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.

"The facts are there for everyone to see. We know we are letting in too many goals and not scoring enough, but be assured we will sort the problems out.

"We will turn our season around."

West Ham's move to the renamed London Stadium has also encountered problems off the pitch.

The lack of atmosphere has been criticised with the stands so far away from the playing surface, while Hammers' fans fought among themselves during the 4-2 home defeat to Watford on September 10.

Gold and Sullivan said: "We stated last week that we would be putting measures in place to make the London Stadium experience something everyone can be proud of and we would like to thank all our supporters for their support in this regard.

"Supporters can rest assured that we will not be slowing our efforts despite the match against Southampton being completely trouble-free, and we will not stop working until everyone feels they have a stadium to be proud of - on and off the pitch."
