I thought we played very well,” Zola told the official site.
“I told the players that what I saw in the first half and some parts of the second half was, between our box and their box, the best I have seen West Ham play.
“There were some quite good movements so I was pleased. We just need to improve a little bit and maybe take chances to shoot more. Sometimes it is so easy for us to get into those positions that we think it is easy to get the ball into the goal.
“I think we should be more clinical but that is something we will improve.”
