Paddy Power are offering new customers the chance to back either the Gunners at 4/1 or the Red Devils at 9/1 for Wednesday's Premier League clash
Arsenal - although now 6/1 (7.0) to win the Premier League after losing 5-1 to Liverpool on Saturday afternoon - can still lay claim to being legitimate title contenders.
Wenger's men are just two points behind leaders Chelsea with a game in hand; a victory on Wednesday could elevate them back to top spot.
The Gunners are an industry-best price of 11/8 (2.38) to get back to winning ways at the Emirates but Paddy Power are offering new customers the chance to back the home side at a massive 4/1 (5.0).
Not only is this price a big enhancement but given Manchester United's form, it's increasingly difficult to make a case for David Moyes' men and the home side are sure to come in for support given the fortunes of the two clubs so far this campaign.
Despite United having lost their last three away games in all competitions, anyone without a Paddy Power account who is considering backing David Moyes' side to complete an unlikely league double over Arsenal can do so at 9/1 (10.0).
That is an offer almost three times the 13/5 (3.6) that is currently the best the layers have to offer and an unprecedented price that would have been unthinkable during Sir Alex Ferguson's time at Old Trafford.
There's a money back special for existing Paddy Power customers, too. Losing first/last goalscorers, correct score and scorecast bets will be refunded by the Irish bookmaker if former Arsenal frontman Robin van Persie scores the last goal of the game.
The 30-year-old, who spent eight years at Arsenal, has scored against his former club on the last three occasions that the two sides have met, firing the last goal on two of those occasions, so this money back special could well reward customers whose longer priced bets don't prove correct.
