West Ham captain Declan Rice says his side are "underachieving as a group", but that any pressure on manager David Moyes after Saturday's home defeat by Leicester is "nonsense".
The Hammers have suffered nine defeats this season, with four of those coming at the London Stadium - having lost five home games in the whole of last season.
Rice said it is "probably the best West Ham side we've had in years", but added: "If you look at the quality of players we have at the moment, we are underachieving as a group."
The players were booed at the full-time whistle after the 2-0 defeat by Leicester, with many supporters leaving the ground after Harvey Barnes doubled the Foxes' lead following James Maddison's opener.
