Sam Allardyce expects an improvement from his Hammers players after a fifth consecutive Premier League game without a win against Hull City on Saturday.
The inability to take chances has left West Ham struggling desperately to find a match winning formula since their opening day win over Cardiff City.
And Allardyce wants his players to start converting their chances as soon as possible, starting with the trip to London rivals Tottenham Hotspur on Sunday.
He told whufc.com: “For whatever reason at the minute they’re not going in the back of the net and that’s cost us.
“We played well [against Hull] but we didn’t finish properly.They’re the ones you’ve got to pinch when you don’t deserve it. More important is winning when you do play well and we certainly didn’t deserve to lose on Saturday.
“We’ve got to take it on the chin and now try and get some points against Tottenham and Manchester City.”
And Allardyce has put recent form down to a problem with injuries, including the telling absence of club-record signing Andy Carroll.
“You’ve got to try and ride your way through while Andy’s injured,” Allardyce continued.
“Teams suffer when your best players aren’t available and what you can’t have is your best players not available for long periods of time.
“In our case you end up where we are now towards the bottom of the league, which is not where we should be on our performances and our chances away from home.”
