Following their 1- 1 draw at Upton Park Tony Pulis said he felt his team should have finished the first half with more goals.
He said: "The worst thing that happened to us was half-time.
"We watched West Ham defensively and noticed one or two things we thought we could exploit. We’ve practised it about five times over the last few days.
"We can’t turn those draws into wins. If we had got the second goal it would’ve taken the pressure off the lads."
