Posh are the favourites at 6/5 with Orient at 23/10 and a draw also at 23/10.
Fancy Orient to repeat the 3-1 scoreline that they achieved back in November at London Road? You can get 25/1 on that or David Mooney to score from outside the 18-yard box at 14/1.
Orient to win from behind is priced at 17/2 or if you fancy Mooney and Kevin Lisbie to both get on the scoresheet as was the case at MK Dons you can get it at 13/2.
