Noble was impressive in last week's win over Sunderland.
Zola told whufc.com: "Mark Noble obviously came on and gave us a lot of energy and enthusiasm and those things, right now, are priceless. So I'm very pleased that he's back on form and I think he's getting better and better.
"It's important [that the other players step up]. Scott is a very talented and important player for us, but we have to remember that, last year, we played without Scott for a long time and got good results. We have to be a team. We know that if everybody works hard as a team then, even if we are missing one important player, we can get a good result."
