West Ham had matched their top-four opponents for most of the game but were undone after a James Milner cross-shot was deflected over Rob Green by Lucas Neil's leg with only 20 minutes remaining.
Zola told the official site, "It is hard to describe for me. We had so many chances. We were playing against the team that is fourth in the table and we are just one point from relegation but you didn't see that on the pitch … the team is performing well and creating chances, doing everything well but coming away with no points."
"It makes me so upset like you can't even imagine. I'm upset, I'm frustrated for my players because they deserve much better than this and the crowd deserve much better than this. It is impossible that it will carry on like this that's all I can say about this."
"What can I do? I don't just give up, I need to be strong about this and this is what I told my players. We have to start making our own luck. If a team plays like this there is no way it can be like this forever and that's what I can say. I am very sorry for them, they deserve better than this."
