The league's title sponsors have a draw available at 23/10 and the O's 6/5 for victory.
The last time we hosted the O's was in December 2015 in an FA Cup second round replay which saw Scunthorpe win 3-0. We're available at 33/1 for a repeat of that score.
Our last home league win against them was a 2-1 success in March 2013, and it's 9/1 for a repeat of that.
United haven't won at home since late September, and we are 10/3 to win 1-0, 2-0 or 2-1 in the Correct Score Group Betting, or alternatively 11/1 to emerge 3-0, 3-1 or 3-2 victors.
