West Ham owners David Gold and David Sullivan have promised they are doing "everything they can to fix the situation" following the club's nightmare start to the season.
The Hammers finished seventh in the Premier League last season during Slaven Bilic's first campaign in charge, qualifying for Europe in the process.
But West Ham's move to the former Olympic Stadium has brought trouble on and off the pitch, crashing out of Europe to Romanian minnows Astra Giurgiu while five defeats in six games have left them in the bottom three of the Premier League.
"There is no question that this has not been the start to the season that we were looking for but rest assured we are doing everything we can to fix the situation," joint-chairmen Gold and Sullivan said in a statement on the official club website.
