What's wrong with West Ham? How are a team that finished seventh in the league last season now one point above the relegation zone?
Slaven Bilic's men have made a miserable start to life in their new London Stadium home after 112 years at Upton Park.
Is the relocation behind West Ham's troubles? What are the Hammers doing differently this season? We take a look at the stats…
West Ham have only scored 15 league goals this season while they have conceded 29.
Andy Carroll has missed much of the season after being injured during a Europa League tie against Astra Giurgiu on August 18. He returned as a sub against Arsenal on Saturday and scored within 10 minutes.
Carroll and Dimitri Payet were West Ham's top scorers last term with nine each, but the latter has also appeared largely absent this term - and not through injury.
Despite a spectacular solo goal against Middlesbrough in October, talisman Payet has struggled to find last season's form - taking nearly half as many shots on target per game on average.
In addition, Mark Noble has also created fewer chances, taken fewer shots and has not scored or assisted one goal this season.
Striker Diafra Sakho has also missed the majority of this season with back and hamstring injuries, while Simone Zaza has failed to fire since his arrival on loan from Juventus.
However, Michail Antonio has bucked the team's under-performing trend and netted six goals, all headers, and earned an England call-up during Sam Allardyce's brief spell at the helm.
West Ham's approach play and work ethic doesn't appear to have changed drastically since their move to the London Stadium.
Across the pitch, their number of tackles, duels won, aerials won, passes, crosses, dribbles, average possession and distance covered are all almost identical to last season.
The Hammers have missed left-back Aaron Cresswell, who has only managed five league starts this season between knee and groin injuries, and a one-match suspension.
Last season, West Ham conceded 14 goals from errors, surpassed only by Aston Villa (15). This time round, the London club have also shipped a league-high six goals from errors.
Four of West Ham's six errors leading to goals have occurred at the London Stadium. But despite that, the Hammers have actually picked up more points at home than away.
However, as the chart below shows, their home results are still well off last season's form at Upton Park.
So, West Ham need Carroll to stay fit, Payet to start trying his luck at goal, and address defensive errors if they are to rekindle the form that saw them narrowly miss out on Champions League football last season.
