West Ham boss Sam Allardyce has told critical Hammers' fans that they are "talking b****cks".
Allardyce dubbed the fans, who were vocal about their loss of confidence in the team after the Hammers lost 4-2 loss to Reading, "deluded".
The West Ham squad are fighting for promotion and look set to compete in the playoffs.
"Negativity around here has been very much in the forefront recently, which has been strange for me because we have lost one in 12," Allardyce told the Daily Star.
"You get opinions about our results like, 'James Tomkins shouldn't be playing in midfield because he is a centre-half.' You get that b****cks that goes round.
"What happens is I look at the performance of every player and say to everyone who says that: 'You're talking b****cks.'"
He added: "[Tomkins] played in that holding role for three games with 10 men - that is how short memories people have. That is how much b****cks is talked about in football.
"I don't listen to that drivel because what bothers me is that James Tomkins plays well."
West Ham vice-chairman Karren Brady has backed Allardyce to remain as West Ham boss even if the club do not get promoted to the Premier League.
She told BBC Radio 5 Live: "Yes, he will still be in charge next season - definitely.
"David Sullivan [chairman] wanted Sam - they have a very good relationship.
"Obviously the Reading defeat was difficult for everybody. We were hoping to win but we certainly haven't given up the prospect of automatic promotion or promotion, if we have to, through the play-offs."
"The minority of fans who boo are more than entitled to their opinion as paying customers but at the same time, so is Allardyce."
"We've had a few seasons where we've watched terrible football and this season we've been full of resilience and resolve. Apart from the Reading defeat, we're still on target for a promotion spot."
