After grinding out four points from a possible six to stop a run of six defeats confidence within the squad is high as the Hammers prepare to visit a stumbling Liverpool side.
Talking to Sky Sports News, Zola said, “I always believe and I still believe that we're going to stay up. It's not going to be easy.
"We need to keep fighting because this has been a season where results have been strange.
"You'd like to win all the games 3-0 and when it doesn't happen you sometimes don't like it.
"I know they are trying very hard all the time and that is all that I'm asking for."
