With all respect to West Ham, historically speaking, this isn't a difficult fixture for United. Winning at home to the Londoners has been all but a 'given' over the years, and the facts back that statement up - the Red Devils have taken 20 wins from 23 Hammers visits to Old Trafford since 1986, a run that has taken in six wins in a row and five consecutive clean sheets against the visitors. Sam Allardyce's side have won just twice in 17 Premier League trips to play United and haven't emerged victorious since 2007, when they picked up a 1-0 win. What's more, the Hammers are currently one point and a place above the relegation zone and are struggling for their very survival this season. With fixtures running thick and fast, it is games such as these that United really ought to be winning.
