990 clash with a score of 3-3 after extra time according to Ladbrokes.
Other throwback wagers include the 10/1 offered that United lift the trophy before going on to win the Europa League next season, while it's 16/1 that two or more goals are scored in extra-time.
Those who think Palace boss Pardew will turn up in his 1990 kit can take 100/1.
Back then Palace faced a United side with a manager under the cosh, and it's 5/2 Louis van Gaal wins the FA Cup and stays on in charge at Old Trafford next season. Odds of 2/1 suggest we may well see 'king' Louis crown himself with the trophy lid, with 4/11 the price he gets his hands on it by any means.
United old boy Wilfried Zaha is 12/1 to score the winner for his new side, with Palace 9/2 underdogs to upset the odds during normal time.
Richard Marsh of Ladbrokes News said: "Anyone who thinks the 2016 final will mirror 1990 in more ways that one will land a handsome payout. As it stands the odds firmly favour history repeating itself in terms of the cup winner, but it remains to be seen if that would be enough to keep Van Gaal in a job."
