Sam Allardyce
West Ham boss Sam Allardyce believes that his team can spring a surprise against Chelsea on Saturday night - by taking a leaf out of Newcastle United's book and the draw at West Brom.
Over recent times, the Blues have suffered some unbelievable defeats and also drew games they ought to win.
And Sam, who believes his team can learn from Chelsea's defeat at Newcastle, aims at discovering where the weakness lies and taking advantage of it.
"Newcastle frustrated Chelsea and started the process of winning that game by keeping a clean sheet and scoring a free-kick then sucked them in and hit them on the break for the second," Allardyce said.
"With that result for Chelsea, there's a chance to see where their weaknesses lie. But anything less than top form for all of our players would make life difficult for us. We will have to produce the end product because chance creation will be harder."
However, West Ham have only scored twice in their last four games; and Allardyce charges his front-men to convert created chances.
"In terms of our goals, it's not that we're not creating chances but we're not converting them. Our chance conversion is among the worst and that has to improve," he added.
"To take the pressure off us all we need results. We haven't achieved that so far, and we need to turn the performances into results.
"We played against Spurs and scored three goals, we could have scored more goals against a lot of teams.
"In the striker area, we are not delivering goals in the game. We have outplayed a lot of teams since we have played without a striker. The tactical side of it has worked, but we haven't taken our chances."
West Ham will face Chelsea in the Premier League this weekend.
