Zaha was again outstanding for their 0-0 draw with Manchester City.
Hodgson said: "I mean really he just puts on excellent performance after another in for the team.
"The big question for me, I suppose, with an element of scepticism which always creeps in when you've been in football a long time is how long can he keep this going?
"Keep giving performances like that, week-after-week, with very little break in between, it amazes me.
"For me, and for Palace fans and for the club, I can only hope he can keep it going."
