Manchester United will be aiming to move back into third place in the Premier League by securing victory over a West Ham United side that is looking to improve on a run of one win in six top-flight games.
The hosts competed well in their last game at Liverpool until falling behind to a Raheem Sterling strike, and since then all the talk around Upton Park has been about Diafra Sakho. They will be relieved to have got away with just a fine, but here they will be looking for the striker to again prove his worth.
Manager Sam Allardyce has got a lengthy injury list to contend with, but he is also aware that his side has much more strength in depth than it did last season, and they will still prove more than a match for the Red Devils. Should they triumph, the gap between the two sides would stand at just four points.
It was a much more comfortable assignment against Cambridge United in the replay than it was in the original FA Cup fourth round fixture for Man Utd, and Louis van Gaal has set his sights on winning that competition, but he is still very much in a battle to hold on to a top four place.
Robin van Persie has had his critics this season for a lack of goals, but he showed that he is still a top-quality striker with a fine performance in the last Premier League outing against Leicester City. This should be a lot trickier, but the pace of Angel Di Maria could be the difference.
West Ham will be without central defensive duo James Collins and Winston Reid, while Andy Carroll is unlikely to be risked due to an ankle problem.
The away side have Ashley Young back available after injury, but are still without midfielder Michael Carrick.
