West Ham 2.767/4 v Man United 2.8615/8; The Draw 3.45
Live on BBC One
There are two ways to interpret West Ham's form. You can either applaud a ten-game unbeaten run which is their longest since returning to the Premier League in 2012, or point to four straight draws - every one of which involved them leading after 69 minutes but being held - as proof of dwindling momentum.
In fairness, three of those arrived away to Manchester United and Chelsea and from 2-0 down at home to Arsenal, while controversial refereeing decisions went against them in all four, yet it is inevitable that they won't be as fluid as when winning four fixtures in a row prior to that as a result.
Though the misfortune with officials shows no sign of stopping, the injury situation is a bit calmer, with James Collins, Carl Jenkinson, Sam Byram, Alex Song and Diafra Sakho the current absentees.
If West Ham fans are struggling to know how to interpret four draws on the spin, imagine how much difficulty Man United supporters are having making sense of their springtime progress.
Successive 1-0 victories over Manchester City and the Premier League's hardest-to-beat travellers Everton following decent 1-1s with West Ham and Liverpool hinted that they were on the up, and they shut out title-chasing Tottenham for 69 minutes at White Hart Lane, only to concede three times in the space of seven minutes. The result left them four points adrift of fourth place.
The Red Devils are expected to be without Luke Shaw, Bastian Schweinsteiger, Adnan Januzaj and Will Keane for their penultimate visit to the Boleyn Ground, but captain Wayne Rooney has a shot at completing a comeback after two months out having played for the club's U21s on Monday evening.
The draw is the longest priced of the three potential 90-minute outcomes at 3.45, but the case for it is by far the most compelling.
West Ham's present run of four consecutive draws has already been mentioned - they won the one before that as late as the 90th minute - but another delicious trend is that they have played Premier League opponents in cup competitions on four occasions this term and every encounter ended level.
The Irons have shared spoils in two of their four clashes with teams above them at the Boleyn, winning one by one goal and losing one by the same margin, and they have drawn their last three meetings with Man United. The pair's previous showdown in east London finished 2-2 in 2013 too.
The guests neither conquered nor were conquered on two of their past three ventures to the capital, tying 0-0 at Crystal Palace and 1-1 at Chelsea before their late collapse at Tottenham. They haven't been defeated in any of their most recent 11 collisions with Slaven Bilic's men, drawing three in four away.
There has been range to the series of referee mishaps in West Ham games over the last month. Sometimes goals are wrongly allowed to stand for their foes, sometimes their own legitimate efforts are mystifyingly ruled out and sometimes they concede penalties when contact is outside the box.
However, debatable and often rescinded-after-the-event red cards are a key part of the saga as well, with six being shown in their dozen contests since the start of February. There have also been four in their last eight FA Cup outings, and two in their past four skirmishes with Man United.
