West Ham's 3-2 defeat to Leeds came after a run of six matches in 22 days, due to the rearranged fixture with Norwich City being squeezed in between the FA Cup and Premier League clashes with Marcelo Bielsa's team.
Hammers manager David Moyes was unhappy with the scheduling and did not see why his team should play in midweek when Leeds were afforded a week's break between games, despite playing two fewer league matches than his side.
West Ham twice fought back to level things up at the London Stadium but were undone for a third time by Jack Harrison in the 60th minute and despite a glorious Jarrod Bowen chance late on, the Hammers were unable to find a third equaliser and lost their first match in five.
