West Ham United boss Sam Allardyce has revealed that he is concerned about his side's current lack of form.
The Hammers have won just one game in their last nine outings going into the game against Swansea City this Saturday.
Allardyce has admitted to being "very concerned", but insisted that his side are not the only team going through a poor run.
"We are very concerned at this moment in time," said the 58-year-old. "We have only taken five points out of our last eight games and we know that is not good enough.
"But you can have these spells, it is not unique to us. Fulham won [against West Ham on Wednesday] and it was only their third win in 16 matches and Norwich have been the same.
"Lots of clubs like us have had this spell at this moment in time where we have gone a considerable amount of time without the number of wins we wanted."
West Ham are currently seven points above the relegation zone in 13th place.
